I missed the fact that you're using an inside mic. I have a couple

that style, but rarely use them. For this sort of thing I'm more

telescoping gauge gives a better feel than the inside mics and makes
a
direct comparison between the bearing and bore easier.

Thanks. I've had trouble with telescoping gauges previously, probably
because I didn't have a rigid enough boring bar to get a smooth
finish. I just measured the inside mike's setting ring with one and
hit 1.0000" on the first try.
