Making silencers means lots of concentric single point lathe threads; it is exceedingly helpful to have thread gauges that have been carefully made to spec and measured with the 3-wire method. Here's one for 5/8"-24 UNJ, class 3a.
Use it when making 30cal rifle cans. Can't see why tooling shouldn't be purty!
