Ram weight is about 80#, the anvil is a bit over 300#, and the base is 
another 300#.  I haven't timed the BPM, but rough guesstimate is around 
180 BPM.  Air cylinder is 3 1/2" diameter with a 12" stroke, though I've 
got a 2" buffer on each end at the moment, so it has about 8" functional 
stroke.  I've got a die spring on top of the ram to help avoid bottoming 
out on the upstroke.  Power is from a Quincy model 390 compressor.  It is 
a 20HP head being run by a 15HP motor.  With the rated motor it should be 
able to deliver 67CFM @ 175PSI.  So I'm probably getting 50+ CFM at the 
125 PSI I'm running it at.  The unloaders kick off about ever other run, 
so I don't think I'll be having any problems keeping up with the hammer.
