Bridgeport spindle problem | Model Engineer

5/12/2014· Try tightening the nose cap. If you move the quill down a little, there is a locking screw at the back, about 1/2" up from the nose cap, it should not be very tight as it''s easy to distort the quill, makes the last 1/2" of up travel very tight. Sometimes it''s not tight enough and allows the spindle nose cap to turn slightly.
