I wanted to make a small box for a project and I wanted strong joints. A mitered and glued box wouldn't be strong enough for what i had in mind so I tried box joints.
There are all kinds of commercially available jigs and tools to assist in making box joints (or dovetails) but I made my own jig quickly and easily with the router table at TechShop and some scrap wood.
Router table and a 1/4" straight bit
Compound miter saw or table saw
3-4" wide board
I made it at TechShop
