72 and sunny???? we are not to see 20F for at least a week...... -1F this morning. At least I haven't seen a skeeter in a month or so.......hahaha

It was 9 degrees this morning which is pretty cold in Richmond VA.
In other news, I put the body back on the chassis of my '57 Chevy resto-mod project. However, the engine sits a little too far back, so I'm redoing the motor mounts for the 3rd time which means pulling the engine out again.
Friday, my friends from CVBG Bruce & John & I are going to the Eastern Shore of Maryland to the annual Gichner's Memorial Hammer In at Dave Hutchinson's farm. It's always a good meet & helps kick off the year's events.
Tom C - Thu 11 Jan 2018 09:32:25 #0
Gichner's was a good meet. About 100 folks braved the frigid snowy winds to attend. Dave Hammer was there to demonstrate his tiny "Cricket" power hammers. Judy Berger & Blue Moon Press had lots of metalworking books to peruse. Kirk Sullens was the featured demonstrator & forged an octopus, Russian rose & a frog. He did a good job.
Next is the annual Boone's Pasture Party at the end of February in Louisa County, VA.

I'm the only one who's posted in the last 2 weeks. Is it time to say "So long, it's been good to know ya?"
I have repaired the motor mount mistake I made & have proceeded to adjusting the body & fastening the steering column. Next is spot painting the door openings & their circumferences in prep to mount them.

Tom I have wondered the same thing myself. I hate to see this group disband
as I have enjoyed it over the years.
Hopefully more will begin posting. I see several are active on Facebook.

I too would hate to see this page close.....
Seems like the numbers keep dwindling.
Is anyone trying to work in this weather? I'm sure glad I roughed out 2 or 3 dozen blades before the deepfreeze hit! Every 5 or 6 days we get a brief respite and I go out and heat treat a few blades in the gas forge. Gonna break again this weekend!!

DAERRELL-- I have really enjoyed your administering this forum.
I appreciate the effort.
I have been having eye problems, makes it hard to hunt and peck.
I do check here the first thing when I turn on the 'puter.
Buck, Bruce, Tom C, Loren, Joe, Alex, Plain Ole Bill---having an old mans moment with name calling, and a few more that check this board regularly would really miss it if goes by the way side.
I don't know how many of the old "Junkyard" bunch are still around. We like to have "Prolapsed" when Neil quit.--
I think Ellen must have passed. I have not been able to rouse her for a while.
I for one, would hate to lose your support.
Blessings from the panhandle of TX.
Beautiful day today.

I have a business card with her phone #. I've been hesitant to call it but maybe I will to see what's happened.
I have an inkling she's passed because she hasn't replied to our queries.
Re; this forum: I started with Keenjunk in '96 a couple of days after we got our first computer & I found Neil's site. I have made a lot of friends, learned a lot about blacksmithing (& other stuff) from that site, then Sparky's & now Darrell's. I participate in other forums, but keep coming back here because it's simple, stream of conscious format resembles a bunch of guys standing around a pickup bed, shooting the breeze. It's something that, had you told me in my younger years that I'd be able to talk to people all over the US & the world, much less share photos with, I'd have said "You're crazy!" It's what's good about the 'net.
Chuck - Thu 18 Jan 2018 22:08:46 #0
We have been on a lot of years. Can't remember just what year we started with The Junkyard. Lots of great guys/gals. Some fantastic blacksmithing---art has been produced through the years.
I think I built my farrier forge in the 2001 or early 2002. I went to Joe Cordova's hammer-in in 2003, I think.
Met a lot of well known folks in the knife world.
Perry, Okla. Purcel, Ok
Bill, Dianne Davis, Glenn Franklin, Nathan Robertson would like to hear from them some more. Steve Parker, Thomas Power Jerry Duran lots of folks to remember.
Everytime I think of Papa Wilson I have a sag in my rhythm. All my kids and grand-kids know to stay a-way from galvanize.
Waugh was always admired.
God has been good to all of us, even the ones that rubbed dogs bellies instead of bending a knee.

Thanks for the support
I really like this site and the people that post on it.
I'm guilty as most of you about just reading and not posting.
I have learned much from you guys and am still trying to put that knowledge to use.
I know I ruffled a few feathers when I first started. At that time I was simply trying
to clean up the spam.
At this time I am almost full-time in my shop with several projects in process.
The current priority is rebuilding an old BOSS 10. Once I get that done,
I will be using it to make some parts to get my air hammer running.
The BOSS 10 will start out as a three axis CNC mill. I also have a 12 x 36 Enco Lathe. Eventually I will convert it to CNC also.
With the knife grinder I built, and the propane tank forge I plan to try knife making.
Chuck, I understand about problems typing, I am a very poor at two finger typing.
That is why I bought a program called Dragon speak. It types as fast as I can talk.

Gotta Add My $.02
worth about Thanking Darrell and missing this site too if it were to close. How else would I know there will be a machine shop in Ocean View, HI? You worried about incoming NK missiles down there, or was that just Honolulu? Don't recall ever seeing one of those reader boards on the Big Island.
Been busy w/ a new lean-2 project myself (pics posted). Need to move a 'bunch-o-crap' out of my shop and separate the wood and metal BEFORE I set a pile of sawdust afire with a hot spark and park the newer truck outta the weather... Seems at 70, doing it myself, in the winter (Western OR style... not REAL Winter like a lot of you have) everything just takes Forever.... Had to make my own brackets to attach the joists to the pallet rack rails too, good thing I had my shop and tools.
Anyway, I'm pretty much just a 'lurker' by nature but take great comfort in knowing that when I do have a question or something to share about blacksmithing, or most anything to do w/ metal, I will get a straight forward answer here and maybe some pictures of how to do it.
Speaking of pictures, I find the gallery a great resource too, losing that would be a big disappointment.
And I Really Enjoy Chuck's 'life stories'.
Thnx again Darrell and Everybody....

