Any one ever cut rock?

[Kershaw]

Wondering if anyone has tried to cut dry rock to make the bottom flat or to make shelve rocks? If so how?

I've cut the bottom off of pukani to make a stable flat surface to rest on the glass. I've also chiseled, drilled, and purposely dropped on the floor to see what kind of shapes I could make lol

I cut my Fiji Rock with my Gryphon bandsaw

I've cut rock using a bandsaw and a diamond tipped blade on a table saw. Both came out decent.

Ive dropped on concrete, and smacked with hammer and chisel! Both work, hammer more controlled.

I just got done cutting some pieces of regular "reef saver" rock with a sawzall and a 8" blade designed for metal. It left paint fragments but I gave a quick muriatic acid dip afterwards anyway.

Thanks for all the reply’s. I was thinking of using a tile saw or dimond cutting blade

I just used a fine tooth hack saw with water and it worked out really. As I cut my wife slowly poured water into the cut to clean out the blade flutes. Squared up about 100 lbs of rock on one blade, most reef “rock” isn’t very hard and it’s very porris.

This saw is much better than a hack saw: https://www.amazon.com/Buck-Brother...pID=41Ej6-9EjuL&preST=_SY300_QL70_&dpSrc=srch
Hack saws (and back saws) are limited with respect to how deep you can cut, but these have no such limits. You can even cut thin slices of stone with it.

I haven’t cut any. But I have used hammer, dropped it and used air chisel to shape or tunnel holes.

Why not just order some shelf rock? I got 10 lbs. of AquaMaxx dry Tonga shelf from Marine Depot and it is excellent rock.

Used a hammer and chisel to break a couple up pretty easily. Curing it now. After a 20:1 RO/DI:bleach soak and then RO/DI soaking for a month Phosphates are measuring about 0.10-0.13ppm each week (Hanna ULR).

Tile saw will work perfect. Water cooled carbide blade.

Put away the chisel and hammer. Hacksaw, Dremel with masonry bit, and a drill or screwgun with masonry bit are all you need. A chisel is unnecessary with those three, and is more prone to accidentally breaking a piece you wanted intact.

Diamond blade from Harbor Freight on a 4-1/2"" angle grinder cuts it like warm butter.

I cut the bottom of my dry rock. I use a Sawzall with a masonry blade. It works well

Marco Rock was the first to offer cut shelf rocks I believe.

He had some good advice in a thread here or over on RC a while back.

Angle grinder with a 4 1/2 or 5'' blade is the cheapest option. Just do this outside lol

That’s what i was hoping some one would say. I have one with a 5inch dimond blade for cutting tile.
