Maybe OT - cutting granite

Got a nice piece of granite (1 3/4") to use as my bas for sandpaper
sharpening system, but I need to square it up.

How do I cut granite? Is it time to find a counter top guy who has a diamond
blade or what?

Thanks for the suggestions....

You need a diamond wet saw to cut your granite. Most tile installers and
many stores have one for cutting tiles, including granite tiles. A local
installer or store may be willing to cut your granite for a fee.

I'd be inclined to visit a local headstone shop, but if the angle
grinder idea has appeal, then something like the fifth and sixth photos
from the top at

might work as a holder to run along a straight edge.

You already have a flat surface and now you mean to cut the edges
square, no?

A friend of mine cuts granite using a hand-held circular saw with a special
blade, runs water over the cut to keep things cool, and has a GFI on the
power source for the saw. I'd want pneumatics for this, but he makes nice
cuts, and is still among us.

You can make small cuts in granite with an electric grinder and a suitable
disk. Difficult to be accurate, the finish will be rough and I would never
attempt to smooth or polish even a small piece of edge with ordinary
abrasives.

I'm a bit late to the party. Use a diamond masonry blade in your
circular saw. A low-cost one will do fine.
Clamp on a fence, and take 1/4" passes. Dry. And reasonably quickly.
Outside with goggles and dust mask, stay up-wind, because it gets some
dusty.
I do this all the time.

You might want to take a look at
http://www.gardengatemagazine.com/extras/76cuttingstone.php which has a
couple of nice videos that show how to cut stone with a hammer and chisel
and with a diamond saw.

i cut lots of granite slab using an angle grinder with a 4" dry diamond
blade, if it's too large to fit on the table of my tile saw. don't breath
the dust, btw. if you want a polished edge, you need a water-feed
grinder/polisher. i use this one:

http://www.contractorsdirect.com/Alpha-VSP-120-Wet-Variable-Speed-Wet-Polisher

depending upon the size, just find a tile guy. home depot will cut it for
you for not very much/cut.

That is correct. It is a piece of counter top that broke in transit. If I
can square it up it would be cool.

That is kind of what I figured, just hoping for a solution I could do in my
shop.

Some years back it got me a new ("mud job") tub surround by one of the
best tile guys in the area. ;-)

Wet saws aren't all that expensive and are useful things to have
around. I bought one a few years back for tile and have used it quite
a bit. HarborFreight has a fairly nice one for what I paid for mine
($250ish).

A case of beer might get an installer to cut it for you. He might
even share. ;-)

Ir a diamond blade in an old circular saw. Use a hose to wet down the
granite. Not too wet though (electricity and water don't mix well).

Those guys use water jets with grit.

Might talk to a grave stone company in town - they might be helpful experts.

You can get inexpensive diamond blades for angle grinders. Maybe rig up
some sort of carriage to hold the grinder and ride along a straightedge?
Should be good enough for shop use.
