Matt Marti Posted September 2, 2018 Share Posted September 2, 2018 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. press video.mp4.crdownload Quote Link to comment Share on other sites More sharing options...
