    I have made several signs by routing letters into timber, and painting the recessed cut-out a different colour to the timber surface. The letters were about 50 -80mm high, and I used a dome cutter. To get a more accurate letter size and shape I used a PC to print out the text I wanted, in the right sized font, and stuck this to the timber before routing through the paper into the timber.

    I would now like to repeat this, but using a block of sandstone. I haven't tried, but feel fairly sure my (cheap) router cutter isn't designed for sandstone.

    Are stone router cutters available?

    Or do I need something like a mortar raker in an angle grinder? Which I suspect is nowhere near as easy to control as a router.

    Any other ideas?

    Stone masons use diamond impregnated bits that usually run in water cooled machines. Or its done by hand with a chisel.

    If its a one off you may get away with carbide burrs or grinding bits that are usually used in a die grinder. The grit will likely bu*r your router so buy a cheapy to try it out. You will need one with a 6mm collet as thats the standard size for the grinders

    If you only need to do it once I would not bother. I had a job once that needed something similar and I spent ages thinking about it and then talked to a 'monumental mason' (i.e. the chaps who do grave stones). They did it for me. It only took them half an hour and they didn't charge me very much.

    I'm sure that I could not have done it half as well they did and it would have cost a lot more.

    This is a specialist Job, PCD (Polycrystalline Diamond Cutters) cost a lot of money for a one off.

    I would suggest taking Binfield Carpenters advice and asking a Monumental Mason to do the job for you.

    Thanks for the replies, I will go down the route suggested by B.C. as it's a one-off.
