I was at Menards yesterday and was looking at saws. I saw a 14” cut off saw for $100.00. I was thinking, why you couldn’t/shouldn’t make a wet saw out of it and buy a diamond blade for it. How would it be if I got a tub to sit it in, and a small water pump to get water on the rock and blade? Can someone tell me the pros/cons of doing this with a 14” or a 10” cut off saw? Would a diamond concrete blade work?

the concrete blade will be a lot thicker. unless you are cutting expensive jewel type stones it should cut just fine it will probably leave a lot deeper scratches than a lapidary blade. it might cost a little for a pump but you could pump water with a statuary pump I guess I wouldn't worry if you didn't recycle the water or just hooked a hose to it and cut outside

A lot depends on RPM- I think either Doc or conrock were discussing this at one piont- To high of an rpm will just fling the collant off and provide little if any help- the risk ther is an overheated blade (Not a cheap venture) I can't remeber what the max RPM of the blade should be but It was pretty low.

Thanks alot. The rpm on that saw was 3700. The water pump I was thinking about was a 125gph pump. I might do some thinking on this....

Diamonds have to be run fast, however, with a cut off saw, the blade diameter runs faster in running length than a dremel bit. A certain MOHS recquires a certain speed. 125gph water flow? Dude, I would pay to see that in action! You will need to run consistant speed through out the cut, with the blade cooled by the water. A steady water drip with a lower bath might be in order. I would be more inclined to use a water bucket with two drip leads than a powered pump.

The rpm's of diamond blades differ with their manufacturer and also with different types and models within the same manufacturer. Here's a link to a diamond blade calculator. www.gravescompany.com/blade.htmIt may help you but make sure you know what the specific technical data is for "your" blade. Don't forget that the bigger the blade is the faster the outer diameter will turn.This is measured in "surface feet,and or, inches per minuet". You can change the speed by using different size pullies. Some slab saws have what is called "step pulleys" that are used for changing the speed of the blade and feed. A step pulley is a configuration of several different size pulleys made into one. Gotta go to bed now!! LOL Hope this helps,,,,,,,, Tom

A cut off saw is not designed to have water splashing around it. You get it in the motor and you are going to feel it! Also, I have been doing concrete work for 16 years and I have cut alot of concrete. concrete blades cost ALOT. I have used brand new ones that you hit a hard rock and all the teeth hit you in the legs. OUCH! And as thick as they are you would be loosing alot of material. How were you thinking of holding your rock firmly so it wont move? They have to be secured tightly. It moves and it can wipe out your blade. Personaly, it sounds too dangerous and costly.

The saw we looked at hade a smal clamp on it. I'm starting to think about spending more cash and getting one thats made for wet cutting. How good do the tile saws work? with a tile saw you are limited to the size of rocks pretty good, right?

I just got a tile saw and it will cut up to 2" pretty good- Holding the rock steady is a bit challanging and I'm still working on a clamp system- Or you can encase the rock in plaster (using a small pint sized milk container) and then Have a squared off chunk to work with- I love mine!

Earthdog, whatever you deside on doing, know that if the saw has a 10" blade it will only cut about 4 1/2" . I have a homemade 20" slab saw and it will cut some big monsters but, the downside of it is that once they get too small and I don't square the rock it become a problem cutting it. Lot of times they are still to big for my 6" trim saw.

Hey earthdog, when you say "perform", don't you mean Preform? As in cutting rocks?

Somehow, I can just imagine a picture, covered with rock dust, wearing a designer tinfoil hat, playing air guitar to Ozzy Fudd, strung out on critical angle, ISO, and singing harmony to MOHS. Like totally whoah!

Hey congrats on the saw- Same one as I got- I IM you a reply about the clamp- Oh and careful about your "preformances"- There are ladies on the board (I think ;D)

Yes, there are indeed ladies. In my opinion, very well versed in the love of the stone. They have class, honour, and can polish the pants off some of us rugged types. I cannot tell how many times one of our ladies has replied after spending real time researching. I am impressed with the depth of the reply. Dey got Moxie too.

I wonder what else everyone got for Valentines day, related to lapidary.... I didn't think I said anything outta line when I mentioned perform,(To take action in accordance with the requirements of; fulfill: perform one's contractual obligations.) If I did because of the many women here, I am sorry.

Well I know there are women here...and as I learned early on, all ladies are women but not all women are ladies. Me? not a lady...my mother...definitely a lady. However there are kids in this hobby and on this board too. So by performing behind closed doors, I assume you meant "with puppets"...right? ;D
