1 Cutting the stock for the jig
The large collection of clamps in most shops—and their awkward size and shape—can stretch even the most organized space to the limit. The mobile clamp rack shown at left can be stored against the wall, then rolled to any part of the shop where clamps are needed. Start by cutting the pieces to size, referring to the illustration for suggested dimensions. The six rails (top, median, and bottom) the two stiles, and three crosspieces are all sawn from 2-by-4 stock. Cut the four skirt pieces from a 2-by-4 and the base from VLinch plywood (inset).
Prepare the rails for the joinery by cutting end rabbets that will fit into notches and dadoes in the stiles. The rabbets should be IV2 inches wide and 3A inch deep, except for the top rails, which require a rabbet only 1 inch wide. Notch the top end of each stile on three sides, then rout back-to-back dadoes near the bottom end and middle of the stiles; make the dadoes ЗУ2 inches wide and ЪЛ inch deep. Also cut a notch ЗУ2 inches wide and % inch deep from the bottom of each stile. When you assemble the rails and stiles, align the two halves of each rail face-to-face (right) and attach it to the stiles with screws.
3 Mounting the crosspieces to the stiles
To join the crosspieces to the rack, cut a ЗУг-inch-wide dado in the middle of each piece and screw them in place (above). The middle crosspiece will rest on the median rail. The top pieces will rest on the outside shoulders of the notched top of each stile.
