[QUOTE="Trickymissfit, post: 511370, member: 25383"] if your talking a gun barrel of any real length it's a pain in the butt. We used a few gauges that read a laser beam, and also the basic probe which reads air flow around it as it moves thru the bore (these are good for about .00015"). This is mostly for size, but will also show you a drift in the bore or out of roundness. I also built gauging complexes that would check every spec on the part including concentricity. Many of these used electronic probes that never actually touch the part. These things are good for less than .0001" variation. But the best one I ever saw in use was a simple ultra sound setup used in a military ap. I thought it was a joke at first, but soon learned it was very reliable and also very quick. All it did was measure wall thickness on a given sized O.D. We used that one on the biggest gun of them all (65") gary [/QUOTE]