I echo many of the feelings expressed here concerning this forum. I think the numbers of contributors dwindles for many reasons. We're all getting older. I'm 72, soon to be 73. We've reached the stage in life where our friends and acquaintances are going away, leaving us with memories, good and bad. Our physical abilities are more strained, most often supported by a plethora of pills. Life has changed drastically from the days of Keen junk.Computer generations are not 20 years like humans, but shorter and shorter. Just think of all the new stuff that has cropped up,(and died),over the last couple years. My son, who is 42, hasn't gone on his computer for a couple of years. Everything is done on his i-phone.
2 1/2 years ago I moved to Sun City, Arizona. I promptly joined the metalworking club. After 40 years of welding, fabrication, and smithing I was eager to help impart my knowledge to anyone wanting it. What I discovered was a political quagmire run by a bunch of oldtimers who jealously guarded their domain, NONE of whom had ever worked a day in the metal trades. If someone wanted to know how to do something, I was invisible. 90% of the clubs activities centered around a plasma-cam. I left them and moved on. Now in Oklahoma, I have the use of my son's 40 x 50 shop and have a dozen projects in progress.
I too feel that Ellen may have passed, or is no longer able to respond. I visited her several years ago in Mesa where she lived and had a very nice shop. I enjoy reading other peoples entries and would be sorry to see it go away. Many thanks Darrell for your efforts. (Please excuse the rambling tone of this entry)

Been scrounging around the shop and finding all sorts of stuff ive been accumulating, For starters I found the mat'ls to make a 9-10" long ribbon burner - even a 50lb bag of unused castable refractory - bought some crayons today and will start the process of making a ribbon burner this weekend between other work scheduled already. Hope everyone is going into this year healthy and happy. - Jeremy K

Tanner went with me. t o eye-ball some log splitters.
I intend to build a splitter while thinking of using it as a press when the wood detail is done.
I know the difficulties. but will plan before hand on how to move the floor up( drilling two holes in a re-enforced shelf to hold the bottom flatter with added dies).( will leave the splitting wedge below} I have some grand-sons that will help me figure it out. They will probably do the actual building.
The gallery is cherished.
ALEX and all that post pictures are much appreciated.
JOHN ODUM has been quiet. Hope all is well with him and MURTLE.
I am still conservative but think others should have their own ideas.
Love this bench, pick-up, hammer-in---How ever it feels to everybody.

I haven't visited too often in the past year and half and it's even longer since I posted. Didn't even get to any blacksmith meeting/events last year. I had to re-invent myself for work, and became an independent contractor for a group that issues quality certifications to lab's testing aerospace materials. Last year kept me really busy going world wide for audits. This year the start is the same, but looks as though it will slow a bit after the first quarter and I might be able to actually doe some smithing, (if I can remember how to swing a hammer). I've also had a few health issues - atrial fibrillation (under control with meds) and I need to plan on a knee replacement this year. I've been putting that off for too long.
It's always good to be able to come back to this site and see/hear what people have been up to - as Jeff said, I'll try to mend my ways.
brucegodlesky - Sat 20 Jan 2018 08:03:54 #0
Golly , look at everyone comin' outta the woodwork (BOG) Good to see!!
Gavainh, you still in Latrobe?
Startin' to red out the part of the shop where I haven't been for awhile. Lost some W2 and feel it may be hiding in the wood collection......
Mixed feelings about FB. Incredible outreach for small bidness but I get increasingly weary of all the whiners........

I'm still in western PA - my wife and I have homes in both Ligonier Township and in Jackson Township near Cranberry. I'm mostly basing out of the Jackson Twp location, as I'm doing a lot of travel by plane - it's a lot easier to get to the Pittsburgh airport from Jackson Twp than from Ligonier. I'm currently in France for a week and a half of work - naturally the really neat nearby castle is closed for January. Going to try to get to the "black" cathedral in Clermont-Ferrand tommorow - construction started in the 1300's and it's called black because it was built from local black lava rocks "Notre-Dame-de-l'Assomption Cathedral" I did find out that France has a chain of Irish shops "Le Comptoir Irlandais" decent selection of Irish, Scottish, and Breton single malts.
Going to try to get to the PAABA meeting to be held at John Groll's shop in February - for a change, I'm not running off for an audit somewhere. If my schedule doesn't change, I'll get to add Poland and the Czech Republic to the list of countries I've gone to for work.

I called Ellen's cell# & got a "this number not in service" recording. The landline for her business went to a fax noise. I'll keep investigating.
It's 60 degrees here & I have the shop door open to let in some heat.

WOW! What a pleasant surprise to hear from all of you this morning! I too check in every morning and have been saying I need to post.
Sure hope you can keep this site going, Darrell. We only have flip phones and donít text or do any social media. Iíll be 74 in April and just donít really care to learn how to do all that. Also, I sure can relate to the not being able to do what I used to be able to do. We had a feed store in Colorado for awhile and I could carry 3 50# bags at once. Now just one is a challenge!
It has been terrible dry here. Our total preciptation for 2017 was 5.86 inches. Weíre doing a little better this year. Weíve had 0.41 inches this month.
I too have been busy cleaning and organizing the shop. A neighbor knows I do blacksmithing and has two nephews that are interested. They are going to be here in a couple weeks and I was asked to do a demo for them. Isnít it amazing how knowing company is coming will motivate you to clean?
Thanks so much for your efforts keeping this site up Darrell. I started way back when Neil was doing it. Be a shame for it to go away.
Tom C...thanks for checking on Helen for us.
Jeff Reinhardt - Sat 20 Jan 2018 19:04:16 #0
Got the hot water heater in and heating by about 1:30 this afternoon. Youngest just reported that she has hot water, and no visible leaks.
My good friend Butch Sparks came by to help with the heater on his way home from a half day's work, then we moved to my shop and made messalunas. In a short afternoon we made 8. starting to stock up for this coming season. Also made a new design for me a rocking pizza cutter. It is forged, needs grinding and heat treat.
The snow is melting and 48F outside felt like a heat wave.
Jeff Reinhardt - Sat 20 Jan 2018 19:51:57 #0
Forgot to mention that as I was closing the gate valve to isolate the hot water tank, the valve bonnet came off in my hand, leaving me with a valve body but no bonnet-stem gate etc, and so full pressure cold water was spraying me and the hallway. Dropped to my good knee and swiped the ball valve to isolate the house and the spray stopped. Boy was that surprising. Never ever had a bonnet come off like that and let me tell you I have opened and closed many in all my years in old factories and old houses. Lost maybe a gallon but it sure flew around.
Chuck - Sat 20 Jan 2018 23:16:44 #0
Gonna tell little of what we did today.
During the Christmas family gathering. The nietos put up a 37 X 21 car port for Us.
The concrete guys had put in weld pads when they poured the slab back in 2003. I do not know what they anchored the pads with.
We had a 60 and up wind a couple of weeks ago. It made a little concrete dust spewed out around the weld pads, on three 4X4 thin wall rectangular pipes.
Another nieto and I decided to not wait on the other boys to come back. This grandson can't stick weld thin walled pipe. He drilled the holes in the concrete He did it all but the welding.
I have been virtually one eyed all my life. stigmatism in my left has made it a follower. I now have wet Macular Degeneration in the right(strong) eye. SO I have a black screen to see through on my good eye and no depth perception with my weak left eye. You would have laughed to watch a fellow --blind n one eye and can't see out of the other---weld the 3/16" angle iron to the thin walled pipe.
I got it done but it does look like a blind fellow did it by touch. The other boys will come by and clean up the welds for us.
Supposed to have high wind tomorrow--Maybe we got it hooked down some better.
We did bolt the angle to the concrete and weld the pads to it where we could. It should be alright. Grin
Damn I like this getting old. The cheeks of my butt are going to be sore tomorrow. Grin.
Good Night & God Bless

Welding thin wall pipe
My first job as a welder was working in an ornamental iron shop while going to college. I was brand new at it. I had a friend's father teach me how to strike an arc and run a bead one Sunday afternoon so I could apply for the job. All we had were Lincoln AC tombstone welders and 6011 1/8" rod which is high penetration. Our ornamental columns were made of 16ga. tubing and when welding them I learned to keep a rod with the flux removed to use as a filler when blowing a hole through the tubing. Essentially gas welding with an arc, rather than a torch. I got good enough at it that I started doing piece work and made very good money. My boss never had enough funds and many times he had to pay me over 2 paychecks.

