RE: Propellers
The SAE hasn't released the official rules for this year, so I can't guarantee which engine will be used. But I'm guessing that an OS 65, or something close, will be used. Also, several people mention machining the propeller out of wood; does anyone have instructions for doing that? For instance, if we were to make our propeller out of Maple, what kind of bit would we use on our CNCmachine to cut it? Currently, Ithink all of our tooling is made for machining metal instead of wood, so we don't have a great deal of experience with wood. Also, once the propeller is machined, how should it be finished? As in, what kind of sanding, sealing, etc needs to be done?
