June 25, 200916 yr Hi, I would like to know if the # of the flypress is the capacities in tons. I'm looking for a 8 tons flypress. Does it mean #8? and is it okay for forging hot mild steel? John_zXz
June 25, 200916 yr What manufacturer? I do not believe that the different manufacturers used the same system; my #2 hopkins (??) is a Large H frame screwpress that was pretty much over the load limit for my small pickup.
June 25, 200916 yr Don't think the number mean much of anything except to the manufacturer. Certainly not tonnage, in my experience.
June 25, 200916 yr That Charles-Wayman press looks like a coining press, its screwthread looks too fine for a flypress.
June 25, 200916 yr You can't always compare sizes and numbers on all makes and modes of presses, especially on the older models. The #'s and weights on the new imported models could be considered a baseline because lots of people have them and the capacities are listed in lots of places, but all bets are off on the antique models just because there were so many more manufacturers, and they tended to number their presses any way they felt like. Probably the best way to compare is to measure screw diameter, fly weight and fly diameter and check against the charts of the new models. For example, my old Perkins #4E has the same screw as a modern #6, but a bigger and slightly heavier fly weight. And the frame alone weighs 1600#, not counting the factory made base.
