Wonder Dog® clamps? Well, you have to wonder why nobody thought of them before and then wonder if you can get along without them.
At 165mm long, the versatile Wonder Dog clamp can be used anywhere you can drill a 19mm (3/4in) hole. It makes it easy to clamp curved work and irregular shapes. Since the dog head has two screw holes, any shape of tip can be cut with a scroll saw and quickly attached for specialized work, giving good control without marring work.
Using a Wonder Dog in combination with a standard round bench dog, you can make a clamp of any length by drilling 19mm holes in a 2 x 4, 2 x 6, etc. Two pieces of plywood with 2 x 4s between them for spacing can be drilled in a pattern to provide clamping for curved work and an infinite variety of other shapes.
At the lowest projection, only 15.9mm (5/8in) of the dog head is above the bench. The swivel handle lets you apply ample clamping pressure in any position. The dog is drilled and tapped at a 3° angle to ensure that work is held tight to the bench.
The Wonder Pup is the same as the Wonder Dog in all respects, except that the post is shorter (70mm instead of 165mm) and has no side spring. The side spring is replaced with an O-ring for slightly elevated clamping. For use in bench fronts, drill-press jigs, etc.
