Tricks of the Trade
EDITED BY PAUL ANTHONY
Vise-clamping Odd Shapes
n my work, I often need to secure odd-shaped pieces in my standard bench vise. To do the job, I devised a pair of auxiliary cauls that attach via rods to thick wooden pads on my vise jaws. One of the auxiliary jaws is fixed, while the other one can swivel to accommodate pieces with non-parallel sides.
To outfit your vise, begin by makinga 1"-thick hardwood facing block for each jaw. Using the drill press, bore three equidistant l/2"-diameter holes through the width of each block to accept the rods. (Drilling the holes completely through prevents clogging from chips.) Then attach the blocks to your vise jaws with screws or bolts, aligning the top of each block with your workbench surface.
Make the cauls from stout hardwood that will resist flex in use. Mine are 18" long, 2V2" wide and 1" thick; make yours from any size that suits your work. Next, use dowel centers to transfer the ^"-diameter rod-hole locations to the underside of the cauls. The swiveling caul reeds only one hole in the center, while the mating caul is drilled to match only the two outer holes. Bore these holes at least V4" deep, again using the drill press. (This hole con figurat ion al lows interchanging t he ft xed and swiveling cauls on either vise jaw.) Glue 1/2"-diameter steel rodsor wooden dowels into the cauls, leaving about 2" projecting to fit in the wooden blocks. Face the bearing surface of
each caul with rubber or cork to aid gripping, and ease sharp edges with sandpaper.
To hold curved and odd-shaped pieces, attach a suitably shaped piece to one or both of the cauls. For panels and other wide work,
the innermost caul can be mounted in holes drilled in the workbench top instead of the holes in the inner vise jaw.
