New life for spring clamps
Frequent use of spring clamps wears out their cushion tips. At that point, I replace them with 11⁄2 " lengths of old garden hose. For 6" clamps, 5⁄8 "-inner-diameter hose fits perfect. To get the hose piece into place, warm it with a heat gun, open it with needle-nose pliers, and slide it onto the clamp. Then, heat the hose piece again and press the clamp to a board to slightly flatten its tips.
