Hi Tigtorch, I have cut these scales using a Dremel tool with a cut-off wheel. The capacitive cells that the head reads from to derive the position are contained in the strip that is affixed to the front of the scale. I have found drilling holes in them for remounting is best done with a carbide bit. I used a bit that was originally designed for drilling in tile or concrete. I put it on the diamond wheel to clean up the cutting edge, works very well.
