Need some suggestions

[mfatty500]

I have a friend of a friend that would like to cut out a name from a boulder that has his dad's named engraved into it, he would like to have just the name cut into a monument type of stone for a keepsake, as the man is dead. I told him to contact a monument co. Maybe they have a process to do so. Maybe a very large diamond blade (chainsaw) or water jet?

Check with monument companies that make headstones, there are still some that cut their own down from large blanks. Granite quarries have equipment to cut some pretty large stuff, so if you have any around you, check with them too.
You'll probably have to transport it to them if you find one.

Cut a stencil from "sandblast" vinyl (think it's called resist), apply it then sandblast.

The name is already on it, the OP wants to completely cut the boulder apart around it to just keep that part.

Hmmm, you need a stone cutter or some place that would have one. As mentioned, check into a headstone business or maybe a landscaping/paver business.

Cut a rectangle, place over the name, blast the rest of the boulder to oblivion? Bring a 12 pack.

If this works, I'd like to know the brand of the masking material.

There was this stuff, If I recall correctly, they made a documentary about it in the late 90's. Surprised it never really took off...

turn the boulder & cut with a concrete saw (“filet” the stone)

use the kind of saw they use when repairing waterlines under a road.

i would call united rentals if i were doing it in NJ. I have seen these saws 18”, 24” & 48”. 48” will cut 20” into a stone. Rotate the stone to complete the process.

find a smaller rock and blast the name into it, roll the original boulder over so the name is covered up.

Engraving boulders and working with stone is what I do. I'd suggest using feathers and wedges to split the stone until the section is small enough to slice with a diamond blade.

Every stone behaves differently, so go carefully.
