Plunge Router Mortising Jig
This simple, shop-made jig transforms your plunge router into a precision mortising machine and guarantees fast, easy, and accurate mortises.
For rock-solid joinery on your woodworking projects, a mortise and tenon joint is hard to beat. Unfortunately, using the traditional means of a chisel and mallet to make the joint can be a demanding operation that eats up a lot of shop time but not with this jig. Featuring infinite adjustability, dead-on accuracy, and smooth operation, this shop-made jig may be the LAST mortising machine you'll ever need to build. And the best part is it can be constructed mainly from scrap plywood.

Some scrap wood and a few simple steps are all it takes to build this basic, must-have shop tool.
Imperial Plans
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.
Metric Plans
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.
Premium Plans
All of the information that you need to build our plans can be found in the standard plan. However, if you want even more granular detail to make your job easier, you should consider our premium plans. These come with additional shop diagrams that we drew when creating the prototypes. Shop drawings are not available for every plan.
