That can measure the pitch diameter of a couple O'Donnell plugs?

Terry, It should be in the Machinery’s handbook. I can check in awhile. Or are you want some as built numbers as apposed to nominals.That can measure the pitch diameter of a couple O'Donnell plugs?

If you've got a regular 0-1 mic you should be able to pick up a fairly inexpensive set of thread measuring wires.
Terry if you need a /4 32 tap I have 1 for you.

Terry, hey might have a much of tools at the end of next week! After 44 years time to move on, maybe back to racing! There is different grades of taps and drill tap hole a couple thousands smaller so you get a 100 % threads most tap holes only get you 80%. If you have a thread grinder in your area, you can take a oversized tap and have them grind it down to what ever you want. I have seen that come in sets of three- rougher, semi finish and finish which end up a nice threaded hole. And as always use a lot of good fluid!
Terry, if I were going to order a custom tap I would seriously consider a roll form tap instead of a cut tap. JM2C

Terry,I've never used one, what's the deal with them? I've heard Brad recommend them too.
Ken,Wonder if a roll form tap would work on Titanium? Since that material is so hard and brittle??? Or Magnesium? Just thinking out loud... I always shied away from roll form taps. Didn't trust them to form threads/hole large enough. If I needed threads/hole to be tighter, just used a warn tap. Like I said...
Just thinking... Ken Wheeler
