The Disc Smasher from Steck Manufacturing reduces excessive curling and limits disposal and returns of discs. Its reinforced nylon base with an 8-inch-long metal center post can hold up to 25 5-, 7- or 10-inch grinding discs. Disc Smasher’s capture-and-store design forms the disc to conform to the base for any of the three disc sizes, ensuring safe, flat and vibration-free grinding. Existing warped or curled discs can be restored back to proper shape after a week of direct pressure from the Disc Smasher. The base can be wall- or bench-mounted. This kit sells for $55.
