After many hours of careful measurement, I have my walls to within 1/2 inch of true round. However, I am still having two issues:
1/ The dome rotation motor is on a very flimsy bracket. It tends to twist and buckle as it rotates the dome. I have the three screw mounting and also have the extension bolt attached and tight to the wheel at the top of the pillar. It still twists all over the place.
2/ The wheels are constantly jumping the track (coming out of the shallow groove in which they are supposed to track- it is not only shallow, but the sides are not limits to the travel of the wheels, only a suggestion.
Obviously I will check the round again, but has anyone used external bracing to make the walls more rigid against the wheels to stop them from flexing and allowing the wheels to come out of track? Do others have this issue?
Until the problem of tracking is fixed, I can't use the dome remotely, which is the entire purpose of the dome.
