The thread mill is very impressive. Have you tried it yet? How do the threads come out? I make a bunch of parts and have been tapping the 12. npt holes by hand .... labor intensive to say the least. I've shopped around for a threading bar or indexable cutter but without trying them out I'm hesitant to spend the $80-$350 .... you may have solved my problem.
No ideas what to do with your last blank .... but I'm sure something will come up
