I'll try to add a photo, but the maquette has a 3/8" stainless steel shaft, with bearings at the top and bottom of the "sail" which rotates with the wind like a weather vane. The full size version will have a 5/8" shaft, and depending on the bearings available, I'll have to figure out how to mount and enclose them. My "machining" capability is limited to my angle grinder.
