material

I made this material by breaking up cotton balls very finely and coating them with graphite powder, then mixing that up with 2 part epoxy and forming it. It is really impressively hard and strong. Beating on it with a hammer on the driveway doesn't leave any visible marks (and makes such a loud noise I might make a video), and cutting into it with a knife only makes a slight mark in the outermost surface probably just into the epoxy coating...

**After polishing the outer surface flat with Aluminum Oxide Sand paper, after the surface was flattened it smoothed the sand paper instead of further smoothing the material

 I found I was able to drill holes through it without compromising the strength of the bulk structure or it breaking into pieces around the hole...
