the depth knob because I told you the round aluminum piece behind
it will not move,unless I an doing something wrong.Guy's I really
appreciate all the help.don't give up on me! Thank's
1) If it is a Mark V from 1980 it should also say shopsmith, Inc. with the serial #.
2) Then it be a cast
aluminum headstock.
3) The 'depth knob'(lets refer to it as the 'dial') should rotate between and stop at "0" and "4+".
4) The aluminum part behind the dial should NOT move.
5) The quill shaft should rotate with the 'aluminum part behind the dial' acting as bushing, and the headstock on the other end doing the same. There is a steel sleeve on the quill lock side(headstock bushing).
6) With the quill stop wingnut removed, there should be a keyed washer on the outside of the dial and one on the inside face. Both washers and the dial should pull straight off the quill shaft.
7) On the other end(quill lock) there should be a curved spring washer between the wingnut and the 'sleeve'.
8) With all these parts 'removed', there is only something inside that could be restricting quill extension.
9) If a visual check of the quill rack and pinion and quill bore does not reveal 'the cause', then removal of the quill shaft be next.
Nuf for now! Come back with what you observed.
P.S. If you cannot rotate the dial, then it is possible the keyed washer(s) is(are) jammed on the keyed shaft. If so 'they gotta come off!!!'
