Benchtop? Er, small stand-mounted model would do. Is there anything
decent and frugal?

Good grinders are usually not very expensive at liquidations and
such. Expect to pay perhaps $50 (on a bad day) for a Baldor 1/2 HP
grinder, smooth as silk.

Surface grinder with a bed, not the wheel grinders. Already have one of
those.

Doubt it. The smallest one I've ever seen was small, about 1.5 ft
wide by 2.5 ft long, but it had an integral base. It wouldn't take up
much more room than a small stand model, though. I know it's older,
dunno the exact model or manufacturer.

Hmm, the game's afoot, Mr. Holmes!

The lesser expensive models I've seen have been in the 2K range.

Searching ebuy for surface grinder. Here's one in Wisconsin, but I think
it would probably collapse the steps down into the basement, plus it's
230v/3PH.

So figure another $200 for a VFD to power it. You do not want to
consider replacing the three phase motor with a single phase one as it's
been reported that they don't run as smoothly as three phase and will
create defects in the ground finish.

Horrid fright and grizzly seem to carry the same surface grinder from
central machinery. No coolant channels. Looks to be dry grinding only.

Yup, 155v. Everything is a little bigger here in Wisconsin.

Yes, though if you actually have 155V you've got a bit of a problem
there. The VFD normally expects 200-240V input, and yes single phase in
and three phase out. Visit http://www.driveswarehouse.com to look at
some.

Something like that, though normally the input and output voltages are
the same. Most drives are 240V input (or like 200-240V input), 115V
input is not very common.

That's either too high for the ~115V or too low for the ~230V part of
your service. Either way, it's well out of spec for US utility
standards.

Pete C.

PS: I'm in TX where everything is indeed bigger, and we still have
pretty close to the expected ~115/230V service. My UPS reports 119V at
the moment.

Uh, SARCASM:ON The 115v in my house is standard. I was being cheeky
about typing 155 instead of 115.

Thanks for the link.

1 HP 208/220 3 PHASE 2.8 AMPS

The FM50 shows 4.2 and I assume "Full Load Amps"

I _think_ the Clausing is rated 2HP / 230v

According to Louis Ohland :

decent and frugal?

Yes -- if you don't insist on the company still being around.

Look into the Sanford line of surface grinders. The smallest of
them can be used as benchtop machines, as I use mine.

But apparently the company went under shortly after I got my
manual from them. (The machine was quite old, and needed a bit of
modernization of the power supply for the electro-mag chuck.

Enjoy,
