I cheated I used the old gear to align the cutter with, I know its probably off some but for what the gear does and the wear on the worm that it mates with it should fit ok.
Math isn't one of my smartest points, so if would of had to of actually figured it out I would probably still be in there trying to get things aligned. It actually would be a lot easier to do with a Horizontal mill, then all you would have to do it set the index head at an angle and fine the center of the teeth.
Now if I can find the 4MM broach to cut the keyway with, I'll be pretty much set.
And the original gear was probably metric but the 20 degree cutter fit the old gear perfect plus I've used it to cut other gears for the lathe with.
I also put in some time on the highwall today. I have just about finished blending all the joint on the bottom of the action so that I can start in with the sand paper.
now to pull it apart so I can file one tiny spot where the thumb pad hits the action making it hard to cock.