Well after several months of waiting for parts to come in the mail the CNC mill actually ran yesterday.
Now comes the process of cleaning up the wiring and adding a couple of bells and whistles.
One thing is flood coolant, another is an encoder to read spindle speed.
Then begins programming with Fusion 360 to make parts.
First project will be to get my hammer running.
brucegodlesky - Tue 23 Jan 2018 15:34:12 #0
What kinda hammer Darrell?
My Fairbanks is generally out of commission this time of year. Too much frost heave. Have to rely on the hydraulic press or Armstrong powewr :-)
Keep tryin' to talk myself into a hammer rebuild and move the drive wheel to the rear so I can mount a motor on the back of the frame.
Weather has moderated so looks like some forge time before long. Saw a lil video MS Ray Kirk did on forging small intregal blades. Have to give it a try befor I forget how.....
Darrell - Tue 23 Jan 2018 23:18:25 #0
I have an air hammer that was a basic Kinyon style.
The shuttle valve O-rings kept going bad. That was a bit expensive counting the shipping.
I am replacing that valve with a hydraulic valve. Right now I am working on some
prototype linkage that I hope will be more like a Steam hammer.
Had the mill up and running today and made a couple of parts for the hammer.
Kind of slow going learning the new mill software and the CAD/CAM program.

Glad to hear your hammer project is coming along. The only time I was around a power hammer was at Robb Gunter's school. It was a Little Giant. Sid Suedmeier was there too. He had just purchased the Little Giant company.

Darrel - o-rings
Darrell - Do you have an inline oiler on your air hammer - I put a "T" in the piping and unplug the "T" and a few drops of oil and re-plug the "T" then hammer away. - no problems since.
Jeff Reinhardt - Wed 24 Jan 2018 16:09:59 #0
Darrell, most hydraulic valves are lapped spool design, IE they have a spool that is lapped into the bore. They depend on the viscosity of the oil to slow leakage across the lands of the spool to an acceptable level. I fear you will not be happy with the air leakage in this type valve. One of the items that is usually changed in a steam hammer that is being modified to air is to refit the valves with seals. As Jeremy notes oil is pretty essential to the seal life in pneumatic items. Also the RIGHT oil. Oils like Marvel Mystery Oil and others of the Patent Medicine type will often degrade seals faster then no oil. A really good choice for seal life is ATF. Works well and does not hurt seals. Is very stable in viscosity vs temp as well. The antiwear package in ATF works well in cylinders as well. In a previous century, while working at a major pneumatic valve and cylinder makers lab I got to test seals against various oils. Marvel Mystery oil would turn regular Nitrile seals to mush overnight. Several of the "airline oils" were little better. Hydraulic oil in low viscosity say 10 weight was quite good as was ATF.
Darrell - Wed 24 Jan 2018 21:04:23 #0
I have an in-line oiler that I am using 10 weight hydraulic oil.
The original shuttle valve spool lasted a long time, but the new thin ones hardly lasted a month.
I know the hydraulic valve that I'm using is new, but I am detecting no air leakage at this time.
At $70 plus and shipping and waiting for the shuttles it won't take long to pay for the hydraulic valve.
What would happen is if the hammer sat for a couple of days the shuttle would stick in place
and I would have to take the end off and tap the shuttle in both directions and free it up.
Two or three times of that and those thin seals that they used to replace O-rings were shot.
Jeff Reinhardt - Thu 25 Jan 2018 15:57:58 #0
Darrell, sounds like if the hydraulic valve does not work, you need to change brand/style of valve.If that occurs let me know, I can advise on some very bullet proof valves.

I inherited a bunch of stuff a couple of years ago, and have been slowly selling it off a bit at a time, and nobody stepped up for the old ditch witch trencher, so I had me a plan to remove the hydrostatic tranny and use it to build the ultimate finely controlled power hammer.
Just about the time I was getting ready to scrap it out, somebody called and wants to buy it, but them I figured out there is another of the trannys in an old wheel horse tractor I can use.
Seems like a perfect solution to me for absolute control. The one I built with a slipping belt was not controllable by me, at least.
Seems like I plan more than I build these days, but I'm not much for chilly weather, even chilly weather that would make you guys from cold country put on your swim trunks and go sun bathing......Joe
Jeff Reinhardt - Thu 01 Feb 2018 16:28:59 #0
Joe Rollings, a friend of mine built a guided helve with a hydro tranny and it was not good. the tranny was loud and the hammer did not perform well. When he saw my hammer with a tire clutch he rebuilt his and is much happier with the hammer now.
I used the rear hub bearing assembly from a 1990 Gran Caravan, with the spare tire from same. For the pivot I used the center from a wheel off the same. That way I could weld the pivot and not have to touch the compact spare wheel with any welding. Just bolted the center on over top the spare using the lug nuts. Been running that for years.

I wish I had seen RAY CLONTZ's "Piddler" hammer before I built mine.
Ray is damn near a genius developing tools and jigs. He is great place to get advice.
I have my "50" running on flat dies and my home built is running for on fullering dies.
I am now about through the figuring stage of building a 37 ton splitter/press. Got all the steel, 17 HP vertical motor, tank and axle.--need cylinder, control, hydraulic motor. Some pretty weather. Grin

Catching up on my reading, did notice Toms post couple of weeks back about the silence, thanks Tom as it did wake everybody up. I'm usually silent just mostly a reader, not checking the post often as there's been a lot on our plate here to occupy our time, wife diagnosed with uterine cancer back in early November, had operation Nov. 30, going through chemo now and radiation later, stage was 1B so that was good news. She's a tough girl, is taking it well and with all the prayers we're getting I'm sure all will turn out ok. Someone else may have mentioned it but I thank you all for posting as I enjoy reading (Tom C, Bruce, Chuck, Bert, Loren, Jeff. Joe, Gavainh, Buck, Jeremy and anyone I left out)and special thanks to you Darrell for hosting.
Our NM Artist Blacksmiths Assoc. meeting will be at Ward Brenigar's shop in Santa Fe tomorrow Feb 3 and anyone is invited to attend as guest are always welcomed. Directions can be found on NMABA's website, if interested just look it up on the ABANA site under affilites. Ward will be doing a demo for us, his last since he is retiring and will be selling most of his shop equipment that will be identified at the meeting. I posted a photo of a letter opener with slant ladder pattern mokume scales I made for iron in the hat, pattern not aged enough yet to see in the photo. LXIV,

Prayers up for your wife, Alex, and
very cool letter opener. Any hints on the Mokume making? Do they need to be fluxed?

