[TheForge] Air Hammer

Tue Sep 30 19:40:00 2003

Yeah Ive got one too they are great, but it looks like from your picture the
cylinder has a huge rod which means the area under the piston is tiny which
means the 120 psi or so will only have 1 square inch or so to work against.
That means a slow upstroke. It sounds like you have run it though if you
know the bpm is 300, which is great by the way, Im lucky to get 250 out of
mine. So Im wondering if Im looking at the picture wrong, do you know what
size your cylinder is and what the area of the piston is on the upstroke
side? Its great BTW having the forge real close, I dragged mine over the
other day and was doing a heap of tapers, I was sitting down and didnt have
to move apart from swivel to get the next bar...
