I ran into some problems attaching the main frame to the press base. Sometime during the 25 years the press was disassembled either the frame got bent or the guides on the press base did. Either way the frame was 3mm too small to fit the base.
With some bar clamps a crowbar and many attempts, I managed to finesse the parts together.
All the other bolts to fasten the bed guides and motor are missing, so off to the hardware store.
