I had an issue come up twice over the weekend, so I thought I would mention it here and see if anyone else has run into the problem and maybe keep others from going there.
Two separate customers at the American Association of Woodturners Symposium asked about tracking issues following adjusting the sanding frame angle.
After a bit of questioning, it occurred to me what was going on. If you're a little over-zealous in loosening the machine screws that secure the sanding frame to the motor, the frame can pop out of alignment when you adjust it...then when you tighten it up, the sanding frame will be angled relative to the motor and bottom pulley.
Make sure the frame is fully seated as you tighten the bolts back up. There are three surfaces, and all should be parallel and flush. If they are, you won't have any problems with tracking when you tighten the frame back up.

If you keep the back machine screw snug and only loosen the front one that is avoided is it not? I took your advice on that when adjusting the arm and it works a treat. Not least of which is that you only need loosen one machine screw and not 2. Or am I barking up the wrong tree with this?

Nope...it's the right tree...but...
You are right that you can leave the back screw just snug enough to provide some friction, and then just use the front one to lock the machine. However, periodically check the back screw. It can work itself looser, and then you've got the problem described above with misalignment. I've had this happen...granted it was on my demo machine that has more miles riding in my trunk (boot) than a season full of NASCAR races.
