[TheForge] press design

[Chuck Robinson]

Hey Mark,
Enerpac presses are used for cold work.
If your working 2000 F stock  a 10k press is overkill.
At the slow stroke rate you have, your stock would be a bitch to work
My 40 ton  7" bore press moves  hot  5" round stock at 2.5K  PSI.
I would be very reluctant to work within 2 feet of a 10K press. A 
hydraulic leak could be pretty serious.
James is right, sell the stuff and buy a 6" bore cylinder and a 3K PSI 
pump. Get Batson's Hydraulic Primer Manual
