I inherited a Delta 18x36 drum sander 31-250 from my father in-law, during the move an unfortunate accident caused the sander to be dropped on its side knocking the feed table off of it. Reviewing the original paperwork that came with the sander really doesn’t show me how the feed table was mounted. From the parts list I believe there where cap screws the thread into the end of the elevating screw, if this is so mine are sheared off. I believe that the elevating screws are a discontinued item, would anyone know where you can get these.
