I'm mostly looking for a way to fab the "consumables" like sanding/polishing wheels and laps, carving burrs, and drills. I have used several different brands of polishing wheels and some I like their "action" but must be ordered from China, and they don't seem to last, While others seem to last, but are too hard for what is called a "soft wheel". I have even tried the "recoated" wheels from a company called Johnson Brothers lapidary, and found them not to my liking. I have been doing a little research into different kinds of polyester and epoxy resins, trying to find just the right "mix" but have not yet been successful.
