Thread milling!!

Have to make a couple parts for a design project I'm working on. Last
minute change resulted in needing a bottom tap in a size I don't have
and it's too late to order from MSC. I'm hoping to have the parts done
over the weekend. So, ground up a broken 1/2-13 tap to leave a single
tooth, dug out the manual, played with it a bit, and viola! A perfect
thread in nylon. Now to see if my cheesy cutter will work in 6061...
