Thompson Brace Gluing Cauls

About This Item

Don't crunch delicate braces when gluing
Gluing a loose brace means clamping, and many clamps don't fit well on delicate curved braces. The clamp slips off or leaves a crunch mark on the brace.

T.J. Thompson's glue-resistant nylon cauls fix this problem. They fit over the brace, protecting it from the clamp and evenly spreading the pressure. Inside, the cauls are shaped with an arch to match scalloped guitar braces.

Set of two brace cauls: narrow and wide to fit any brace you're gluing. In most cases, they fit snugly enough to stay in place while you bring in your soundhole clamp.

Great for working on most Brand name guitars


Verified Buyer

I make my own braces for vintage pieces and these work just ok as they don't "grab hold" bc of the shallow depth in the middle of the piece. I'd like to see an alternative where the depth is uniform all the way accross.

Great for scalloped braces. Makes the challenging, but common loose X brace at the bridge plate repair a whole lot more rewarding.
