Making a Cheap Angle Vise Usable
Cheap (and even nice vises) will come with rough edges that make them not as flexible of a tool as they coul be. By squaring the sides, I can hold this vise in another, or at least have a reference side for quicker set up.

This isn't the most accurate way of checking the tools scale, but It does tell me that it is off by at least a degree. A good thing to know.
