[QUOTE="Mikecr, post: 432837, member: 1521"] You got it. And more than that, if you're comparing bearing surface or nose trimming, you need to first qualify those datums. I'm proposing a revision to Bob's design that would allow for a reasonably priced 'kit' to cover multiple cals. His device is analogous to a Kevin Cram nose trimmer body, with a sliding internal bullet seater plug, that is indicated. I built one like this, the moment I noticed that nose trimming doesn't always leave meplats at the same diameter. But Bob's a better machinist than me, so he get's my business. A kit would consist of swappable datum plates and seaters for a single body and indicator. That body should also be adapted to a stand. He should be able to knock these out in cheaper numbers(if he's interested). [/QUOTE]
