Sanding with the manual tool continued. Other possibilities were explored such as buying or building a belt sander. The idea of building a belt sander that can attach to a power drill may be explored in the future. Obviously it would need some way to keep parts stationary to the drill, possible a second handle.
Until a different approach or tool can be found the manual sanding tool continued to be used. All of the smallest gears were sanded and probably took ten minutes each. This meant more than a minute was spent between pair of teeth and there are several hundred teeth. Not to mention the 500mm hardboard gears which are harder, dustier and have a lot of teeth.
Two of the 200mm gears were sanded as well. These teeth had much less curve than the 100mm gears so sanding was easier. These six gears represented a full day of project work.
