Box Joint Jig
Dial in perfect-fitting box joints on your table saw or router table. This jig’s micro-adjustment system and locking feature make it easy.
The most impressive thing about this box joint jig isn’t the tight-fitting joints you can make with it. After all, that’s what you expect from a precision made jig. What’s really unique is how quickly and easily it can be adjusted. Most box joint jigs require an almost endless amount of tweaking. This jig, on the other hand, can be set up in a matter of minutes. The secret is a built-in system that allows you to adjust both the size and spacing of the pins and slots that make up a box joint in extremely fine increments. By simply turning a knob, you can set the jig to cut slots that range in size from a width of 1/4" to 13/16". A second knob changes the spacing of the pins and slots. This tightens (or loosens) the joint, which allows you to sneak up on a perfect fit. The result is perfect-fitting box joints every time.

The United States Customary System of Units (USCS or USC), more commonly referred to as the English or Imperial system, is the standard set of units for our plans. It uses inches and feet for measurement. This is the one you probably want if you are in the United States, and it is the one we have traditionally offered on this website.
The International System of Units (SI), more commonly referred to as the metric system, is the alternative set of units that we have available for some of our plans. It uses millimeters, centimeters, and meters for measurement. This is the one you probably want if you are outside the United States. These plans are provided by our business partner, Australian Woodsmith, and are based on the original Woodsmith plan. However, dimensions and other elements of the plan may vary between the metric and standard versions. Be sure to double-check the plan before building.
