Coal ! the stuff I'm holding out on , is the ballance of Linear motor force / to wieght of peen / to compression spring arangement and rebound obsobtion.....that's the reason I started with the 165#er apreciate the input keep it comming

Yeah, me too, I've been reading about the new fords and motor unveiled today. Talk to you tomorrow.

Smiths!!!! ????.....I say again ,I have never used any power-hammer ....the big boys @ Ladish have a counterblow hammer .....two like hammers aimed to colide on the work-peice.....no anvil ..........I beleive the main focus in making this was to lessen the concusion On the surrounding city of Cudahy Wi. (not sure)

but it also has the advantage of providing symetric deformation on the workpeice....

If a hand-held Dagger blank for instance was drawn out with this counterblow approach
you would get the added advantage as well .....uniform shaping , and less pounding of the earth in your niehborhood ..........the L.I.H. lends itself to this method ....but possitioning the blank would be a learning curve at best I fear .........Thoughts ?????????

Thanks Phil........

P.S.the oposed set of rams could be horizontal I spose .......conventionally vertical ????

OPPS !! forgot to put up the appropriate avitar .....

[coalsmoke]

I'd keep it a conventional vertical configuration. Its easire to use tooling when you can rest it on the piece, and, I think most peope would just shy away from learning something different. There's always another mousetrap out there, whether or not it be better is what most Smiths want to know. Now, at least for me, if it ends up in a configuration I have never seen first hand, let alone used, I might be prone to just shy away from it and move on to the next hammer, like the Iron Kiss Hammer. It doesn't matter how good a hammer is, if you can't get people to try it or warm up to the idea, you won't be able to sell it. This all ties back to the fact that a lot of us are pretty set in our ways.

Any of these what you're talking about?

I fondly remember helping an old smith in Thailand in the late 70's. That man could forge machetes like no one else. He had just a clay forge on the ground and used charcoal. His anvil was a sledgehammer head embedded in a 20 foot log of some very hard wood. He had one or two hammers, that was all. He could make knife after knife and every one looked exactly like the other, though the size varied by the amount of metal he started with.

The air was supplied by two hollowed-out logs having wooden pistons that were pumped by hand. The seals were chicken feathers stuck on with tar. I got to pump air for him...lots when forging, easy does it when heating for the tempering process. He was pretty particular, but I got the rythm down. If you even pumped hard for a half a stroke after he'd removed the blade from the fire, he'd get annoyed. Waste of charcoal, not to mention distracting. The guy was probably pushing 70, but he was tough. I still have 3 knives he made for me. At the time, I think they sold for about $2 or so. He would refurb one for about 75 cents.

I recently imported a bunch of these, though they are not nearly of the same quality. But they are hand-forged spring steel, and they do the job.

Oops, double post somehow.

HELLO TO ALL,
i am a member of BAM. BLACKSMITHS ASSOC. OF MISSOURI.
to forge weld, the metal has to be almost fluid, and then you sprinkle
borax onto it, and pound it together. i always used a coal forge,
but now have a gas forge. much cleaner, and faster, and of course,
more expensive to operate.

Vicegrip,

I think anything to far from the the basic little giant style will seem odd and the interest will not be there. You can make something really creative and if you got a well known knkifemaker or blacksmith to back it, it might get attention but odd, is odd and most people just keep on moving.

boiling this down to a L.M. or L.I.M. powered hammer....L.M.>to Hyrolic-cyinder>Hydrolic-Hose>to Slave-hydolic-cylinder> to nitrogen-spring,so-as to soften or harden the impact ....and provide a signal-source for reversing the ram...and a soft & hard limmit switch for top of ram stroke....> also the second Hydrolic hose two complete the circuit.....

on a C-frame constructed of heavy-wall tubing.....with desired anvil arangenent in the base
and sortof a landing gear with 70s chrome slots ....so as to lower the hammer to the ground at Hammer-INs and RonDavouoxessss and the like .....tounge welded from 5/8" rebar tapered bridgework up to the hitch.....NO CUP HOLDERS

HotFoot You out there ??? can you work-up a conceptual pic of a strapping but somehow slightly grizzeled smith

Fastinating stuff, I had read that a Samuri Sword was 10,000 thin sheets of steel folded
and hammer forged untill it was the finest Sword anywhere .

[Bob Warner]

Brasco,

That is not quite correct. Samuri swords were made of wootz. Wootz, is a steel that has bands or sheets of micro carbides within a tempered martensite or pearlite matrix. It is a mixture of wrought iron and charcoal with glass. The carbides in the metal showed as a pattern on the steel and became known as damascus. All createdby the method of making the steel.

As for layers you talked about. It is easier for the knife or sword maker of modern day to recreate the look of woots by layering different steels and forge welding them together and then manipulating them into a pattern. It is very rare to see layer counts upwards of 400 because at that count the layers would be so thin you would get carbon migration and the steel would basically no longer be layers but instead one new steel created by virtually mixing the steel together into one new steel.

I have smithed for quite some time and loved forge welding. The biggest job I ever done was some chain and rings for a civil war reinactor. 50 feet of forge welded chain and 28 rings and holders plus many misc. pieces. I use "smithy" coal it is actually just low sulfur low trace coal that I actually can purchase just an hour away from my home. Currently I am unable to do any of this work due to a motor cycle accident myself, life has been on hold for the last 4 months...

Now if I could get as good with my stick welder as I am with my forge and anvil I would be a happy boy... at least I could get something accomplished...

[Bob Warner]

IronRoseFarms,

I hope your injuries are not as bad as mine. I am at 11 months now and still trying to heal. It takes time, it sucks and it hurts. I am still in pain with every step. I found out that I am allergic to Morphine after getting several injections of increasing amounts to try to stop the pain.

It can cost you a lot. Mine cost me (so far) a year of my life, my ability to get around, my job and my insurance. I have not had income for 11 months. Since mine was a hit and run, I had nobody to go after for anything so I am just stuck paying the "beyond resonable and customery" charges by the hospital and doctors. I did not go to the last four months of doctor visits because I could not spend the $1350 per month for COBRA insurance. When I walk into a job interview, you can see them loose interest because of the limp and it becomes the topic of the interview. Then, no call back.

Also, since people in big cities "don't want to get involved" they do not stop to help or to be witnesses. I had no witnesses but had 13 calls to 911. Since there were no witnesses, my insurance refused to pay with uninsured motorists because I could not prove I got hit and MAYBE I just fell off all by myself.

This stuff can really alter the course of your life. I hope you turn out better than I have with my wreck.

Best of luck,

Bob
