Making shop squares
When I last made a try square, I made it from two pieces of solid wood with a fancy box joint joining them, but, when the glue dried, it went marginally out of square and I had to trim it slightly. This time, I figured I'd just cut it from Baltic birch plywood.
I also glued on a wider part to the base of it, also made of exotic hardwood. This will allow the square to be placed against the edge of a piece of wood, and not flip down if you let go of it. It also allows the square to stand on end on its own.
Though I was careful, when I checked it against a trusted framing square, I found the inside long part was out of square by about 0.2 mm along it's length, so I trimmed it on the table saw to fix that.
I was worried the exotic hardwood trim might start to crack off if the square was dropped too many times. So I cut a slot in the end and glued in a spline to tie the trim to the main body of the square.
Clamping squaresA few years ago I made some clamping squares (you can see one of the old ones on the table saw in this shot). These are used like corner clamps, basically, clamped to a corner of something to make sure it's square while it's clamped and the glue dries (examples here and here).
These are super handy, so I wanted another set for my new basement workshop.
My old squares were made out of solid maple with a very layered box joint at the corner. The joint is the weakest part of the square because I had to cut away half the wood from each piece for the joint, so I figured, why not just make the whole square out of Baltic birch plywood. The straight parts really don't need to be any stronger than the corner.
I didn't have plywood thick enough, so I glued together some 18 mm plywood and some 9 mm plywood, making these 27 mm thick.
Then made some tool holders for them in my basement workshop. Made a video of Setting up and installing the door at right in this photo.
The tool wall is actually one I made for my big garage workshop but moved to the basement after I moved my good tool wall from my old basement shop into the big garage. The workbench was also originally in the big garage workshop as well.
