[TheForge] Making power hammers

[Larry and Pat Brown]

It's a good place to put the mass. Also I think its more than just falling 
weight; as its the lift, the force of turning around the momentum, the 
pushing (throwing) the head back down  and the force of the head 
hitting  and rebounding into the lift phase. I would consider the only 
place that gets more stress is the anvil section. I have used uhmw plastic 
on the guides for my treadle hammer with no problems and I designed it so I 
could power it (which I still have to). I used angle iron to form a V guide 
arrangement with the plastic as a liner.
I have been thinking of this as an up coming project for myself, I would 
appreciate it if you keep me informed on how its going on or off list
