the simplest way to measure the helix angle is to mount the gear onto a hobbing machine and to change the gears
on the lead side and use a dial stand to get a "zero reading" when the machine is traverssed.
It does take a little time to do it as you would have to keep changing gears but when you have to duplicate a helical gear which is modified we have found this to be the best error free method.
We would normally load the gear to be checked onto the machine and check it, and immediately load the gear to be hobbed so as to save further set up times.
