Chad Bridgewater is one of our grad students in Metals at UWM. He was active with the DCR&D group this summer and is continuing his own work this semester. Chad just finished building a turntable for doing some large 3D scans. Nothing like being resourceful. Check out his blog for more of his projects.
I used a drive shaft from a 1981 Suzuki 650, some angle iron and other scrap sitting around. I spent no money and just picked from my inventory of stuff. You can use a drill or turn by hand with no more effort than twisting a screwdriver.
