[TheForge] 15Ton Press

ed,

glad you got to see the video. he makes quick work of that bowl doesn't he? also he uses no ram guides but stresses that the cylinder rod be large enough to take the side load. i think keiths rod is 4" dia. if i ever get around to building a press it will be just like keith johnsons. i think he used batsons book for basic info but not build plans.

btw i got batsons H frame plans and could not imagine forging upside down. this dog is too old to learn that trick. low center of gravity? isn't everything. what's the point?
