a friend has squired a piece of 3/4″ granite counter just large enough to cover a small base cabinet. unfortunately, no fabricate within a days drive want to stop production to cut one piece to size.
can this job be accomplished with a ski saw and the right blade? how would it be polished after? are there perhaps methods of breaking a relatively straight edge then polishing down the highest edges?
thanks to all who take so much time to answer the questions here, your time and knowledge is greatly appreciated.

I have only cut granite using a gas powered "quick-cut" (made by Stihl, or um... Husky) and a dry-cut diamond blade made to handle granite. This set-up you can most likely rent, just make sure you tell 'em you're cutting granite, as an ill-suited diamond blade may get damaged or worn too quickly (the rental co. will charge you by how much the blade has been worn down).
When cutting, make sure the saw stays dead straight or the blade will bind. I don't know about polishing, as I have only done outdoor work (patios, walks, walls, etc)
P.S. I don't think a skil-saw will have enough grunt to do granite, but if it is only 3/4" thick you might get away with it, assuming you can find a proper blade for it (it's probably cheapest to rent the above-mentioned gas powered set-up).
*b WBA At Your ServiceA typical circular saw with a quality diamond blade will make the cut. Clamp a straightedge on the granite and cut away. Polishing can be done with a decent belt sander and silicon carbide sanding belts. Patience is the key to the process. No, you cannot split the slab and achieve the desired results.
*Ditto Tim...I'd also recommend supporting the slab completely (scrap section of ply) while you cut it. You may want to make the cut in more than one pass. Have your blade depth set so the last cut scores the ply.It may be too tough for you to get the edges to a high-gloss polished finish. If you need all six sides to match, consider taking the entire slab down to a honed finish.
*u can use skilsaw,,, its smooth cuts,, hee hee just kidding
*I really need to check the spelling ..thanks for the reply was planning on the straight edge.how far through the slab on my final pass should the blade run?thanks again, mark
*b WBA At Your Servicenot sure i understand your question, also not sure it matters. as long as the blade is deep enough to fully cut the material, it is deep enough....
*You might try the local rockhound club to see if they have a saw that can cut the slab. Polishing is difficult, the post about using silicon carbide is probably the best answer. It works better wet, but that may be a problem with your equipment. The final polish is usually done with leather and cerium oxide or aluminum oxide. I only do this on a small scale and don't know how the commercial outfits do it for large areas.Erich
