I tried on canvas micarta a while ago but it was difficult. Not even as soft as the hardest wood. Then I broke out the dremmel tool, and tried with a few different bits. After the toxic dust plume settled down, I bailed on it. I would recommend either using a sample piece of G10 or like I did, which was to try it out on the inside of the scales. Definitely wear a dust mask. Post some pics if it works out for you.
