Done! It was not fearsome, just took a while. About $800 worth of parts,
including a new motor shaft.

It's so quiet now, at 1500rpm, I can hold a normal conversation 4' from the
spindle without raising my voice at all. I can take a phone call while
standing at the machine. It's freakin' amazing!

I will document; for those with rigid-ram machines, this is something I
can't find good docs for anywhere, sans totally removing the head, which I
did not do.

Awesome!

Can you upload G code to this machine from a PC?

Yes. It's limited to 12K in memory at one time. Larger programs require
"drip feed", but that works nicely, too.

That's great!

Pretty much all you need.

Yeah, but I got a real plus out of this exercise I didn't expect.

Apparently, because of the belt wear and eccentricity of the pulleys in
the head, the spindle (not worn) was emulating an interrupted cut most of
the time. Surface finish was always pretty bad, and I'd trammed the head
as well as it could be.

Now the spindle runs smooth as silk, and the surface finish - with the
same facing cutter - is smooth as silk, too! Nice benefit for a couple
of days of grungy work.

A couple of days ?
