May upscale a bit to accommodate my 12.5" as well as the 10" but mainly thinking just for the 10" at the moment. Probably need to put all the other projects on hold for a while to fit this in.

Hi Jeff,
Happy to help with any information you need. dimensions and angles are the hard part but it all comes together quite quickly once you start. Using a CAD software also helps to calculate dimensions as they all revolve around the angle determined by your latitude.
The drive shaft is 12mm solid steel rod with a bolt welded onto the end acting as a reducer to fit into the coupler of the standard EQ motor drive. This is temporary until a 12mm to 6mm flexible coupler arrives ordered from the net. Couldn't find any in Sydney. Once that arrives I will eliminate the bolt.
Cheers Greg
