??? Didn't you say you already basically ruined as a regular tap ???

Yeah, but it's my only one, and it's "sort of" working as a threading mill
right now. Just don't want to make it worse.

I started out with a 3/16" boring bar, Bob. It was too flexible, and just
sang to beat the band. The tap cuts quietly.

I'll try making up a LH boring bar, and cutting in climb.

You can always make a much bigger boring bar.
