I didn't, based on Huntress' suggestion that the tap burners he used
were run in air. Might try that sometime, but found a commercial edm
shop nearby with a $75 hourly rate that said they could do it in under
an hour, so we'll see. Definitely cheaper than all those caps,
transformers, etc., even surplus.

I am going to invest in a hand tapping machine, though. Well worth
it.
