Belts... and why nobody changes them. :/

Second, and more insidious, is that the bearing farthest away from the tailstock is a light press fit. It takes force on the jam nut to press the bearing in. Not tons, but in the order of perhaps a hundred pounds. So a bearing pusher has to be made that presses the spindle out, and holds against the nearest wall of the headstock. don't transmit the force all the way through the spindle as the pressure on the casting may crack the very thin headstock casting.

When I went through my Jet, I made a lap to take the left end of the spindle down to a sliding fit for the bearing . It was so tight, it was difficult to adjust end play.
