Thanks for all the help guys, but you are all looking at this backwards. I have traced a gear supplied by customer. I have to make a new one. I figured rough HA, pick gears close and played with gearing until dial indicator reads almost zero. Now I have a gear set, but still do not know what the HA is. How do I work backwards to find it, so I can put the data onto a drawing?
