Yesterday the spindle on my Clausing 100 Mk. II Dual decided to stop turning. The motor turns, and so does the countershaft. As near as I can tell without dismantling anything, either the clutch/brake lever mechanism on the countershaft is in a state of constant slippage, or the vee belt from the spindle to the countershaft is worn excessively. It seems like the clutch/brake does work to take the headstock spindle "out of gear," but there's not enough friction somewhere between the countershaft and the headstock spindle to turn the spindle regardless of the position of the clutch/brake lever. (I've always avoided using the clutch/brake lever for fear of having it give up the ghost at some point, and I doubt whether the vee belt has ever been changed.) Part of the enjoyment of having an old tool like this one is that it be able to function as originally designed, so if the problem is the clutch mechanism I'd prefer to fix it instead of modifying the countershaft to make the clutch feature non-functional, but what ARE the choices of fixing versus modifying the clutch/brake? I think the Clausing part number for the vee belt is DL-258, long since unavailable from Clausing -- can anyone recommend a source for that?
Thanks in advance for any information/advice.
