I'd thought about that - maybe cutting 3 1/2 sides, leaving lots of margin for error for the conduit. A couple of things I'm wondering:
1. How likely is this to really fix the problem, do you think? (Obviously if need be I can sacrifice the conduit.)
2. How messy is this going to be? I'm assuming I'd want to remove all of the equipment, electronics for the dome, motors for the dome before cutting because of the dust. But there are rollers and other components that aren't so easy to remove. Would that be necessary, do you think?
