I was wondering how well would a worm gear assembly hold up for AZ and EL drives and what
might be the drawbacks. I ran across one persons rotor project that uses worm gear boxes
with Nema 21 stepper motors. The gear boxes themselves cost about 45 dollars each and
appear to be quite rugged and waterproof.
