I had been flame hardening silversmith stamps for years and years, staring into the fire to judge the color, and all of a sudden I was night blind REALLY bad. I'm sure it did not happen overnight but I just noticed it overnight.....Joe

it's all in the heat-treat!
We're finally dryin' out here in w Pa. Even have blue sky out there this morning!
Headed off to the shop to make tomahawks. Billets been settin' there since January. Hope I remember how......:-)

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.
Even at my age, one sometimes forgets that the final answers come from the workbench, NOT the cad drawing......Joe

Loren T., that is not new info. My PSA numbers had been erratic since my early 50's. It shot up and red flagged my cancer. It would have been undetected without the PSA and subsequent biopsy. As it was it was caught early and I was able to be treated with radiation and without surgery or chemo. YMMV
Loren T - Tue 20 Mar 2018 09:48:50 #0
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. I used to think A1c was the third revision of the first model of a new product. And PSA was Pacific Southwest Airlines.

On the days when I am feeling great, the power hammer design flowers and grows and expands, and when I am not feeling so good the thing turns more basic and simple and "just get it done" style.

We gave been barn cleaning and working on a splitter/press affair.
It has not rained in 180 days.
Dry is fashionable these days but not very becoming.
Trying to figure out how to rain dance in a birthday suit that is wrinkled pretty bad from all the dry weather.
The splitter/press is ready for wheels and a slide on the table of it.
No better than I weld it takes some grinding to straighten up the bed for the slide.
JOE hope you are faring well this days. Some days I am on slot some days I am not on slot. The sad part is--No body but Helen and I seem to give damn. Grin Been that way for years.
Nah, not really two Nietos have been helping(doing)with the barn clean-up.

Ramblings from Southern Utah
We had an extremely mild and dry winter, and now here it is spring. Friends in western Colorado say the same thing. Cow camp cabins in the high country that are normally snowed completely over have only a foot of snow.
We are planting some cold weather plant seeds in the garden and have pepper plant seeds in peat pots inside.
Baby chicks came last Friday and are doing well.
I'm going to fire up the forge one of these days. A friend wants some branding irons to wood burn a sign for his driveway.
Take care my friends!

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.
Good luck to all

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.
Jeff Reinhardt - Sun 22 Apr 2018 07:05:18 #0
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.
Joe Rollings - Tue 24 Apr 2018 10:28:36 #0
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

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
Loren T - Fri 27 Apr 2018 08:09:40 #0
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.
Joe Rollings - Fri 27 Apr 2018 11:05:25 #0
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
Jeff Reinhardt - Sun 29 Apr 2018 06:52:44 #0
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.
Joe Rollings - Wed 02 May 2018 22:58:27 #0
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.

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.

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!!
