Just built this miter key jig tonight, I havent used this yet but I hope it works…haha. Got ahold of some veneered MDF that was headed for the dumpster I hated to use it for this but I wanted it to be straight and sturdy so I went with it. I have seen many different styles of these and although I have never used one I decided on this because I have access to two different table saws (dont have one of my own yet) so I couldn’t make one that rides in the “miter grooves” on the table saws cause they are different. This one just rides against the fence, as you can see in the first pic the piece that is to the right runs the fence, so I can use it with any saw. Comments?

Harley its a miter key jig for boxes. It runs the way you see it in the first pic, just run the piece that is staight up and down against the fence and you raise your blade to cut through the jig and into the box (not too high). As you run it through once it goes through the box you pull it back as you dont want to cut your jig apart. Also you can use stop blocks in the jig to move the box farther to the left so you dont have several cut lines in the jig. Here is a link to show you exactly what it does (this box was made by mjasper) you can see the “keys” on the corners of the box, it is decrative but also makes the joint stronger. I hope i explained it well enough maybe someone else can do better because I am also new to woodworking and am in the process of making my first box

Have your say...
