P.S. note the yellow mount how there is only one pillow block bearing for the RA at the bottom.
The drive disc is cradled and rides on a driven roller and a second free running support roller and this acts as the second bearing with the weight of the scope giving the need force to stop slippage.
The fork attaches directly to the drive disc with tension supports to stop the disc from warping.
Mine is based on this but bigger.
Not sure if you need portability but this would be possible.
The whole fork assemble will just lift off and slid out from the bottom bearing.
