How do you cut and shape base rock / LR

[snakeblitz33]

Hello all,

I've always taken a hammer and chisel to most of the lighter weight rocks to make certain shapes, but what about ya'll?

I want to make a few flat pieces and some different shapes and what-nots. What kind of blade, saw, or device would you use?

Would it be possible to cut something like that on a tile saw or a large hand held grinder?

Just trying to think of a few ideas of how to get some rock shapes.

An angle grinder works well on soft stone. No need for fancy blades.

I agree with Corey on the angle grinder, but I prefer a diamond cutting wheel on the angle grinder cuts like a hot knife in butter......

How do they cut those large 15"x18" flat pieces? I know it's probably not with an angle grinder!

My guess would be a contractor sized brick or masonry saw. You could do it with a grinder just have to do a lot more cutting on large pieces.

Hmm, yeah, I guess you could do it with the angle grinder, but it would definitely be a lot more cutting. I've always enjoyed rock shapes that are relatively flat, to make plenty of room on top for corals, and to make it look like dead tabling acroporas...

More than likely their using some type of tile saw or band saw.

Yep a good size band saw would probably work too.

or if you got lotsa time make the rock outta concrete and mold it to any shape you want.
