I need some help with a dremel question. I've been wanting a dremel forever to make my "Men Behind
the Masks" customs. I need to hollow out helmets and I'm new to using one. Can anyone help me with what accessories/bits to use for hollowing helmets? I've heard that they can cause the plastic to melt if you're not careful. Has anyone ever hollowed out a Chewbacca head to make a Peter Mayhew custom? Any help would be great!
