treadle hammer

[Mike Craddock]

does anyone have information on building a treadle hammer?
thanks

Bob Warner has plans you can buy at http://www.warnerknives.com/Training.html

I built my own from scratch, i'll have some pictures up later.

Ok here we go, a couple shots from the build day and the finished machine. 2 inch square 4 inch long dies are too big, go with 1 inch wide 2 inch tall 4 inch wide combo set and it will work MUCH better. I have a drawing set with 1 1/4 round that works great, the smaller the radius the more force is focused into a smaller area moving more metal.

base plate 3/4 thick plate

Full scale drawing, which REALLY helped a ton to get the rough measurements

Bolt on die setup

All the seperate dies plates and the lower anvil plate as well as ram die mounting plate

Side veiw BEFORE modifications to upper actuator location(see next photo)

Actuator relocation, this made the hammer hit literally twice as hard

reinforcement to lower treadle swingarm

stop spring to keep the ram from slamming into the front guard everytime the ram came up

SLIM LITTLE LADY AIN'T SHE?

If you have any questions shoot, I built it myself just by looking at pictures of others online, then did some personal modifications they did not have. it won't beat out a 25 pound LG but it sure saves your arm some work, and works AMAZING for tooling, I do all my chisel work for dog and dragon heads on this tool and having both hands free to hold the peice and tooling and hit hit hit hit hit hit as fast or slow light or hard as you like is very nice and comfortable.

Improvements, a solid anvil, a solid ram or a ram filled with lead/sand/concrete, and to have it bolted to the floor to make it completely sturdy(it's sturdy enogh to bang away as hard as you want). I'll have this beast with me this year at Ashokan if anyone is wanting a closer look.

I am interested in the hammer. Email me with your location and price. leggettc@emailaccount.com

 

[Keith_H]

these are interesting, how hard do they hit?

 

[Mike Craddock]

Thanks for the pictures Sam....
I think now I know almost what I need to do.

No prob Mike, I built mine using all standard size steel stock trying to make it as easy to buld as possible.

The force a treadle hammer hits with relative to your stomp is dependent upon the lever point (as sam found out based on his pictures)

For example, my treadle hammer does not have a very 'massive' head, but it hits quite hard because where the lever point -> pivot point is, it moves the mass it does have very fast for a lot of momentum.

The kinetic energy "stored" in a moving object is equal to 0.5*m*v^2. So double the mass, double the energy, double the speed, quadruple the energy....
