I recently made a small CNC mill and I've been having a lot of fun with it. So for my next challenge, I want to make a model of the planetary gearsets that can be found in a typical 4 speed automatic transmission. I can make *almost* all of the parts. I can use CAMBAM to draw the gears that have the teeth on the outside, but I need 1 gear that has the teeth on the inside.
So I'm wondering if some kind soul out there that has the appropriate software could sent me a drawing of the gear I need in dxf format.
The specs are:
diametral pitch: 12
6" in diameter
20 degree pressure angle
teeth are facing toward the center of the gear
teeth are straight (not helical)
