PVC Pipe Clamp Rack
To make the rack, cut 2-in. lengths of PVC, and with a hacksaw or band saw, slice them lengthwise about 3/16 in. past the diameter's center line. This creates the gripping action to firmly hold the heavy iron pipe. Drill and countersink two holes in each PVC piece, then space and screw them along a pair of 2-in.-wide boards. Attach the upper board to your shop wall and snap a pipe clamp in either end to position the lower board for screwing to the wall. Plus: 28 secret clamping tricks from woodworkers.