Joe Rollings - Fri 02 Feb 2018 20:48:32 #0
and while I am rambling.....
Has anybody ever built a power hammer with an air pressure based spring? You gotta understand that these days when I start building a machine it is rarely because I really honestly need it, but because I really want to build it. Lucked out and got to build a big bandsaw for a client a few months ago, but I'm getting the fever again and no client handy, so I may have to build something and either use it, sell it, or make it part of the estate sale, which will give my executor another reason to tear his hair out.... :)
Anyhow, I am getting ready to scrap out the front and rear axle assemblys from an old dump truck for the springs and such (leaf springs look like about 4"x 1/2") and I keep looking at those old air brake pots. You can get the new pancakes for them and using one for a spring in a mechanical hammer would allow one to adjust the spring pressure to find the sweet spot.
On second thought, not enough stroke. Must be good for something, though. Looks like a 10" pot would develop around 7500 pounds of push. Maybe an air operated vise.....Joe

lotsa interesting stuff here lately.
Me? I'm kinda hibernating....... That dang roadpig got everyone in a tizzy over 6 more weeks of this stuff. I saw him in the garden just before Thanksgiving and regret I didn't make him yote bait then........
This is good forging weather:-)May get bout soon and fire up. Have a run of hawks planned. That should keep me busy for a month or so.....The pattern welded billets are "seasoning" in the open air HA!
Jeff Reinhardt - Sat 03 Feb 2018 07:49:04 #0
air brake pots
Joe Rollings, air brake pots would make a great edge gluing table for wood. used in cabinet shops all the time. edge the wood, glue, lay in table, turn on the air to hold the wood edges together. They usually have a crank adjustable back stop for different width glue ups.
When I worked at VOGT we had about 70 or so air vises in 2 sizes. looked like a regular bench vise, but the back extended out for a diaphragm/spring set up similar to an air pot. the jaw screw threaded into the diaphragm center so the gross adjustments were made with the screw and the finally travel for production clamping was by applying air. they were set up to only travel maybe a 1/2", more for safety then anything. Still had a guy stumble and trip and stomp the treadle as he grabbed the vise jaw to stop from falling. Cost him most of his thumb and first finger. Of course a safety treadle with cover would have prevented that.
Mike B - Sun 04 Feb 2018 07:49:38 #0
Even if you had enough travel, air springs would not be efficient for a power hammer. When the air compresses, it heats up. Some of that heat goes into heating the body of the spring rather than in helping it extend again. Perhaps that would be manageable if there were other advantages, but it's an issue you don't have with mechanical springs.
This effect is actually a plus on vehicles -- which already have shock absorbers specifically designed to convert some of the motion into heat.
Joe Rollings - Sun 04 Feb 2018 20:29:51 #0
Only possible advantage I saw was the adjustability and ability to fine tune.
Compression only heats air because of locating more heat molecules in less space, aside from very small increase because of friction. Without constantly increasing pressure, heat should not build up after initial charge of compressed air is added, as I see it.....Joe

If you're using air as a spring, it heats up as it is compressed on each stroke. It the cools off again when the air expands. In itself this wouldn't be an issue. The air would heat as it was compressed, increasing the pressure and requiring the motor to work harder to compress the spring. But that extra pressure would help extend the spring again. The two strokes would be mirror images, and nothing would be lost.
However, some of heat is lost to the walls of the spring. If you compressed the spring in the morning, you'd have to fight against the increasing pressure as you compressed it. If you then let it expand in the evening, the air inside would have decreased to room temperature, and you'd get less push out of the spring than you put into it.
Obviously the air in the spring isn't going to cool to room temperature on each stroke of the hammer. But it will heat up on each stroke, and some of the heat will go to heating the walls of the spring and the air around it. That lost heat represents energy you put into the spring and won't get back out of it (except to help heat your shop).
The inefficiency isn't that big a deal in itself -- you can just throw a bigger motor on the hammer.
It's also possible the spring would overheat. I don't know how likely that is, but the hammer would exercise the spring more than a truck would (except maybe on the worst washboard road).
Also, the pressure in the spring would be lower when you first started the hammer, since the suck walls would be cold and therefore suck the most heat out of the air. As the walls heated up, the rate of heat loss would drop, and the air pressure would increase. Again, I don't know how significant this is. You might be able to manage it by bleeding a little air out of the spring as it heated up.
I hadn't thought about being able to fine tune the spring. That might make it all worthwhile. On the other hand the pressure increase as you ran the hammer might drive you nuts.
Hopefully someone will build one and tell us.

Joe, I'm not an expert on forging mokume, so far I've only used quarters and fifty pieces, have found that the newer quarters seem to weld up better than old ones. using a stack of 16 I flatten them by hitting with a treadle hammer to take some of raised defination out, clamp them evenly with a small "C" clamp style visegrip, wrap the stack with just enough tape to hold them in place then clamp them between 2 pieces of 3/16 x 2 inch flat mild steel bar. I'm using a 4 in. and a 5 in. long bar with holes drilled 3 in. apart for 1/4 in. bolts to secure the coins. Just make sure the bolts clear your flat dies when pressing them to weld. I'm using the press in the photo I posted a while back. I heat up the coins and clamp until the whole thing is all the same color as the interior of the forge taking care not to overheat which will melt the nickle, you will know when that happens and when I see little flicker on the coins I go to the press and press them down to about 1/2 the original thickness, pop them from the clamp and then they can now be heated to a red heat not quite as hot done to weld them and hammer forged to about any shape. No flux is needed and the tape will burn off no matter what kind is used, I use masking tape. The number of coins does not have to be 16, I've done 22, could be even less. I've also welded the billits pairs. I smooth the surfaces on the belt sander and welded up the pairs. You can keep stacking them to make a billit as big as you want. I use a 1 inch thick fire brick in the gas forge so if I do a melt down I don't have a mess on the forge floor. I did one that ended up with 64 quarters. Sorry about the long explanation but hope it is helpfull.
Joe, I still have a HP DOT cylinder for you. LXIV, .
Alex Ivey - Sat 10 Feb 2018 11:30:46 #0
Didn't mean to imply that I melted 64 quarters. The 64 quarter billit is not finished with pattern yet, will do later when I can get back in the shop. Had cataract removal surgery on both eyes Wed. and Thurs so have to take it easy with the eyes for a while.
Am registered for the Abana Conf. and hotel in Richmond so hope to see some from the forum, probably Tom C. for sure. LXIV,

ALEX-- I hope your wife is faring better. Pretty tough old coot to have both eyes worked over at the same time. Hope this is 100% successful.
While waiting for my eye to improve.--Wet Macular Degeneration.
I am looking for a good stout cylinder 4X24--or bigger, control valve. I am going to build a splitter. Later I will make some blocks and a slide for the cylinder end to convert it to a press.
Hoping to find a cylinder stout enough for a 30 ton press. A new cylinder this big is too expensive too play with on my ever reducing SS check.
I plan buy a 16 GPM pump.
I have a Muncie clutched pump, but to get the RPMs to get the GPMs is tooo much for my 17 horse B & S engine.
I have an old Dennison pump. It won't put of the GPM that I will need.
The neietos will get more use than I will, but would like to have a press to use for a while.
Hope everyone skips the flu.

