Right-angle brace gives you a corner on clamping tasks

Anytime you need to hold two large workpieces at a right angle, say while you're screwing or gluing them together, you need one or more of these plywood triangles. As shown in the photo right, these right-angle braces have two notches for accepting clamp jaws. The circular cutout comes in handy for temporarily holding the brace in place with a spring clamp while you position bar clamps on the notches. It also gives you a way to hang the jig on a peg when you're through.

The more you use this shop helper the more jobs you'll find for it. Although we designed the brace for carcase assembly, we also found it handy for holding an on-edge picture frame rigidly to a bench as we sanded the frame's edges.

What thickness of plywood should you use?

My version a few years ago was to glue up two layers of 3/4" plywood rectangles about 6" x 8", and cut the edges nicely square on the table saw after dry. Then I jugsawed the middle out with 1 1/4" sides. This allows plenty of clamp space. (Perpendicularity of the inside hole was not as critical as the outside.) Glenn Willis

I've made several of these, and use them all the time, especially for assembling cabinet carcases. They definitely come in handy, and they're easier to clamp in place than a framing square is.

I just use a metal framing square. Dave

Have made several over the years that work on the same principle using a 2X or 1X w/a 45 degree brace on each side, leaving enough room at the ends for a clamp of course. Some what bulkier but provides better foot print & stability on large projects, can get right in to the corners also. Have made a few similar to this for small stuff in the past.

Take the time to construct a couple, maybe a couple of slightly shorter ones. And you too will find, as I have, when you reach for the need of them. You will be glad you did.

This appears to be a very useful jig for building larger unit such as the one i am now working on Paul

This jig is very helpful during glue up, as well as while glue is setting up.
