OK, I have a question for anyone who has replaced a belt. I have an older Shopsmith Belt sander and tried to replace the belt for the first time. I released the tension as instructed and installed the new belt. When I turned the belt tensioner knob clockwise to lock things in place - things seemed OK, but when I tested the belt, the cam lock on the tensioner know always springs open and the belt comes lose. Anyone have any ideas as to why? I'm a bit befuddled by this.
More to my problem, I notice that when I turn the belt the tensioner knob will turn counter clockwise and that is what is releasing the catch cog and releasing the belt. Does this many any sense to anyone? Do I have a worn cog or what ever???
I have had experiences where I have had to adjust for a slightly longer belt. If this is the case, you can reposition the idler drum (top drum). The manual addresses how to do this when talking about different belt lengths. You also might want to re-tension the idler drum. This is also addressed in the manual.

OK I found out that I didn't have the idler drum properly tensioned - that must have been part of the problem - I also adjusted the tracking which helped alot too. I think I'm ok now.
