I think I will experiment with a pneumatic carving tool a bit and see how well it will cut with a rotary bit. It should give me a better idea before I jeopardize a bit on the CW. I have some cut off scraps that I can't do anything with anyway. If it carves easily and for long enough, then maybe I will try a small sheet on the CW. I will let you know how much damage I do....lol.
