The quill lock on my Grizzly 1007 no longer holds the quill from moving when using fly cutter. I have removed the two aluminum wedges that hold the quill and cleaned them. Even using a plastic hammer on the handle won’t hold it. Even if I hold the hand wheel the quill will move a few thousandths over six inches of table travel. This wasn’t a problem when the mill was new. Something has worn, but I can’t find what.
