I am helping a friend sell some cues. I am almost ready to post them but I need to figure out the shaft diameter. Can somebody help me with the proper way to do this and what tool to use?
Tool used to measure shaft diameter?

Most accurate is with a pair of calipers. If you have a soft tape measure with a mm scale you could measure the circumference and do some math, butting might not be quite as accurate.
Use this http://en.wikipedia.org/wiki/Caliper
I think this was a pretty usable brand http://www.ebay.com/itm/6-Inch-150m...699?pt=LH_DefaultDomain_0&hash=item53f88ae4e3
The measurements you want are at the tip/ferrule and at the joint base. Need to weigh it also.

I have a digital micrometer that I use daily on my CNC...Very accurate but at over $100.00 it might be overkill. Those listed in the ebay add are similar to mine. At that price you can't go wrong.
Micrometer is very accurate, actually I think micrometer and calipers (like the ones I linked) are just about the same product, you are paying for a fraction of a mm accuracy once you get past the $20 range, which you don't really need to measure a cue tip for selling.
OR you could go the really cheap alternative and just get one of these....

for less than $20 at any hardware store. Mine is a Hempe brand; accurate to within 1/3 mm (1/64th inch).
The digital calipers commonly available on Ebay and in the automotive and hardware store work great. Generally you can get them cheaper online, like Ebay etc.
As for the jaws...yeah, those metal jaws with sharp edges are an accident waiting to happen. One could easily scratch/gouge a ferrule or shaft. But no worries. If you have metal jaws just cover them with electrical tape and calibrate with the tape on. Just push the button to calibrate. Of course, compression of the soft tape introduces error, but in terms of the tolerances we are talking about for these purposes I think it is negligible.

say what you will but years ago this is all that was used and as far asI know measurments have never changed IMHO
Thanks for all the replies.
rcbs makes a fiber glass caliber I have use for reloading rifle and pistol measure the cases length but you can buy a tip gauge I seen one at a tournament the other week if you use a metal caliber put some tape on the end so it won't scratch the wood
