Recently, while applying solid wood edging to some plywood shelves for a bookcase, I ran short of the necessary clamps to finish all of the glue-ups. With only spring clamps left in my arsenal, I came up with this clever way to use rubber strips cut from a bicycle inner tube to clamp the edging in place.
STRIPS OF TUBING. I started by cutting the inner tube into strips long enough to wrap around the top edge of the panel. These should also be long enough so the rubber extends below the tips of the jaws on the spring clamps.
CLAMP UP. Place the glued-up solid wood edging on the plywood panel and hold a piece of tubing in place with a spring clamp. To increase tension, simply pull down on the tubing sticking out below the clamp jaws.
