I am wondering if anyone has sandblasted lettering onto either polished Granite or other stone using a rubber mask on the stone.

My question is limited to... will I make decent although slow progress w a true 5 hp comp, typical 100 lb pressure pot, and Black diamond abrasive?

Like doing a very small simple Tombstone.

I know all bout my limited CFM..

I have done a few vehicle frames, BBQ pits, no problem...

My question is about will my equip cut decently into polished Granite w some 3D affect more than Etching.

I know Granite is harder than many other stones.

Do I HAVE to move up to more expensive like AL Oxide or similar ?

Or will the cheap available Black Beauty slag stuff work?

I want to get like somewhat 3D, not just "Etched"

Can I do it w the equipment I have listed if it is a hobby w more time than money .....not production ?

Obviously, I wish I had a huge trailer comp driven high cfm and appropriate pot, but I don't.

Thank you all, Marc
