Recently been watching you tubes on paper wheel sharpening. Looking at prices for "kits," they range from $35 to almost $100. This seems like a lot of money for a couple 8" disks made from MDF. So earlier this week, I set out to make my own from scrap MDF. Made three jigs to make wheels and any more needed in the future. Bought a used 6" bench grinder, replaced the bearings, and reversed the base (switch still faces forward) so wheels turn AWAY from operator. Cut out, and trued wheels (mounted on grinder.) Bought some white, and green rubbing compound to charge finishing wheel, and some carnuba wax for grinding wheel. Ordered some 220 grit silicon carbide off Ebay for making grinding wheel. To make grinding wheel, you take wood glue and spread it around outer surface of MDF wheel, then coat with SC grit. After glue has dried, rub carnuba wax on surface of wheel. To charge polishing wheel, turn on grinder and apply rubbing compound. Results were GREAT!. Sharpened a couple of kitchen knives in less than a minute each. They are so sharp, hair literally jumps off my arm to avoid being cut off. Izzy Swan has a video showing how to charge wheels along with usage of system. Anybody else using this system?
