Hi Netwolf
As to the time it took it was a couple hours each weekend over a few weeks my woodworking skills go back to year 10 which I have not used much in the past 35 years so if I could do dit anyone could, but I do have access to a CNC equiped sheetmetal workshop where the Aluminium brackets to hold the North & South bearings at the correct angle plus brackets for the rod and motor were folded at zero cost. The total cost abut $20 for some 12mm craftwood at Bunnings which was too thin for the project and had to be braced underneath with some timber scraps I had lying around, the dc gearhead motor and controller I've had sitting around for a couple of years another project that didn't get off the gound, I suppose it cost about $50 back then, the threaded rod a couple of bearings 2 pulleys and a belt came to $80 at smallparts.com.au and some $5 skate wheels. Now that I see how it works if I was to build another I would go for a welded aluminuim frame for the baseboard and groundboard, and would substitute the DC motor whith a stepper motor for accuracy and silence.
Thanks
Aprid