I have been lucky and haven't needed it done, but my wife had both done about a week apart 6 or 7 years ago. She had a choice of lenses, basic for no extra charge, medium for $800 each, or super-duper computer type for $3-4000 each. Went with basic. Had worn glasses for her entire life. Now has 20-20. Needs to wear readers is all. Total time for surgery was about 2 hours from check in to check out. Actual surgery was 7 or 8 minutes.

Sorry 'bout that
Had trouble getting through the first time with the new computer. I want to encourage everybody contemplating eye surgery to get the best doc recommendation possible from somebody who knows what they are talking about. I didn't, and it was a big mistake.
New lens slipped (they said), legally blind in one eye for months, detached retina, repairs accomplished by better docs, but they could only do so much. Eye is now 20/50 and going downhill pretty fast. On top of that, she could not get it numbed, and I could feel every thing she did for over two hours BIG TIME. Even when she poured water in it it felt like battery acid.
Not trying to scare anybody out of doing it, just make sure your guy or gal is up to the job, because not all of them are.....Joe

Well, we finally are getting some wintry weather. Been real nice 'till lately. It's 14* here this morning and still very dry.
I had cataracts done a few months ago and sure am glad there were no problems.
I now have 20/20 in both eyes and just need 2x cheaters to read.
I have astigmatism in my right eye, so that took a special lens, unless I wanted to wear glasses full time. The insurance would only pay for a standard lens. They said the better lens was "cosmetic"! Anyway, $850.00 was well worth it to get 20/20 vision.
Sure hope everyone can dodge the flu. Linda and I have been lucky so far.

Splitter press build
We have been gathering parts and metal. All we like now is the cylinder. May do a separate guillotine build for the press. Scared of the long splitter cylinder.
I found and old cattle hydraulic chute. Every thing seems to work on it. Plenty of controls, pump, good hoses, reservoir, filer housing. Single phase 3HP 1750 RPM motor. It will bring enough to pay for the rest.
I am yet to know what the GPM is going to be on the 40 series pump with a 9.5 BS engine.
If it is as it appears to be a Cross 40 D 12 it will be just right. Can't tell for sure what the 12 means on the pump.
We have the metal will just have figure the gussets. The press has to be safe. Going to shield the clevis and rod part above the top die.
Got some coal from Aquilar, Colo. Propane is too high here. Just one supplier.
Skiff of snow today--about a half inch--dry snow.
Ready for spring planting of garden.
Eye is no better but I can tell which woman to take home from church(without feeling) Grin.

We've been watching the Olympics. Tonight, one of the speed skater's blades broke & he had to have it replaced. That got me to thinking that they must be some sort of alloy steel. Any idea what kind? Like a knife, you'd want it to hold an edge but not be too brittle. Maybe A2? D-2 would be too hard to sharpen I suppose.
I now have the doors on my '57 Chevy project. The front clip is next.

Joe, sorry to hear about your I guess you would say bad eye surgery. Had mine done at Pacific Cataract And Laser Institute in Albuq. by Dr Robert Ford who has done over 200,000 cataract surgery's. So far 2 weeks after the surgery both eyes are doing great. My regular eye Dr did the 1 week post op and says I will no longer need glasses, only readers. My drivers lic. had me requiring glasses to drive and that restriction will go away.
I read somewhere in the past about what is referred to as glass blowers cataract's caused by looking at the fire in gas forges and possibly the bright fire in a coal forge. The recomendation is to wear didymium safety glasses. Does anyone have any experience with them. LXIV,
Jeff Reinhardt - Fri 23 Feb 2018 17:58:14 #0
Alex Ivey the glass blower lens are the wrong filter for IR from steel. You need a plain green shade 3 or 4 or 5 for steel at forging temp. The make nice flip up shade 4's for safety glasses. For what its worth poly-carbonate lens as used in most safety glasses are a natural IR filter. Not sure right wavelength but the do filter even when clear.
Joe Rollings - Fri 23 Feb 2018 21:45:40 #0
My eye doc wrote me a scrip for a single permanently midrange tinted lens for my bad eye because when they screwed it up they also stopped the iris's ability to open and close.
People who made the glasses almost refused to make them that way, but it is a really big help to kill the glare in that eye. I have to have the same argument every time I go back for new lenses, but it is worth it....Joe

Dry weather--skate steel.
This ole country is drying out. they are calling for 5% to 12% humidity Tomrrow and Monday with a strong wind. Still have a lot of fodder for fires. I hope everyone is on the ball, watches what is happening around them.
There are ten or twelve places along the highway between here and Amarillo where they have caught road fires before they got out of hand. --About 90 miles. Blessings that they were caught before they really got to rolling.
TOM C. --I started to put up a guess--something between 1075 and 1095. These steels can be drawn back to a strong(not brittle) tough blade but still hold an edge.
Good friend of mine thinks his Macular Degeneration in both eyes was caused by quick darkening welding hoods. He was hard facing drill bits for a couple of years before it showed up. He was 64 when he first noticed it.
Forging steel could cause that. I have seen a couple of guys spot welding with a wire welder, no glasses or hood.
Mine was caused by sympathy pains for my wife. Grin

Skate blade steels
The company makes various blades with the 440 C being the expensive one & the 1085 for the budget minded. I thought it interesting that they used similar alloys to what bladesmiths use.
brucegodlesky - Mon 26 Feb 2018 18:21:44 #0
well, skates are a blade....:-)
420hc is a middle of the road carbon ss. IMO doesn't make much of a knife blade, a little bit better than kitchen cutlery steel. Does take a nice shine tho.hehehe
It goes without saying, the other 2 are old standbys in the knife bidness, easy to work and heat treat.
RWCase and Queen both use 420hc for their shiney knives. It's made right here in the Allegheny River valley by ATI.

