Need information on composite spline plug gages
(OP)
I have a spline that needs a go composite spline plug gage made for it. Are there formulas to calculate the gage dimensions out there somewhere?

The SAE spline system uses the same "basic" tooth thickness for all classes. This is pi/pitch/2. A plug gage checks space width, ans is made so that, when worn to usefull life, would be size to size in a minimum internal spline.
The detail tolerances are in ANSI B92.1-1970, but you don't really need them unless you are inspecting gages. Ordering to that spec will get you what you need.
