We're always looking for ways to keep our tools and shop more organized. A couple of months ago, we designed this holder for our grinders. They screw into any surface, and fit into slotted tool chest doors. The shape was cut on the plasma table and then shaped on the press brake. They hold standard grinders up to 4.5". Once our friends found out about these, they started asking us to make them for their shops and garages. We sell a set of 5 for $65 - check them out on ebay.
