Once it is square I can then reverse the rotator without disturbing the fitting to the OTA. I imagine this would be much more accurate than pointing a laser at a center spot. Do you imagine this as a reasonable procedure?

Peter, if I'm understanding you correctly, I dont think this will work since the point where the dial indicator needle is, will or should be at the same height. In other words, tilt in the adapter has just added a constant offset. If you could put the dial indicator on one side then the other and noting the difference, it would work... but you'd have to move the dial indicator the exact same amount each time.
Another alternative is to mount the dial indicator on the cross slidd of a lathe, then put your adapter and rotator if you like, in the chuck. Now you can move the dial indicator around with the cross slide, knowing exactly how much you are moving it by looking at the measurements on the cross slide wheels. I did this with my previous focuser.
