wire size

[pianotune05]

H Tom,
I'm going to research this micrometer.  Perhaps the numerals are larger.  That would be great.  My special glasses for really small things will come in handy as well.  Thanks again for the information.

    I'm curious, where would one see size 23 wire?

  I have used really thick pieces of wire for splicing broken bass strings on concert grands. Otherwise, it is very rare to see a #23 string.

  I was just reading on line about the Smith-Kettlewell micrometer which is recommended by a sight-impaired piano technician in San Francisco:


  "For general use in making precision measurements of mechanical dimensions.

  This is a standard mechanical micrometer which has been adapted with an expanded braille scale. The scale is on a drum whose diameter is larger than the "thimble" on which visual markings are inscribed.

  Can be used by blind machinists, automotive repair technicians, piano tuners, electronics and fabrications technicians, etc."

  Regards,
