I’m designing up my ROR obs for my dob and plan to start building in the next couple of months. I’m sure I’ll have a few more questions. But for now, I’m thinking about the track system the roof rolls on.

I’ve seen a lot of designs with a concave type wheel running on a v-angle. My question with that, is how do you keep the roof attached so it doesn’t blow away?

I’m thinking about using a system where the wheel runs inside a C-channel. That way the wheel will be locked inside the channel, and secures the roof to the structure. Anyone use that or have links to information?

Do you lock the roof in position once it’s closed with tie down bolts or similiar?

Do you accept that the obs isn’t totally sealed as a gap remains between the roof and walls? I guess the gap could be as little as a few millimeters. I thought by sheeting down below the gap that will provide a certain amount of protection from the outside.

Finally, where do you guys get your wheels and tracks from?

Lots of questions there, so thanks for helping.
