[TheForge] 15Ton Press

[Ed Fasula]

Hi Chuck & Ralph,

I'm really interested in your ideas about using rollers.  I'm designing my 
press and I'd like to keep this future design in mind.  I haven't bought a 
pump yet - the compensated piston pump sounds interesting - do you 
basically set it at a given pressure?  Is it just one speed then?  I was 
planning on a Northern Hydraulics 2 speed gear pump, which wouldn't stop at 
a pressure but my piston has a valve to lock it until forced to move - it's 
off a construction fork lift.  So I could set it to a stock thickness.  Any 
idea on the power required to drive the roller?

Chuck, I'm really interested in seeing the structure for a 70 ton 
press!  How wide is your span?  The book has a 10" opening.  I'd like to go 
at least 12".  Have you ever wished to have it wider?  What is your die 
setup that you can change in 15 seconds?  I was thinking of using 3x3 
vertical bar and then plasma cutting blanks that I'd press around the 3x3 
bar (into a female die), that would form a box with one open end, then have 
a hitch pin with a ball retainer to run horizontally through the 3x3 bar.

Have you guys ever thought about making a hot shear with the press?

Can you pass along some pictures?  Please use edf@hutchtel.net
