Hi Mick,I am doing the boring on my lathe. Don't have a boring head for my mill/drill. I use a telescoping gage and a micrometer to measure the ID of the hole that I am boring. I am getting better at it. I now get consistent measurements. My measurements are smaller than the actual ID. How do I know this? As stated in a previous post my measurement of the ID of the hole is smaller than my measurement of the OD of the post yet the holder fits on the post. So the ID has to be bigger than my measurement.
Try doing it the old fashioned way with inside calipers and a micrometer.
