I got a great deal on a 10' Prodome that was well used and also unused for the past few years. When buying it the dome rotated OK manually, none of the motors were connected so could not try them. Now that I have it set up and used it for over a year manually I have determined that 30% of the wheels do not actually touch the dome ring. I suspect that the original owner miss-drilled some of the wheel mounting holes, a 32nd of an inch will cause no contact with the wheel. I believe this may be contributing to problems using the drive motors to rotate the dome (it binds at certain locations). My question is has anyone ever tried modifying a Prodome to attach the wheels to the dome itself which would ensure contact? I understand the ramifications relative to also modifying the base ring (or building a new one from some other material) and requiring some form of alternative capture system to ensure the dome does not blow away. Anyone with any experience with this or a mechanical or structural engineer interested in a small side project?
