Magnetic Clamp Pads
My C-clamps and steel bar clamps can exert extreme pressure, but the small steel pads also can dent the wood, especially softwoods like pine. So I made these wooden pads that attach to the clamps’ steel pads. I started with 1⁄2-in.-thick, 2-in.-square blocks. I drilled a 3⁄8-in. recess in the center of each block and used epoxy to glue in a 3⁄8-in. round rare-earth magnet. Now I can quickly attach pads to any of my metal clamps.
