Hi,

Nice catch on the surface grinder.

As for swapping out its current motor, I would be VERY hesitant on
doing that. Any surface grinder worth having has a balanced
(expensive) drive motor. Any old DC motor will not be balanced and you
will be setting yourself up for alot of hair pulling trying to figure
out what is wrong with your finish. Experience speaking here...

If you do finally put a suitable DC motor on the grinder, pay
attention to the no load RPM of the motor you use. We wouldn't want
you or your new grinder scratched with an exploding wheel when the
motor exceeds the RPM rating on the wheel in a no load situation.

Good luck with the effort and keep us informed as to the CNC effort.

Sorry about that Mark. I've been watching, kinda casually, for benchtop SGs
on eBay, and they all seem to go for way more than I'm willing to spend,
typically in the $800 - $900 range.

So when I saw this one with a BuyItNow of $350.00, I couldn't resist.
Reading the archives, though, this seems to be slightly on the high side
for _private_ deals of a couple of years ago. itseems like eBay has run up
the prices on these things a whole bunch.

I wasn't TOO worried about finding a place for it ( until last night ). You
see, I have one corner (by the stairs), where the hydraulic press sits.
I've been planning on moving the press anyway, and so I though this was a
perfect item to go in its place.

But then last night, I found another Sanford on eBay (for $800) with a bunch
of pictures. For the first time, I saw the back of a Sanford .. and
there's a motor sticking out !

Now, of course there would be, but I just wasn't thinking about that. This
motor sticking out in this corner would effectively block the stairs.

So, I may be adding a fourth motor to go along with the three "CNC" motors.

That fourth motor will likely be a DC motor ('cuz they're smaller for the
same power) mounted _above_ the spindle pointing forwards (where I can bang
my head on it) with a belt running down to a pulley located more or less
where the original motor lives.

Or I may just punch a hole in the wall ( a slot, really ) and build a little
weatherproof box around it.

But I WILL find room for it .. sorry.

Oh, Alan, you beat me to it! So where's it going? Gonna move a

Or, my (first) marriage survived a Porsche engine under the bed for
a few months - perhaps move something into *her* ("our") living space?
Having witnessed the pain you went through disposing of those compressor
parts, I don't really see you actually SELLING anything...

I rather liked my line - borrowed from a friend of Guy Lautard - "A
lathe followed me home and I think I'll keep it....."
