A dumb usage question now that I have this thing installed. It just occurred to me.. rather than the usual take a fine feed skim cut with gib locked, measure the cut surface with a micrometer, zero the dial business...
If I were to chuck a nice, shiny piece of hardened drill pin I have handy, make tool contact to the pin, then enter the known pin diameter value into the DRO, would that not be a more accurate way of pre-setup prior to machining assuming the DRO is doing its job & measuring accurately through the range? That way I should be able to chuck up any rough stock & work my way down to (something very close to) finish OD assuming I keep the same tool in place, no? Or is it still good practice to measure prior to that last fateful cut?
