[PSUBS-MAILIST] o-ring groove

[hank pronk via Personal_Submersibles]

Brian,Did you sort out the boring bar for cutting inside o-ring grooves?   I need to do the same and could use some advice, I was going to make a boring bar cutter with a very narrow cutter, narrower than the required groove and do multiple cuts.  I tried to make a groove cutter that was the full groove width but it was to much.   Hank
