mkk, 1.25 mod = roughly 20 DP. And I agree, 85* helix angle sounds as though it would look like a screw thread. Or a worm, then. Wonder almost if it could be 85* the other way 'round-- that is, 90* minus 85* = actually 5* helix angle.
Ron, what is a slew gear?
And Owen, sorry if I don't know. Sounds like Bill knows what is going on though.
