I am building a dome and mulling over the options for track and wheels. I want to drive it with automation eventually. It seems to me that grooved (V or U) wheels of some sort running on a track (perhaps rolled tube or a strip of 4mm steel or Al) will stabilise the dome laterally and have less rolling friction than castors on a timber ring. But is this extra structure (a track) really needed??



I would be very interested in any wisdom that those of you who have been down this track could impart.


Thanks