I have a track loader that is a parts machine, and noticed a weight on the back of it that prob'ly weighs in at 1000 pounds. Has the Allis Chalmers insignia on it and has been welded onto 1" plate strips, I think with an arc welder. Stroked it a couple of times with a 12 pound doublejack and it dented nicely.
I would like to use it as an anvil for a power hammer, but have trouble believing that it is steel. Cast iron would be MUCH cheaper for weights.
The welds might be older than me, and none of them are cracked. Any wisdom out there?
I just bought a 10" I beam with a 5/8" web, 12 feet long, so I could fashion an anvil without the tractor weight if required, but if I can use it I want to.....Joe
Jeff Reinhardt - Sat 03 Mar 2018 07:16:39 #0
Joe, may be cast steel. easier to weld, and tougher, so may have been the choice in the allis foundrey as it would be less likely to break and crack in frame parts. try grinding, cast steel will throw the regular long stream of sparks and cast iron will be oranger and shorter and not branch as much.
Buck Brown - Sat 03 Mar 2018 11:06:56 #0
I agree with Jeff that it's probably cast steel Cast iron will arc weld with special rod, but it has a nasty habit of not staying welded. When the weld fails, it pulls a rut out of the cast iron. Peening the bead after welding helps
Joe Rollings - Sat 03 Mar 2018 22:21:10 #0
I was trying to figure how to get a grinder to it for a spark test, and then figured out I have an air grinder that will run off of the co2 tank I use for airing up tires, so tomorrow I will go spark test it.
Those old crawler tractors are from the 40's and 50's right after the war, so maybe lots of scrap steel around to cast. I know they threw enough of it away overseas.
I built one power hammer before, but was never very happy with it's control and sold it at a decent profit. This time I have the time and material to make a good one if I am smart enough.
I dunno if it has been done before or not, but I am going to build it with the crossed leaf spring linkage and a blue engine for power. Those blue engines have a remarkably good governor for speed control, and that way no electricity or compressed air will be required. I will construct a really effective muffler to make it comfortable to be around.
Will need to figure out how to match the hammer weight with the size of the leaf spring bundle, amongst other things.....Joe
Chuck - Sat 03 Mar 2018 23:25:38 #0
JOE- the more you can put under the hammer the better.
700 pounds and up would be where I would shoot on another hammer build.- 10 to 1 ratio.
Three or four leaf--plus 30", with a 60 pound total throw weight. This design kind of mimics a Little Giant.
4' X 4' packed caliche or concrete under it.
The Piddler--Ray Clontz has a good design on the spare tire hammer.
Got a good report on the Prostrate deal. PSA number was .47. Sounds good.

First time I read your previous post I missed the decimal point in your prostate number. Went back and looked again and was much relieved. Not the sort of things we were comparing with others in our youth, but times change, for sure.
Tomorrow I will go down and pull off the tractor weight and start sawing off the I beam sections to weld together for a base.
I am a bit paranoid about the spring for the DuPont linkage on the hammer. Seems like it should be sensitive to being either too strong or too weak. Anybody ever tried an adjustable air spring? I have plenty of leaf and coil spring sections so I will not voluntarily spend money if it is not needed, but it looks like it would be easy to make a mistake in that department.
So far I am calculating the anvil at 1000 pounds and the base at nearly 400 pounds. I can cut the hammer stock at any length up to 180 pounds.
NO limiting factors except, as usual, my own stupidity. Easier back when I could plead poverty as an excuse.... :) .......Joe
Joe Rollings - Sat 10 Mar 2018 21:36:58 #0
studied the problem a bit and I can see how to move the pivot points and change the levers around to alter the work load of the spring. Got a couple of rear coils out of an old Geo Metro today and will just have to work up all of the parts until they do the job properly.

Thanks for the info. I have spent the majority of my life without insurance, and with Medicare, I am learning a whole lot I never knew.
This comes with regular Dr. visits, and 21 pills a day. Oh, and a B-12 shot every month. I receive a report after a blood test, and I have signed less paperwork when taking out a mortgage than I have to read in test results. I now have a good Doctor who listens, lives where he works (a small rural community), and doesn't feel the necessity to order unnecessary tests. He reminds me of my Doctor when I grew up.

Power hammer is coming together, but I need some straight leaf springs and got no way to heat treat something that long, so I called the spring shop and asked them about dong it, because they do all kinds of stuff to springs.
Guy tells me he gets his 5160 already heat treated and arced and can alter the arc or flatten it or whatever in the press. Anybody care to take a guess if he is just getting it as rolled? If he is doing that, I can just buy 20 feet from admiral and cut it up like I want it and use it. Seems pretty hard when it comes in, so maybe it is used "normalized".
Jeff Reinhardt - Thu 19 Apr 2018 18:51:48 #0
leaf spring steel
I get what is called "Repair plates" and they are from Triangle spring co. Definitely already arched and heat treated. But the heat treat is not full hard. I can cut them with my cutoff bandsaw with a bimetal blade.My spring shop where I buy them will de-arch them for a little extra and that is what I use in my power hammer. He has a press and tooling made from the very large U bolts from truck axles. Pushes between the u bolt laid on its side between the legs and takes many many bites to easily level the spring to flat. The Triangle spring rep was there one day as I visited and he told me Triangle uses ONLY 5160 in the leaf springs.
Chuck - Fri 20 Apr 2018 23:19:35 #0
I have used 5160 in the 'done' stage to annealed.
5160 straight from the spring joints works for 'kindling splitters' but are to soft for dies in my 'Little Giant' fifty. I rose budded the face of the dies to a high(1400+) red, quenched in a warm Texaco quench, colored it back with a rose bud. It works pretty well.
JOE If your making a 'Helm' type just use it as is, while making the arch work for you. A couple of springs(used tandem)off a dodge one ton or even a 3/4 ton should work for a helm. It might be hard to figure the fulcrum.
I use 5160 drops from an Amarillo spring joint for knives. I anneal then re-harden and draw. I really like 5160.
BRUCE--I got suckered into going to Raton, NM for a G & K show. Neitos were gung-ho now they are dragging. I can't see well enough grind to a line or cut handle material to fit. Will just grind to fit. GRIN. Have blacksmithed enough stuff to fill a table, with some older knives.

Helve hammer spring
I use spraings tempered as bought in my helve hammer. Mine is a 70#.
Joe Rollings - Sat 21 Apr 2018 14:05:17 #0
Well, I took the advice and straightened the springs as instructed right down to pressing them between the legs of the U bolt, and it worked just dandy!
Turns out after much agonizing that the hammer will be 100 pounds, the anvil around 1300, the base plate is 3 four foot sections of 10" H beam welded together that should come to about another 600 pounds. Should be close to a 20/1 ratio, and I could have added more hammer but I dunno what I would do with more than 100 pounds of hammer. I can't pick up much more than 100 pound work piece any more, and even then I better be picking it up from a bench, not the floor.
Ready to address the pivot and guide, now. I was going to make the clutch a slipping flat belt, but I guess that tire clutch has such a good reputation that there is no need bucking success. I'm thinking I may use a stack of hard rubber wheels instead of a metal roller to rub against the tire, though. Might make the tires last longer and be cheaper than a big old slug of metal anyway.
Thank y'all for your help, and everybody be careful. We don't hold up like we used to....God bless.....Joe
Jeff Reinhardt - Sun 22 Apr 2018 07:01:18 #0
Joe my hammer has the tire clutch and it far out performs the slipping belt I had before. I used the rear bearing hub assembly off a 1990 Gran Voyager. It has a bolt flange, sealed taper roller bearings and has worked at 70# weight for years now. I mounted the lower pivot for the pitman that would have been welded to the compact spare to the cut out center of another wheel that fit that hub and then did not have to weld to the compact spare wheel. that took away the issues of welded to a wheel with the tire on it, I just used the same lug bolts that held the tire wheel on to hold the pivot wheel center on. I used a heavy turnbuckle from a building wind stay for the pitman and to give adjustment. Go as big here as you can as the threads take a beating load. My pivot for the helve is the rear cap off a hydraulic cylinder, with the mounting clevis to match. I used the original pin too. cross drilled every pivot for grease holes and added zerks for the grease. I use moly grease and have seen no pivot wear since 2002. I also uses rod end clevises and pins for the pittman end as well.I copied The Tire Hammer slide design and it works well.

