James, Just in case you haven't watched it, TJ tapes all his classes. If you go down to machine maintenance, it might help. I usually try to attend them online because of the Q&A at the end of the class, but I think I skipped this one because it was on full size machines and we just have Desktops. I always learn stuff from TJ's classes. Sorry if you've already watched it.http://www.shopbottools.com/mSupport/tutorials.htm
