This lamp mounting accessory to the Lathe Track Rack System is used to mount one of three lamps we carry: the Super Nova, the Beacon, and the Aurora. It's tapped with an M8 x 1 thread so the lamps will screw right in. If you own one of these magnetic lamps now—you would simply need to unscrew the lamp from the magnet and put the bracket on it. Be careful not to pinch or cut the electric cord coming out of the base when tightening or loosening the mount. The Lamp Bracket comes with bolts and two star knobs for sliding onto the Track Rack and is about 6 inches long. You can also drill and tap, or simply drill other holes as needed for other special applications you may have.
