I do a lot of intricate boxes and I need the sides to be as perfectly square as possible. I’d seen a video on Fireball squares. They are meant for welding applications, but are also useful for woodworking. I ordered the 8” square. It is cast iron precision ground to near optical quality. It’s amazingly solid and as square as I can measure. Definitely worth a look.
