In his post bent wood jig Russell is likely attacking the same problem I believe. http://lumberjocks.com/topics/41718. I have seen this or similar here and there but Russell’s was the last, lol.
Basically it’s a shaped clamping cull. Additionally you could look to shipwrights use of wedges. Some plywood, trued 2x’s, and some hardwood for wedges would likely make a more than acceptable clamping jigs for low cost if you are doing this repeatedly. The time investment to cut and the build jigs against the high number of quality clamps is something you would have to weigh for your individual needs.
