IHHHH SHOP PROJECT l-Beam ClampsStoring I-beam clamps is a challenge. They're heavy and awkward to carry. So I built a sturdy hanger that holds the clamps securely, yet still makes it easy to lift them in and out. This hanger consists of two parts: an upper and lower rail, see drawing. To set a clamp in place, just stick the bottom end in a "pocket" in the lower rail. Then slip the I-beam into a slot in the top rail and lock it with a turnbutton, see photo. The rails are identical in length. But because of the large holes in the lower rail, it needed to be a bit wider. Both rails are made by gluing up two pieces of3A1'-thick hardwood. LOWER RAIL. Once the glue dries, you can drill the large holes in the lower rail. I also routed a chamfer around the rim of each hole. This helps me quickly "find" the holes when I'm putting clamps away. UPPER RAIL. Now you can turn your attention to the upper rail. It's rabbeted along the front edge to form a lip for the turnbuttons. The lip acts as a "stop" that prevents the turnbuttons from accidentally pivoting down (out of the locking position). The next step is to cut a series of open slots in the front edge. These slots are sized so the I-beams fit snug when the turnbuttons are closed. TURNBUTTONS. At this point, you can add the turnbuttons. These are pieces of lA" hardboard with a radius sanded on each end. A single screw holds each one in place. MOUNT HANGER All that's left is to screw the rails to the sides of the cart, see details 'a' and V ▲ A spring steel clip securely grips each of these pipe clamps. But a quick tug is all it takes to release the clamp. k To remove one of these heavy I-beam clamps, just flip up a turnbutton. Then flip it down to lock the clamp in the hanger. #& x 2'/z Fh WOODSCREW _Ji SIDE 1%" DIA.

But here, a metal clip grips the clamp and holds it in place, see photo at left. Once again, the bottom ends of die clamps fit in holes drilled in a thick lo wer rail, see drawing. But the pipes aren't as big around as the I-beam clamps, so I drilled smaller holes. As before, the lower rail is just screwed to the base of the cart, see detail V Since my pipe clamps are different lengths, I made two upper rails. To hold 24"-long clamps, I mounted one rail about halfway up the sides of the cart, see detail 'a.' The other is closer to the top to hold my 48" clamps. Now it's just a matter of adding the metal clips. I used ordinary broom clips made of spring steel. (These are available at most hardware stores.) CHAMFERS VA" DIA.
