What is the best way to measure out of roundness? [Archive ...

The problem with ground stock is that it can be 'lobed' in a 3 or 5 lobe arrangement from the centerless grinding. This means that you can measure it in multiple places and see the same value but that the stock is out of round. The best way to detect this is to place it in 90 deg and 120 deg V block and measure the height while turning it - and the easiest way of doing that is to measure the work in a V micrometer.
