I'm getting the idea that $30 is a bargain.

i consult for a granite and marble place here in MI. i strongly suggest
you walk into a local facility that does stone countertop fabrication
and ask for a scrap before you pay for a piece of stone.
our company pays $150 per day to discard tons of large, flat "scrap"
pieces. so much material, in fact, that i am seriously considering
building a large router table out of 2 1/4" thick granite.
good luck,

Pardon the newbie question, but what are the main uses/benefits of a granite
reference plate?
The size of plate you are talking about in this thread seems too small to
lap planes. All the scary sharp fans seem to go for a large piece of glass
as backing for the sandpaper. I googled granite reference plates and see
there are many sizes and "grades", but not much about the main uses a
woodworker would make out of having one. Any feedback is appreciated. I have
already learned LOTS by lurking on this NG for a few months. Regards,

Nowhere close. It may not matter though. Depends on what you are doing with
it Are you using this as a measuring standard? If so, go with surface plate.
Are you using this for sharpening? if so, go with the cheap stuff.

Even better, judging by the thickness, or lack thereof, they are definitely
*not* surface plates.
Those suckers are *thick*, like 3 or 4 inches for small surface plate.
Still, really nice pieces of granite, and a nice shop, to boot.

If you take two plates, spread some rubbing/polishing compound between them
and slide one over the other, they'll polish out to flat (or spherical, one or the
other). By working with successively finer compounds, you'll be able to get
any degree of flatness and smoothness you want. Trade off cost vs work.

I got a scrap granite piece about 12"X18" that gets used for scary
sharp. Got it during our kitchen redo.

you need 3 plates to make it flat. with only 2 plates you can make one match
the other, but they won't be flat.

Judging by the reflections on those surfaces they are just a couple of
granite slabs - the type that you would use for a countertop. Not the type
that is flat to the 1/1000". Still they are rather flat.

shipping may be too much with MSC. so far grizzly has the best shipping rates on
surface plates.

Hopefully, they'll ship that big piece of granite for $6 or less, otherwise
you'll be better off getting it at Woodcraft.

Dunno if it's a good price either, and I don't know how hard it is to come
by stuff flat to 0.0001"
I'm gearing up for Scarey Sharp, and I'm using a lot of chunks of what I
think are granite counter backstop. Happens to be the right width for
pre-cut 1/3 sheet sandpaper. It's as flat as my straight edge, however
flat that is, and it was free. Dumpster behind a custom stone counter
place. They throw away about four cubic feet of this stuff every day.
I'm heading that way tomorrow, to see if I can get enough chunks that I can
have one dedicated chunk for each grit.
Want some? :)

I've thought of this. Is the flatness of counters comparable to reference
plates??

If you do this with two plates, you'll get spherical surfaces, guaranteed.
If you do it with three, you'll eventually get three flat plates.

Hmmm...$30 or hours of rubbing two stones together, plus polishing compounds
of various "grit". I guess if you want to make a point that it can be done
you could go this way.

Ten years ago you would have paid over $100.00 for one. What do you think?
