Squares do come in all shapes and sizes, regardless what the name may suggest. This miniature square mimics others sold by big name tool companies, but with the twist that you can make it yourself. They're very useful for checking squareness on small parts, or for using as small repeatable stops when you need to mill or turn several copies of the same item. Since it's so small and handy it's a nice pocket companion for your workshop apron. The project is fun, and will teach you a bit about work holding, checking for square, working with small tolerances and making working parts.

The plans contain dimensioned drawings of all parts, as well as IGES files so you can explore and modify the different parts of the square in your favourite CAD environment.
