Hey Gareth, heres a few pics of the recent PH build. I did away with the old school square dovetail dies and all that nasty shimming. It uses pinned round dies. This one runs on a DC motor, all future builds I will most likely use a VFD.
The entire machine is 3/8" plate with 1/2" reinforcement where the arms bolt to. There are no cast parts except for the motor pulley
These pics might give some of you guys out there some ideas on your own build.
