Acme thread gage

[Cole2534]

I'm looking for an acme thread pitch gage, leaf style. I have them for MM and UN and would like add an acme unit but neither Mit nor Starrett make them. The obvious answer then becomes that I'm looking for a unicorn item but I want a foolproof way to figure TPI of odd nuts.

Anyone seen one?

McMaster has one here -- but it may make your eyes water.

You can determine the pitch with a standard V pitch gauge.

...now I feel really dumb.

Woof, that is pricey.

There are several types being sold on AliExpress and cheap enough to try even if they don't work well.
