Here is my idea for my 10" Newt.
It has Parallax rings already which are solid aluminium. I add another ring, ATM naturally, made up of 6mm aluminium with ply inbetween for depth and add wheels that are meant for sliding mirrors on wardrobes. The new ring needs to be bolted or clamped to the tube. A type of Wilcox ring but more involved.
One ring at the focuser end would do it I think? Won't know til I build it.
Raymo's idea looks good too, might do a combo of the two.
