Marco rocks

[phi delt reefer]

you looking to make a "flat side" or just cut down the size?

water saw used in tiling would work but you need a big sucker with a large enough blade for big pieces. Probably not worth renting.

i just got some marco and it doesn't seem to be that hard, i offer the cheap and simple solution of hacksaw!

I just go all lou ferrigno and wail on it with a hammer , you could probably use a chisel too but i find it less fun.
