Are the quill bearings oil bath and is the pump mechanical or electric? I think Martin changed their lube system from the T21 to the T23. Joe or Darcy will know. The real beauty of those old shapers are inside the cabinet. The system to lubricate, the precision large bearings, and the large frame motor and guts to support all of it are impressive. Unlike new shapers, Martin hung the internals off a heavy base rather than relying on the cast iron top. New machines cheat on the base and save money by using the top as an anchor. Then they get a dip in the middle. Dave
