I know I haven't shown any pictures of the woodworking bench build yet but I thought this 90 degree drilling jig I built would be of interest. The block is drilled for a dual purpose. Holes are spaced for the dogs to be drilled in the bench surface and for a support, in the case of long wood pieces, door casings for example, worked in the vise. The problem I had; making perfect holes drilled and spaced with a hand auger bit brace. This was solved beautifully. In order to clamp it to the bench top, where it was not possible to do so in a normal manner, I used a four foot bar clamp parallel to the block then clamped with a Gorjuson clamp at a 90 degree angle. This was then clamped to the wood drill block with a hand clamp. It worked great as you can see in the last photo.
