Hello Tornado,
yes, I took notice of diametrical pitch of 10 teeth over one inch. But as one can only put the Metric-Module into the involute gear module I made the gears with m=2.75 mm. I tried several different ms but somehow m=2.5 mm didn't look right for me...
German Wiki says that m=(25.4mm/DP).

When you saw the helical final drive gears I put on Grabcad, I first did these first with loft and then with Looooo's FC-Gear module. Wrote about it in the German Forum. viewtopic.php?f=13&t=12819

For the Final Drive Gears m=2.5 mm seemed alright for me, though.

Kind regards,
Helmut

What would interest me is where did you get the DP from? Any experience with designing gears like British Motor Corporation did it?
