what’s your guys favorite jig (bought or hand made) for squaring up boxes while glueing or screwing together? Been doing a lot of plywood boxes and looking at different techniques, whats yours?

Any difference between clamping the 90 on the outside or the inside or both sides?

Made out of some scrap wood and a few screws. Work great and easy to use.

Thanks to Izzy Swan. Video on making and using them here:

Great video, thanks Izzy & Brad.will have to make a few . I looked for plastic one on Amazon,the problem is,you can’t buy just one,you need at least 4 .with the shop made type we can have as many as we want,different sizes too for smaller trinket boxes or similar projects. Great quick project.

I just make sure my parts are cut square especially the back of the bottom of the box. I hardly ever use squaring blocks.

So you don’t use clamps when gluing?

A little exotic: I have a vacuum pump for veneering
and I made a right-angle fixture with vacuum seals
on both faces. Sometimes, when making a bookshelf
case or something like that I use it to hold parts
together while putting nails or screws in. An advantage
is one side can be sticking straight up so it helps
with quick assemblies when I don’t want to mess with
setting up an assembly table.

I don’t use clamps for squaring purposes. Since most of my work is cabinet type work I use screw and applied ends don’t need clamps.

I read in ww’ing magazine (not sure which one) in the reader tips section, that a 2 gang (four square) metal
electrical box works well for the inside corner to clamp to. The writer claimed the boxes were dead square. I have not yet had the opportunity to try this, so I can not verify. Seems like it would work though, and boxes are cheap, rigid, and durable.

Cabinets: I use Rockler jigs (one of them is NOT square, BTW) but really only to hole the pieces while I screw them together.

Drawers, boxes, carcases, etc: They usually have a bottom, right? Install during glue up and & check diagonals.

I’ve found if the parts are square & joints are tight, the assembly will be square, too.

I made a couple of these about a year ago but mine are 16” on a side. I use them on large stuff.

And I “accidentally” got a couple of these that are 6” on a side in a box I bought at an estate auction a while back. They come in handy for smaller stuff.

Same here. I also made a set of smaller ones. Pretty handy and used up some scrap 3/4” ply.

Yep Me too, they work great, I cut the hole larger for mine to be able to use my quick clamps
