Yes, duly noted. I expect a 3/8 heliocil tool to be close enough to work on the M10. The real appeal of that kit is the M!0-1.0 STI tap. We don't have one and to source it from somewhere in the US would probably be twice that of the China kit.
I thought about having one of the insert's I made turned down but the reason I went with .500 OD was because we have .001 under reams. I expect I could safely turn down one of the inserts I made to .440-.450 but getting a press fit hole with just a drill is hit or miss, loctite can only do so much.
Ironically, the guy who owns the bike is a fabricator and lays down beautiful TIG welds but the paint on the frame is pristine and we are hoping to not have to heat the frame destroying the factory paint.
