I'm gonna need 48" long clamping cauls for when I get to gluing together Jason's 40" wide table tops, so I'm gonna make my own cambered clamping cauls similar to Bowclamp.
|Bowclamp Clamping Cauls|
This will allow me to keep the boards of the table top flush to one another during glue up. These cauls apply even pressure across the entire width of the table top using one f-clamp at each end. The clamps pull the camber flat, and the camber applies even pressure along its gentle curve. You wouldn't otherwise be able to get any clamping pressure in the middle like that.
