Tenon

All it takes is one router table setup

one for the tenons — which can be time-consuming. To streamline the process, I rout an identical mortise in each mating piece. The parts are then joined with a "floating" tenon. This means you only have one setup for making the mortises.

ROUTING MORTISES

With an idea of how the joint works, you're ready to get set up and start routing. All you'll need is a regular

When I'm building large frame and panel assemblies or doors, I turn to traditional mortise and tenon joinery for long-lasting strength. But for smaller work, I like to use a modified mortise and tenon joint. Most of the work is done at the router table. And, best of all, this joint provides a lot of strength and is quick to make.

In a traditional mortise and tenon joint, you need one setup to make the mortises and a different

straight bit. And for 3/4"-thick stock, a V4"-dia. bit is just the right size.
