    A Dutch friend introduced me to a great micrometer for measuring string diameters. It is intended for measuring gear teeth, and is called a gear tooth disc micrometer. Available from machine shop discount supply. Msdiscounttool.com search disc micrometer.

    I didn't manage to put the photo in the body of the message with my phone - maybe I'll figure that out sometime. Here it is using the laptop.  Much less expensive than the Starett with the special thin anvil, about $60 as opposed to $300. Chinese import, but well made (if you want, you can spend $300 for the same thing). Also nice for felt thickness, as it has wider surfaces - use the friction knob for consistent results.

    Yes, the best style of micrometer for measuring piano wire in situ.

    That is truly a nifty micrometer, and I can see how handy it would be to own one.

    I just bought one, Fred. Thanks for the information. It can live in my stringing kit.
