Wall-Mounted Clamp Rack
Strong, compact storage for pipe clamps and bar clamps
Designers: Paul Anthony and Joe Hurst-Wajszczuk
Overall dimensions: 34"w × 10 9⁄16"d × 10"h
Pipe clamps and bar clamps can be a real pain to store in a shop. They’re heavy, unwieldy, and space-hungry, especially if hung single file on a wall. Of all the clamp racks I’ve encountered over the past few decades, this one brightly outshines the rest, allowing you to stack clamps a half dozen or so deep, saving serious wall space. The rack is both strong and simple to make, consisting of gusset-shaped brackets glued and screwed to a backboard that’s either mounted on French cleats, as shown here, or screwed directly to wall studs.
This 34"-long rack handles up to 25 pipe clamps or 30 parallel jaw clamps. If you need more storage, simply extend the length of the rack.
Note in Figure 1 that the spacing between the bracket pairs shown in the drawing accommodates standard 3⁄4" pipe clamps and parallel jaw clamps with a 1 1⁄8"-wide bar. If your clamps differ, measure the outside pipe diameter or bar width, and add 1⁄8" to that to determine the spacing between the pair of brackets.
Make the rack
1 Rip enough 10"-wide strips from 3⁄4"-thick hardwood plywood to yield the parts you need. If you’re making the 34"-long rack shown, two 8-foot long strips will do the job. Then crosscut the backboard (A) to length.
2 Referring to Figure 2, make a bracket template from stiff cardboard or 1⁄4" hardboard.
3 Trace a bracket (B) onto your plywood and cut it out. If your mitersaw can’t make the 14"-long angled cut, you can use a triangular carpenter’s square and a portable circular saw outfitted with a plywood cutting blade (Photo A). Set the square’s lipped edge against the plywood, and guide the foot of the saw against the angled edge. Saw the rest of the brackets in the same manner.
4 Make the Dado Layout and Routing Jig as shown in Figure 3 on the next page, building it around your rack parts for accuracy. First, saw the jig’s three fences and two rails to the sizes shown. Place the rails against opposite edges of your backboard, and nail or screw one of the fences to them, squarely spanning the backboard. Locate and attach the two remaining fences, using scraps of 3⁄4"-thick plywood (or brackets) in between as spacers.
5 Lay out the dadoes on the backboard. If you plan to screw the rack directly to the wall, first mark out any wall stud locations to work around. Use the dado spacing in Figure 1 as a guide, but adjust it if necessary to suit your particular clamps.
6 Chuck a 1⁄2"-diameter mortising bit with a top-mounted bearing into a handheld router, adjusting the bit depth to make a 3⁄16"-deep cut. Clamp the jig to the backboard (A) and rout the dadoes (Photo B).
7 Dry-clamp each bracket (B) in turn in its dado, and drill countersunk pilot holes for three #8 screws where shown in Figure 1. If your screws are threaded within 1⁄2" of the head, drill clearance holes through the backboard to allow the parts to pull together completely.
8 Fasten the brackets into their dadoes using glue and #8 × 2" screws. Allow the glue to cure fully.
Mount the rack
Note: The rack can be screwed directly to the wall, but using beveled (French) cleats eases the initial mounting and possible relocation later in an evolving shop. If you forgo the cleats, make sure to terminate the backboard ends over wall studs to prevent the ends from pulling away from the wall under clamp weight.
1 Cut the cleats (C, D) and the spacer (E) to the sizes listed in the Cut List, and then bevel one edge of each cleat. Attach the upper cleat and the spacer to the backboard using screws and glue.
2 Locate your wall studs, and attach the lower cleat (D) to all available studs using 3" screws. (It’s best to fasten this particular 34"-long unit to three studs.) Also attach the spacer.
3 Hang the rack on the cleat. Properly installed, it should easily support the load, but for added insurance, drive 3" screws through the backboard (A) and spacer (E) and into the studs.
