Re: Milling procedure confirmation

Yes and no, usually they are not " true" hss, but "only" so-called powder hss(some say they are much better than "real" thing).

Re: Review of WNY Phase Converter Panel

Nice job.

You can find vfd with a 1 PH in and 3 PH out, but they are usually smaller units - I newer saw(second hand) one bigger than 3kW(4HP).

Re: Good, cheap, material to practice with?

POM is pleasant to machine, but nowhere near cheap... Modern butchers blocks(thick cutting boards made of polypropylene or - most often - polyethylene) are not so pricey, but nothing beats DIY machinist wax.
