Most types of clamps suck for gluing up furniture. What you really need is a way of getting even pressure all the way around the object, and the best way to do that is to use a strap clamp like the Pony Rapid acting band. It’s simple: its strap wraps completely around your furniture object — no matter how many corners it has — without marring the finish.
This clamp consists of a 1″ x 15′ nylon band that hooks into a locking mechanism. Just loop the strap over the object, hook it in, and pull. Once everything is good and tight you can lock the strap into place with a few turns of the handle. Then you just have to wait for the glue to dry.
Plastic non-marring 1″ x 1″ jaws allow for a great fit on corners the metal levers provide rapid adjustment and release when you need to reposition the project a bit.
And remember: strap clamps aren’t just for furniture work. Strap clamps are the way to go when gluing up any oddly shaped project. For $18 I might have to shell out for one, too. it looks like it’d work much better than the cargo straps I normally use.
