Step 1: Background
I got this idea from my dad a LONG time ago. Where he got it from is anybody's guess but the idea has been kicking around for a while.
He originally made his Turn-Me-Over Stone using a felt pen but since I have a laser cutter I've used that to engrave the text onto the stone.
Step 2: Selecting Your Stone
If you're going to laser-engrave your stone you'll want to select a stone that's relatively flat because a laser-engraver has a focal plane that needs to be observed.
The next consideration is the smoother and more polished the stone, the better it tends to turn out.
Mechanically tumbled and polished stones work great. Flat sliced & polished are the best.
You'll also want to pick a rock or stone that is dark in color because the text engraving tends to come out lighter than the un-engraved surface of the rock.
Amethyst works great, but you most likely need to buy this mineral from a gem shop because it's not something commonly found everywhere.
Step 3: Laser Engraving Your Stone
Set the focus on your laser cutter appropriately. If you have more than one lens with your laser cutter, choose the longest one because it will have a larger depth of field to handle any variations in the flatness of the stone.
Power & speed settings will depend on the type of rock that you're engraving. I've found that you can over-do things so if you can test your settings on an identical type of rock before you laser the one you actually want, that's the best thing to do.
Also, you can always run the laser several times and get a better engraving if you don't move the rock.
A piece of window putty, or Plasticine can be used as a base to hold the stone in place, and keep it level.
