[TheForge] Air Hammer Anvil ?

[Peter Fels And Phoebe Palmer]

Hello Madmike;
The rubber mat will help with the high frequency vibrations, but 
the low frequency ones that damage buildings will pass right 
through it.
I'm facing a similar problem, living on a very steep chunk of clay.
If your falling weight is 135#, then you will want a considerable 
mass under it as a first measure. I hope it was a very large 
forklift. More mass under the anvil=less transmitted vibration.
I am planning to build a foundation that suspends the inertial 
mass on springs with the hammer bolted on top. It will take a lot 
of reinforced cement.
I'd also suggest that the joint between the cast iron weight and 
the tool steel anvil be as well fitted as possible and have a 
large surface area.
You might consider mounting the tool steel plate up on edge. That 
would make more effective use of the mass and give better 
clearance for forging irregular shapes.....pete f
