I started on the frame that holds the main drive last night. I had the original piece the big harmonic drive mounted to as well as some of the aluminum for the base. It is all 1/2" aluminum. Finished up that part tonight. The plates have bores for bearings and curved slots for the angle adjustment. It will got up to 60degrees of tilt. I am still working out the design of the base section, I have got a good idea what I want to do, just not sure.
I might send some of the parts out for bead blasting and anodizing.
