Easy way to clamp at 90°

[DJ Nada]

I saw this in a woodworking magazine, and immediately thought of using this in my next speaker build.

Simpson Strong-Tie concrete form angles are very precise, cheap, and easy to clamp. I'll just put a picture here, and you can imagine the many uses:

I have some aluminum squaring brackets that were made for wood working, but I paid considerably more.
I certainly would have tried these had I known they existed. Funny that they are billed as concrete former supports, but the majority of reviewers mention using them for wood working projects!

[LelandCrooks]

Whoa, thanks for that. I damn near paid like $30 for the same thing in aluminum at woodcraft the other day.

I built mine from scrap plywood.....didn't cost anything.

Regardless of material....you can't beat 'em for getting panels square.

[LelandCrooks]

Me too Bruce. But they get out of square with use. Dropped, thrown, gooped up with PL.

[Bruce Weldy]

Dropped, thrown, gooped up with PL.

Yeah, I imagine the amount of work yours get - they might need replacing once in a while. Mine are still fine.

And it's funny....I just built 'em on a whim because I remembered seeing them in a woodworking magazine years ago. I couldn't imagine trying to build any kind of box, much less a speaker, without 'em.

Empire roofing squares from Home Depot or other similar outlets have gaps in them that allow for small clamps. I used them on my last OT12 build and got some very fine boxes. Relatively cheap and handy to have anyway.

I also picked up some 90 degree clamps from harbor freight. They allow for clamping T joints, corner joints, cross joints and of varying thicknesses. Havent used them yet but hoping they'll work well for keeping panels square.

I've been eye ballin those for a while but afraid to pull the trigger. Let us know how they work out.

I just picked up 2 of the 10x12 and 2 of the smaller ones from home depot. Thanks for the tip!