Joe-Picking up from a bench
I can relate to that. I tell people that anything close to the ground is no longer my friend. I had a conversation with a guy in Washington State at a yard sale. He had a new metal building shop about 30 x 50. It was pretty much empty and I wondered what was going on. Seems he had it built for a retirement
project. He did transmission rebuilds and figured he would do some side work when he retired. What he didn't foresee was that he could get down, but not back up. AND he didn't have enough head room to put in a hoist.

Joe there are photos under my name in the gallery that show some of the details that may be helpful. I used a steel slug for the tire. It has the as turned finish on the rubbing surface. No observed wear since I installed it years ago. Some folks I know have used a Knurled surface and it makes the clutch too grabby and eats the tire. Have no fear of excess wear with a steel tire. Mine was made while I worked at the axle forge shop so it is a hunk of truck axle stock.

The forces in those machines are interesting. That spring provides a LOT of isolation for the parts holding and moving it. When I was running the one I built previously, it occurred to me that the linkages and pivot on the spring could be beaten to death in a couple of minutes under the hammer, but they run smooth and last long on the other end of the spring.
I also admired your trowels and other stuff. Would you care to share how much you sold those for? I am acquainted with a lot of mineral diggers. Again, thanks....Joe

trowels and stuff
Joe I sell the RR spike trowels currently for $50 each and I sell my Messaluna choppers for $45. The choppers and trowels are both on ETSY and the choppers are on Handmade at Amazon.The trowel sales peaks and ebbs, as does Mesalunas.
Joe Rollings - Thu 26 Apr 2018 20:43:25 #0
I won't get into your marketplace or even online. I just think the rockhounds and arrowhead diggers would "dig" them.
Got the toggle assembly ready to put together and starting on the offset pin for the crankshaft. I'll prob'ly not weld it to the wheel, but only because my eyes tell me I should not trust my welding amy more. Mig is broken down and the wheels I have a pretty thin material for stick.
I might just turn some really long lug nuts on the lathe, thread them, bolt a plate to the tops of them and put the pin in the plate.
Taking the project slow and enjoying it.......Joe

Joe, I am also questioning my welding. I haven't used a stick welder in years, and find out that old standby rod 7024 isn't stocked anymore, at least locally. I am replacing the tongue on a 25' trailer for a customer, and using a Miller Thunderbolt 225 AC I have had for 20 years. I forgot that the duty cycle is important, and when it just quit, I discovered I had melted the end off the transformer winding, which was aluminum. I have always wanted it to be a DC weld, and went to You Tube. For $25 I bought a bridge rectifier and rewired it. Now it is a DC and works great. I hooked up the High range, and just abandoned the low range. Now my welds are a lot better looking.

My problem is more in eyesight. I delivered a violent attack to a high lift jack handle with my head :) a long time ago that affected my right eye and it has had both good and lousy doctoring since then, some of which destroyed it's ability to react to light.
I simply cannot make out what is happening in the weld puddle like I used to. I guess I have some other rims like the one I will be using that I could practice on, but the idea of putting that kind of strain on the thin metal of the spare tire wheel has me picturing the whole plate coming off under load and giving me a thrashing.
I have gotten more cowardly in recent years, because at my age there is a decent chance that my heirs may be using or selling what I am building today....Joe

pivot mount on tire clutch
Joe Rollings, I would recommend using the lug nuts to hold another steel part against the clutch wheel as a geed alternative to welding to the actual wheel. That is what I did and it has worked well for many years. If you use the center of another wheel with the rim cut off, you may be able to use the existing lugs. if you use the rear hub bearing assembly as I did and then remove the backing plate and the brake drum it is pretty clean and the thickness of the brake drum is about the thickness of the second wheel center.

power hammer parts
I am working with the rear tire and wheel from a Geo Metro, which has 4 lug bolts. I took off the rear hubs which have the brake drums integral with the hubs and discovered that the splines on the lug bolts were a tad undersize to drill out for 1/2" uss threaded rod, so I drilled them, and tapped for 1/2" coarse thread, extended them a bit and will soon mount an old sprocket to the extended lugs with pipe spacers and weld a large nut to the sprocket to accept the crank pin.
Next chore is to either salvage the spindles from the Geo or turn fresh ones and weld them to a support block. Getting cranked as things come together.
Remaining major component is the guide for the hammer. Part of me wants to just go steel on steel and use a high quality grease, but another part wants to make brass gibs that are adjustable. 5/8" round brass is available for gibs and I have everything I need to make them, but doing it right is one thing and wasting time and material is another.
Any thoughts? And, by the way, thank you for your help. Nothing in this world is equal to a guy who has "been there and done that"....Again....thanks ...Joe

power hammer parts
Joe, I did a take on the tire hammer ram and guides. I used 1/4" wall 6" square tube with a 5" square tube for the ram. I used 1/4" UHMWPE for the bearing surfaces. Has worked well for 7 years and just now thinking about some new poly for the bearings. I used countersunk flat head screws through the tube wall to retain and that has worked well. The ram has a 3" or so think block welded inside the open end and was plug welded from the side. That is drilled and tapped for the dies. I filled the open remaining space with drops of 2.25" by .5" flat bar with lots of stick weld.I had two of those bars extended up above the tube to carry the rollers to ride above and below the spring. If I rebuild I will probably go to a rubber bushed link as there is a clatter as the rollers bounce back and forth against the spring.

DARRELL--- Which island do you live on? The Hawaii Island is catching it? Lava flow and quakes, bad mocus.
Not likely to let up anytime soon?
HOT and DRY here.
Planting garden--hope the heat does not turn up like it did last year.
We have had a steady high wind for weeks. Less than an inch of moisture in the last seven months. Fires keep cropping up around the panhandle.
I put a kiddy wading pool of water out(with a 2X4 in it)for the quail and pheasants, in case any wanted to nest around here.
We are closer each day to having a rain.
Darrell - Mon 07 May 2018 03:59:48 #0
We are about 80 miles from the lava outbreak. It is moving away from us and
the current outbreak is no danger to us. We did have a 6.9 earthquake a
couple of days ago. We were far enough away that it was simply a small shaking. It is quite a trial for the people that live in the subdivision
where the lava is surfacing. As of tonight, 30 homes have been destroyed.
The sulfur dioxide gas is quite heavy in the Leilani subdivision.
They let people in 2 selected areas to retrieve property when it is safe.

