I'm in the process of setting up and adjusting an ancient (1940 vintage) 12 X 36 Clausing lathe. One problem I have with toolpost stability is the lack of adjustment in the retaining bar that holds the far side of the saddle down.
The saddle runs on a V on the near side and a flat on the far side, while the tailstock does the opposite. The retaining piece that holds the far side of the saddle down is a simple bar retained by two bolts. There doesn't seem to be any adjustment.
Making even moderate interrupted cuts I can feel the far side of the saddle lifting about 10 thou or so. I'm thinking of machining a quarter of an inch off this bar and fitting a gib with three adjusting screws and locknuts, but I'm wondering how this system worked properly in the first place. Is this just decades of wear requiring compensation?
