I know it's a little late now, but a couple of suggestions that might make life easier.
1 .If you use a bolt instead of carriage bolt,you could use a nutdriver in a drill to speed up the clamping process.
2. if you leave the jaws long on one end and put a scrap of wood the same size as what you are clamping in the other end ,you can slip them on from the side instead threading the clamps over stock and form. Similar to a Jorgensen clamp
You don't need a lot of clamps to put a bend in a piece of wood.Laminating could take a few depending on setup, but some guys bend without any clamps. I use two or three per bend.One to hold it to the form ,and one (quick clamp like the ones pearldrums showed in his caul post) to persuade it into shape.The quick clamp gives a more direct feel for the wood. You can feel the wood give in to the heat . What are you planing on doing with all of these clamps?
