It's pinched on a string, and the diameter is read from the dial. That's a 0.051" core and 0.253" wrap in the photos. This is about the quickest and easiest thing I've come up with so far for taking scale diameters. Frank's caliper input toy sounds like fun, if I can set it up, and if the calipers are that trustworthy. The cheap digital calipers are terrific for woodwork, and most of the metalwork that I need, but I'm not repeatable enough measuring strings with it to trust it. Holding it toward the points, like I do with the snap gage, rather than at the thumb "wheel" helps, but it's still awkward for me.
