First, thanks everyone for the generator info. Looking into the cost,
I started to wonder if it really would be cheaper overall than
replacing the power hand tools down under. It probably really is,
considering some of the power tools I would take I've had some 10-15
years and still haven't used once. If I only replaced the hand drills
and grinders, maybe not.

But... I've been told several times that AC brush motors run fine on
50hz, just a bit slower. I took a good hard look around, and the only
110v AC items I have in the shop (outside of my nice shop stereo) is a
vacuum pump, my Baldor, and two bench grinders. The Baldor is not
rated 50hz, and it was mentioned here some time back in response to
other questions of mine, that induction motors will overheat on 50hz.
But if I'm only running it for a maximum of a couple minutes at a
time, generally only around 30 seconds (and only maybe a dozen times a
month), it would seem to me that the motor is likely to last the
remaining 15-20 years I think I'm going to be active.

I'm not too worried about the bench grinders, worse come to worse,
easy enough to make something up with pillow block bearings and a 50hz
motor.


Thanks,

Jon
If the motor runs too hot to suit you just reduce the voltage to that
which gives the rated current draw.
That may reduce the power but if its a small reduction you may still use
the motor.

You would have to reduce it to 100 volts, from 120. That reduces the
current, as well.
