If you have a big shop, a rollaround clamp rack is better than any wall-mounted system. It holds every type of clamp in one compact space, and you can wheel it right up to your work area. That saves miles of walking back and forth to the clamp rack.
This version is built from oak legs and 3/4-in. plywood shelves. Note that the front and back edges of the plywood are all the same length but have 7-degree bevels. The shorter pieces of edge trim also have 7-degree angles. When you cut the edge trim to length, it should be measured and cut to the bottom, longest part of each board. Assemble the legs first and then preassemble the shelves. Then screw on the top and bottom shelves. Rest the rack upside down and slide in each shelf. Make sure they’re evenly spaced and screw each one to the legs. Add the wheels, varnish it and you’re done.
