Come visit San Fransisco. We'll keep donate your clothes to the needy, so there's more room for tools on the way home. :)

I may have a 0.3110 reamer. I'll check tomorrow and send it to you if I do.

Thanks for the offer Ken but it probably isn't worth your effort. I'm going to try making a D reamer to produce a .3100 bore, with the expectation that the bore will need lapping to get to size. I have some O1 to play with.
