I got this at a garage sale for free. Are there any uses for it in Woodworking?
It's a 1-inch micrometer, by Millers Falls No. 701R.
I'm not really sure how to read the scale. The tube is graduated from 0 to 10, with 4 smaller ticks between each integer. So I assume that it is decimal inches.
But the thumb dial has 32 graduations. 1 full turn takes it between 1 small tick to another.
So each tick on the tube is then 1/4 of 1/10 of an inch? Than each tick on the thumb dial is 1/32 of 1/4 of 1/10 of an inch?
Does anyone know how to interpret these readings?
