Finished this 15ish ton press based on Jim Batson's great book.  The goal was to be able to punch a hole in a hammer billet then be able to drive a drift in and forge the blow out from the punching on both sides in one heat. I wanted speed instead of tonnage for less heat input in the punch tip for less galling and damage to it.  I accomplished that goal but currently do it two separately to take my time getting the eye right and not have to worry about doing the rest.  The motor is a 10hp 3600rpm baldor motor, the pump is a 22 low pressure by 7 high pressure and the tank is about 35 gallons.

The PSI does not have as much to do with it as cylinder bore size. Mine is 4" bore.
