My program gave me the following numbers (I have NOT gone through and hand checked these numbers):
RH Helical
Index 27/83 X 27/89
Feed 70/87 X 95/89 approx. feed .0322
LH Helical
Index 29/120 X 49/120
Feed 51/50 X 91/79 approx. feed .0440601
Both hands were calculated with a RH hob and conventional cutting method. I tried to avoid using gears over 100 teeth that did not seem standard.
