This idea came to me yesterday as I was thinking of a way to clamp up a large table with my stash of real pipe clamps still 3000 miles away in VT. It's a combination of a design I saw for a Japanese clamp composed of rope and wedges and a Lee Valley caul-clamp that was released a few years ago. I'm not sure how the pounds of pressure from a wedge will compare to an acme threaded pipe clamp, but I think a simple "snap-the-glue-up-over-my-knee" test will suffice to test if the clamping pressure is sufficient to produce a joint that is stronger than the wood surrounding it. If British rubbed joints can hold, so should this.
More pics to come soon after the clamp is assembled.
