Will this work?

I'm building a paver patio and I need to cut some wall stone and pavers. Not a huge amount, but I'll probably spend a total of 2 days just cutting. I have a radial arm saw that I just don't use anymore since I have a miter saw. Can I use the radial saw as a dry saw? I'm thinking of getting a diamond blade. I just don't want to tear up the saw unecessarily, will the dust mess it up? I have an air hose so I can keep the dust buildup down. It's a Craftsman 10" saw, I forget the motor size, but it was one of their more powerful saws. Will this saw stand up to this? I don't really want to buy another saw for a one time project, and I probably won't have time to do the cutting all at once so renting a saw would be expensive.
 
id get a abrasive blade for the saw and be real sure to wear a mask and goggles at least, resperator would be better, your body will thank you
 
What kind of wall stone ? Is it already cut in rectangular shapes , or random as per your design layout?

Do you think it to be feasible to hold random shapes in a safe manner against fence ?

It would probably work, I would keep an air hose handy and blow out the motor often to keep rock dust from destroying the bearings.

I wouldn't try to take it all in one bite either maybe an inch at a time keeping the heat away from arbor as much as possible.
 
I used an old radial saw to cut all of the landscaping stones around our house. I bought a diamond blade and used a shop vac as a dust collector. It worked fine and didn"t seem to wear the saw.
 
I cut a dozen or so hard red bricks with 1/16 abrasive metal cutoff wheels and 4 1/2 in grinder. Ate the wheels up but was quick and easy.
 
20 years ago, I put 20,000+ clay bricks on my house. They were hard as steel. Used a 10 in craftman's radial, only had an 8 in diamond blade, GFI and sprayed water on the blade. Pushed the blade into the brick. Replaced the deck of the saw with treated plywood. I had to cut half the brick at a time, saw is only 1.5 hp. Most brick saws are 3-5 hp. Take your time and wear ear protection. BTY, after I finished cutting all my brick, the set screw on the armature holding the governor/end switch in place came loose and smoked the field windings. I don't think much of radial arm saws. Would NEVER purchase another one. However they do make a great lawn mower blade sharpner if you put an 8 inch stone on it and they cut 12 in soffett well too. Almost never use mine to cut wood.
 
How thick is the material? I have a tile saw that I bought new for 20 bucks (cheaper than buying a blade seperate) and used it to cut 2 inch cement tiles (12"x12") for our frt porch. Done our Hof (driveway) with brick size pavers and used a diamond slotted disc on a 7" angle grinder for all the cutting. Think your RA saw would work fine, can you rig a shopvac to keep dust away from the motor?
OTH, renting (or buying cheap) a water bath cutter will be much quicker and easier on your lungs and the person cleaning up afterwards.

You will need to clean the shop vac after each cut. I agree, a wet saw is the way to go. An RA can be converted into a wet saw. Before I used up a shop vac, I would use a strong fan and blow the dust away. You sure don't to breath it.
 
2 days of cutting will trash the saw, then you will have to rent/ buy another saw to finish. Rent a wet saw or a chop saw (about $75 a day for saw and blade), use a diamond blade (rent this as well, they will have a good quality blade that will cut straight and quick), ear protection, and eye protection.

The biggest problems with a radial arm saw will be dust getting into the motor and heat on the blade which will warp it and dull it quickly. I"d be heistent to put water to a saw that was not designed for that use (shock or worse). I"ve used a 12" miter box when I need to make just a few cuts and it"s a chore.
