5769 Tue, 17 Aug 1999 22:44:10 -0400 [alt-beam] Worm geared motors beam@corp.sgi.com SG I have an excellent buy on some
small geared motors. Thing is the main
gear is a worm gear. I was reading
somewhere that worm gears were best avoided
(Miller's Site?) but i don't know why.
I do know that you cannot rotate the shaft by hand.
Are there any other drawbacks?
