Gears are expensive. Why not make your own?
I'm figuring out how to do it on my CNC. Hopefully I'll have some pretty convincing gears by the end of the summer.
Plus, remember, once I figure out how to make gears, i can make them out of most any material i want (aluminum, titanium, UHMW, lexan
)
So i'll report back on CD sometime when i get a convincing gear and probably post a whitepaper and pictures on how to do it.
