I’m not terribly experienced in building boxes and drawers, and I observed something unexpected today. Anybody else notice this?
I was gluing up drawer boxes, 1/2” baltic birch, about 8.5”x24”x19” outside dimension. I’m using a lock rabbet corner joint (see picture). On the first 2 of 4 I put the clamps on as shown in the upper picture; no particular reason, just that I would put the clamps on the first side, then spin it around, and put the clamps on the second side the same way. These were not square as they went together, and I was having to use a squaring clamp. They were both out-of-square the same way: the long diagonal was between the moveable jaws.
On the next 2, I was using much longer clamps, and I decided to have all the tails pointing the same way to make them easier to handle (as shown in the lower drawing). When clamped up this way, they were square. I went back to the first 2 and flipped the clamps on one side, and they became square without a squaring clamp.
Am I the last one to know about this, or have I discovered something new?