Power hammer stuff
To catch up anybody else who is building one, the easy way out for the drive wheel to rub the tire is an X series weld-on sprocket hub in the proper size bore for the motor shaft. The OD will be about 2 1/2" but one can bore and then turn on the lathe a 2" hole in a larger round bar and weld in the hub, if one has a metal lathe. That will get you an accurate hole for the motor shaft, a proper set screw and keyway to keep the hub on the shaft and running true.
Total price.....$12....well worth the money.....Joe
Jeff Reinhardt - Sun 20 May 2018 06:40:10 #0
Joe Rollings. The weld in hub is a good shortcut. My steel wheel to rub the tire is about 2 1/2" od so that would work as is on mine.

Hope everyone enjoys this special day coming up. It's not about the celebration , it's the sacrifice paid by many.
I always attend a small visitation by the local VFW to the "home" cematery where I was raised and a lot of family is buried. Lots of memories there......
Been attending since I was a kid.
Smithing content..... getting some cable billets cleaned up I started this week. Making a run of BBQ tools, flippers and squirrel forks. Labor intensive but fun stuff!!

Power hammer stuff
Power hammer is well along the road to completion, and have to come to a few decisions that would be a bit difficult to re-make after the fact.
Have a 7" mechanical stroke and guesstimate will have about 12" of combined total stroke. There is 16" of ram movement inside the guide, so I can do an additional 4" max of adjustment with the turnbuckle, and even more by adding and removing dies and anvil extensions.
The anvil top itself is about 10" deep, front to back and about 2 feet wide, side to side. It is an old tractor weight somewhere between 1000 and 1300 pounds, so the entire hammer may be near a ton, but it seems like I should put a smaller top on the anvil, like a 5 " round or square, up a few inches from the top of the weight, just because of the difficulty of finding a way to get tongs flat on the side of the hammering surface, if that makes sense. I have lots of material to choose from, including 3" square bar which I can double up on to make a 6" square, 3 inches high, or a 1" 16 X 16" plate I can cut any shape from.
I also have to choose what goes on the bottom of the ram. I have read endless discussions about dies V. bottom tools like spring fullers, etc. The ram is made from the 3" square bar, and it would be easy enough to put a 6" section of that crossways on the end of the ram and make a pins-in-holes arrangement to lock other 3" wide dies to that, but which might make it tougher to use bottom tooling.
So far, after I truly got started, things have gone really well, and I have made the guide with brass gibs inserted into milled slots and adjusting screws, got a removable plate system for the wheel and took far more time and care than I ever used to when building a machine, because at this age, my Grandson may wind up running it after I am gone, and it would suck for him to get hurt on my machine. Or anybody else, for that matter.
Of course, I realize most of the questions I have asked are up to the individual and have no 100% always-right answers, but anything along the lines of discussion about what causes the most frustration will help to make my choices. Once I have that guide mounted, it would be a major hassle to decide it needed to have a 6" block welded to or taken off of the anvil and the guide height changed.
I also wanted to add that if anybody has a surface they would like to add a hardy hole to, those same weld-on x series sprocket hubs come in square holes from about 3/4" to maybe 1 1/4", and one could drill a round hole topped with one of those and have a nice tight hardy hole.
Thanks in advance for any help......Joe

Stuff and hammer
ALEX Sorry to hear about the Missus. Hoped she was doing better. Blessings to y'all you are on our prayer list.
JOE you need room to change dies and work your metal and tongs--fullers. I like the room on my Giant '50'.
I would like to have at least 6" clearance including top and bottom, more if possible.
I work around my hammers to 180 or 200 degrees. Sometimes a helper is holding tongs or fullers from a 90 to me.
My dies are close to three inches wide and as much as six inches long.
Hope this might be something you were wanting to know.
Blessings to the folks on 'Big Island'.
Cimarron, NM folks got to go back home. Ute Park, NM still has 200 dwellings threatened.
Joe Rollings - Thu 07 Jun 2018 22:41:05 #0
Glad to hear
that ute park still HAS 200 buildings. News made it sound like they were all gone.
Good stuff about the hammers, Chuck.....Thanks......Joe

Anyone heard from Darrell?
We're in the high 90's here already. Need to make handles for 2 branding irons I made for a friend, so I better get it done soon.
Talked to a friend near Glenwood Springs, Colorado, my old home town. The Colorado River usually peaks after June 15th. It peaked the 1st of June this year at 50% of normal run off.

Finished re-building the Bridgeport and now I am converting the Enco lathe to CNC.
Made the timing pulleys for that on the Bridgeport.
Pulled the engine on my 98 Forester and fixed the oil leak and put it back.
Next project is to re-build my power hammer and see if I can get it to run the way it should.
Alex Ivey - Fri 15 Jun 2018 17:00:12 #0
Joe & Chuck
I thank you both for your prayers concerning my wife's cancer and treatments. She is done with chemo and radiation and things are looking better at this point but only time will tell if everything she went through works out for her. Her doctor that did the operation and guided her through the treatments is very optimistic that she will have a full recovery Thanks again guys. LXIV,
Chuck - Sun 17 Jun 2018 01:45:54 #0
ALEX glad to hear a positive prognosis.
The bad part of growing older is the gradual--sometimes drastic downward spiral of our health.
Looks like my eye deal is permanent, I will find something to occupy my time. Garden is off to a good start.
We got an inch and a quarter Friday, with another sixty seven hundreds this afternoon. This old country is going to be green once again.
The prospects for more rain this coming week seems good.
Tonight Derek, our fifth grandson brought a ten foot piece of two inch draw bar stock. I would guess this steel to be 40 series steel.
DARRELL good luck amigo, the volcano seems to want to turn its self wrong side out.
Keep the gas masks handy. Meter the Sulphur Dioxide(sp) bad stuff.

Big doings in the Old Dominion
Well it's less than a week to the start of the ABANA Conference here in Virginia. Our gild has lent a bunch of equipment to help out. I've lent a Vulcan anvil to the Learning tent. It looks like the weather will be cooperative with PM showers on Thursday only. I look forward to seeing my metal mangler buds here on my home turf. Besides the gallery at the conference, there are 2 shows of metalwork in the area. Gallery Flux in Ashland has a show of various smiths & CVBG has a little exhibition at Artworx in Richmond. I invite anyone to get in touch with me for shop visits or a trip to Dominion Salvage on Southside for interesting metal doodads.
