Practical Machinist is pretty awesome, I also pop into Garage Journal (Garagejournal.com). Also https://www.youtube.com/user/oxtoolco and

Also the Popular Mechanics and Popular Science archives at google books -

I can't believe how many hours I've wasted there on purpose, and by accident.
I haven't looked at the Popular Mechanics/Science stuff before. Just never got around to googling it up. Thanks for the links. Good to know they've got it all archived.
Yep, Tubalcain is wonderfully curmudgeonly! Been meaning to get back to Ox some more. Don't know him well but looks like a very skilled dude. Also spent many an hour in awe of Keith Fenner. One of these days I'll figure out how to download YouTube vids and save them. I hate to think of this stuff blinking out of existence.
Yes you can use a vfd as a phase converter. The output will be 3 phase 240 V
Right on, Dude. I gambled with a $100 bid at auction yesterday and came home with a 22kw rated unit. Literature advised 3 phase input required, so I figured at the very least I'd have a nice controller between the generator and milling machine, but was hopeful it would open doors for me with single phase domestic supply.
If you wanted to be able to run it off domestic supply or 3-ph generator (I don't even know what the mill out there will draw but it's going to be at least 10 kw, so I figure I might have to feed that with the genny), would you just put a 3 phase male plug on the VFD and then adapt a single phase extension cord with a 3 phase female plug, then swap to the generator's 3 phase cord when needed?
The manual is talking about the importance of grounding, earth leakage, etc. I don't plan to remain clueless but I am at the moment so want to make sure grounding needs would be accommodated with a single phase cord's ground. Also not sure if a male plug on the VFD would be really dumb if capacitors can discharge back through the supply plug and kill me. I could opt to just hardwire, forget about putting the generator through the VFD (or this particular VFD), if plugging in invites disaster.
