I am looking to get a couple of sets of custom joint protectors from Jim Baxter for my custom cue which has a 3/8x10 pin but the problem is I need to convert the joint diameter into thousands of an inch.

I have tried googling this but the results are double dutch to me, so any in converting would be greatly appreciated as I really am lost.
 
3/8 is the size of the pin, I think he wants the diameter of the outside of the cue at the joint.

3/8 is .375 inches if that's really what you mean.

Sorry angldemn I know trying to but I am completely lost & haven't a clue, here is part of his email if it helps:

"I would need the joint diameter of the cue in thousandths of an inch."

This is the measurement he needs.
You will need to get some calipers to measure it accurately.

As your second post indicates, Jim wants to know the diameter of the joint, not the pin diameter. To get this without calipers, take the butt of the cue and stand it on the joint end on a piece of paper. Trace around the circumference of the joint onto the paper. I suggest using a sharp old fashioned wooden pencil--if you use a mechanical pencil you risk scratching the joint collar. Trace the diameter as close to the joint collar as possible; you should angle the pencil point in a bit. Measure the inside of this circle with a ruler, then convert to thousandths.

Using this method will likely produce a measurement that is slightly large, but many joint protectors are slightly outsize anyway, so it shouldn't matter.

This one wins the pun of the Month award.

For the price of a set of dial calipers, you should purchase a pair.
Even the digital ones that will convert thousandths to MM are very inexpensive.

If you are going to purchase a few cues here and there you will find a pair of calipers to be a handy tool. They will hep you out should you decide to buy extra shafts for your cue in the future also.

Jim wants the joint diameter so he can make a precise fit for you set of JPs.
