Let's say, for example, I had an old vehicle that I wanted to let sit
in the driveway and use as a backup generator (12VDC power
available). Nice that it already has a self-contained powerplant,
with a good emissions control system.

Let's say also that I wanted it to provide 1 kW of power, at 110 V.

Let's also say that I wanted to power inductive loads with it: an
electric saw, etc.

So, how would I go about building one of these puppies?

I know that the cheap square wave inverters from Wal-Mart would blow
up if I tried to run an inductive load off them.

Any suggestions? (posts to old Masters' Theses, etc?)

I still have the one I built. used a 555, some Mosfets, the core of an old
torroid variac, and thats about it. Not quite 1KW, maybe 600 watts.

The mosfets didn't fry themselves when they saw an inductive load...?
