Today with a little spare time brought me to looking at the dial on the knee of my mill. One rotation of
the knee crank moves the table up slightly less than 100 thousandths. The dial goes from zero to 3.0
in 150 marks on a circumfence or put another way each division is two tenths of something. The marks
have no correlation to inches or millimeters as far as I can tell. There must be more to this than I see
but it is a mystery to me. Tthe X and Y dials are calibrated in thousandths increments and I bought the
mill new so the dial has not been replaced. I'm hoping someone in HM land knows the answer.
