A friend suggested I look into using a wet saw for tile & equip it with a diamond blade. Would there be enough rpm to make it work, or would it burn out motor? It's her saw & I don't want to ruin it. Thanks
I just started using my 10" tile saw for experimenting cutting. Keeping a rock stable seems to be the largest challenge. Use a rock vise if needed for straighter cuts. They are fairly cheap as are thin kerf blades. I started to break the surface tension of the water with some dish washer rinse. It makes water wetter.
You won't damage the saw. Any thing large is better done with a slab saw though. There is a place in town that has an 18" oil saw and I hear it's not too expensive for slab cuts.
A lot of rocks are as hard as a rock.
Thanks Hvacker. I live in SE MO. have been trying to find someone that could cut it for me, but so far no luck. Will try the smaller piece with tile saw.
I'm going to chime in with about the same thing Hacker said:
Tile saw with a thin blade and recirculating water system. About the only other thing you'll need is some sort of vise to anchor the piece in place. You will probably have figured it out however do use a blade large enough to do the job A lot of tile saws have a spring that snaps the blade back to upright after a cut so unless you want to hold the saw the whole time you can rig a weight to the handle that is just heavy enough to apply a light amount of force to the blade and let the machine drop thru the work. Just be careful and wear eye protection
Google "vice to hold rocks for slabbing" will come up with some clever home made devices that will keep your fingers safer.
One guy glues the rock to a board. OK.
Kat there are some amazing striations on the piece that broke off. I normally would leave it rough, but this piece will look dynamite when cut. I'd love to do a cab, but I think slabbing would show more of the beauty of the stone.
I use the water threwn off the blade as a guide for if I'm cutting straight. How large is to large depends on your saw.
A 10" is about fist sized ok, the rock shouldn't be higher then the blades height over the sawing table.
EU do I need to be aware of weakness in the striations? It looks like they are of different material. It's all new to me. I have always kept the material rough. I wish I could get a better pic of the piece. but here are a few more shots.
Just try cutting it and see. You'll know if they are weaker then the rest when the rock hits the blade.
It is often a good idea to use eye protection, though.
pretty sure that's petrified wood, same colors as what I find in AZ. you may find pockets of crystals, so go carefully. the striations are the wood pattern - are you going to cut across the grain or with it? (I'm hoping to start cutting soon, right now we're in collecting and waiting for retirement mode.)
