Thank you for the great responses! I'll throw a few more questions out
there since the list has been so helpful.
-I've seen museums use round belts that look like plastic string. I can see
an obvious advantage of using this belt to provide a reliable slip clutch
for overzealous visitors. Any thoughts on this?
-And speaking of slip clutches, do you usually recommend a friction clutch
from McMaster, or is there a better alternative for hand-cranked
applications?
This gives me a great start. Thanks!
-Eric
