Part 3 – Carving the Stones
Carving the element symbols onto the stones proved to be much more time consuming than I had anticipated. I saved this step until after the electronics were complete for fear of damaging the patterns. After a some experimentation on some scrap foam I found that the best way to create the marking was by using the Dremel again with a conical sanding bit. I printed the patterns shown below and temporarily attached them to the sides using a light touch of spray adhesive. This way I was able to carve away the black areas and then peel off the remaining white paper. I had to make a few slight adjustment to the pattern to accommodate the power switch but the pattern changes are nearly imperceptible especially after painting.
