Build the clamp racks

To make the holder, cut a piece of MDF to length and width (8 3/4" long x 8 1/2" wide, in my case) and cut a bevel that’s 3º from square on the back edge to tilt the front edge of the holder slightly. Then lay out and cut the notches using a dado blade and mitre gauge with a sacrificial fence. On mine, these notches measure 1 1/4" deep (the depth of the bar) x 5/16" wide (the thickness of the bar plus 1/16"). Notches are spaced 1" apart.

Next, make the back plate. Cut another piece of MDF to 6" wide x the length of your holder, then glue a cleat section to it. Rip the top edge to 3º from square on your tablesaw.

Use more glue to join the two pieces together to form the rack. Pay special attention to the bevels! You want to ensure that the bevels match up so you have a nice flat surface at the back. Once glued, reinforce the joint by first predrilling countersunk holes every 2", and then driving #8 x 1 1/2" wood screws into both the backer board and the cleat.

Place the rack into position, drill a 1/4"-diameter hole through the back plate and into the wall cleat, then secure the rack in place with a #8 x 1 1/4" wood screw. Gather all the clamps you have scattered all over the shop, and put them in place in your rack.
