Holding it down — that’s half the battle when it comes to woodworking. (“Knowing” is the other half, right?) Just keep it still. Think of the KREG Universal Bench Klamp as a pair of adjustable locking pliers mounted to the workbench. This idea is that the system allows you to apply an incredible amount of pressure to the joint line.
The heart of the clamp is a 1/4″ x 3″ x 4″ steel plate which can be inlaid in the bench top — or fastened to a piece of plywood and clamped to the bench, though a clamp clamped to plywood clamped to the bench seems a bit redundant. Then again every time we say that in the shop we wind up doing it the very next week.
The clamp, which rotates 360° on the plate, has a 3″ throat depth and can be removed by a sliding screw head to keyhole connection. This might be a bit of a hard sell at $35 a pop though. A few hand clamps and a workmate might work just as well and not leave holes in your bench — well, at least not any more holes then normal, that is.
