So this is something that was an issue from just after I got the mount about a year ago. Everything seemed fine the first few nights out, but then the DEC mechanics seemed to be rubbing. After talking with Mr Losmandy on the phone, and after tinkering I thought that I had it solved. It seems to be back again. Let me see if I can explain it. When I loosen the clutch on the DEC, and turn it, there is a rub. this is happening between the graded ring and the worm assembly. If I remove the graded ring altogether, it seems to be fine with no rubbing.?
In the past I thought that I had fixed it by following instructions and re-adjusting the worm block to center it better, and I didn't feel any rubbing, but now I've noticed it again, and I can't seem to adjust it out. I'm left with just removing the graded ring to stop the rubbing. This is OK, but it opens the axis to more dust. I'm not sure what to do. Do I need a new graded ring? I don't see any way to adjust it so that it does not rub.
