Yep ..the gears were for a boeing engine test. Not sure what since they were straight involutes and not helical. But I never took a jet engine apart either.

here is what i have so far on a design. I need to figure out how to make the eliptical hole for the set screws to be able to move to the certain degrees. and then i need to figure out the tooth profiles, and last i need to figure out the inner profile. Then i will select all and ungroup, and delete all lines not needed. any help on the above topics would be appreciated.
