I’m in the early stages of a dining table build, but I already know I’m going to need some clamping cauls for the 40” wide table top. I had some time while waiting for glue to dry, so I decided to make some cambered cauls.
The concept here is that the shallow arc in the cauls, when compressed by clamping pressure at each end, will apply even pressure along the length of the caul. If I were to use flat faced cauls, they have a tendency to bow up in the middle when the ends are clamped. In order to keep all the boards in a table top glue-up flush to one another, even pressure along the cauls is important.
I only really needed 48” long cauls, maybe 3 pairs, but when I started looking at prices, it started to make sense to make more.
A certain company that sells these would have charged me:
$358 for (4) Pairs of 48”
$278 for (4) Pairs of 36”
$190 for (4) Pairs of 24”
= $826 total
Instead, I spent $150 for the lumber and $47 for a Whiteside T-Slot router bit.
= $197 total + 2 or 3 afternoons
More than I intended on spending, but these will come in quite handy during table top glue-ups of any size.
