Gear Tooth Profile Template

[brakemeister]

I need to check the profile of the tooth surface of a 52 tooth, 17 NDP, 20 degree PA molded plastic gear. Does anyone know of templates which may be available to use on an optical comparator or, perhaps, of a better way to measure the gear tooth profile?

are you going to use a 100 or 50 times
size comparator?
