[TheForge] Power Hammer Foundation

[David E. Smucker]

A heavy wood pad / foundation as Bob suggests will work well.  In my old 
shop I had a 50 air hammer that I had set on a 1 inch horse stall rubber pad 
over a 4 inch garage floor.  I never had any problems with damage.  (In my 
current shop I have a 135 pound Tom Clark hammer but it is on an 8 inch 
reinforced concrete floor.)

If you can find an old addition of Machinery Handbook it will show some 
ideas on wood foundations for power hammers.  Since most 25 pound hammers 
are so low to the floor anyway a 6 or 8 inch hardwood foundation should 
protect the floor and get the die height up to a reasonable level for most 
folks.  (The 25 pounder had low die height because they were made for 
sharpening plow blades.)
