Totally random... thoughts on cauls

[Jacob Reverb]

A trick to ensure that the two cauls put equal tension in place is to clamp . . . never mind. A picture is better. Imagine that their are clamps at either end holding these two boards together over a spacer. Then snap a chalk line, unclamp and cut along the now curved line.

That's slick!

Peter, Larryclamp seems interesting, but wouldnt a glue joint be just about as accurate?

What determines the size of the spacer used between the boards?

Thanks,

When I did it last, I used a 4x4 on end about 8" tall. When I screwed down the clamps, I just tightened until the tension felt about right. The 2x4s I was bending lost about 3/4 of an inch at each end.
