Every once in a while, you run across a project that calls for a clamp longer than any in your shop. You figure it's time to go buy longer pieces of pipe.

Instead of running to the plumbing shop, clamp short pieces of scrapwood across the overlong part as shown above. Then, clamp the joint with one jaw pulling against the scrapwood and the other against the opposite side of the joint.
