I know that it is a sign of mental illness, but I'm a sucker for old orphaned tools. Picked up a Slocum micrometer with patent dates of May 12th, 1890 and April 13th 1897. On the barrel it has the standard divisions for tenths BUT under that scale there is another that breaks the inch into eight major divisions, with each of those broken into 4 divisions (1/32nd). I'm unfamiliar with anything that would use that form of division / measurement. Any sage and worldly gunsmiths / machinists that know what this was used for? Built in fractional measurements?
Yeah.. kept playing with it... major increment X4, add the number of dividing lines for a measurement in 32nd's, easy math. Perhaps for providing measurements to those lowly carpenters who must have been tickled to get a measurement of 23/32nd's.
Ha! Wo needs decimal equivalent charts anyway....225010
