VERY impressive, based on what you've show i could probably build one myself. the inside of the ram? what is it threaded to? and what diameters did you bore it out to?? sim assuming since there is a "step" inside somewhere that it is wider at the top and the goes down to 7/8ths or 3/4's of an inch after a certain length? could you provide some details about that part of the machining? thats about the only thing that im unsure about with this press.
