This time I want to show you a quick way of making mortise and tenon joints. I am going to make the mortise in my 3D Router using this 8mm solid carbide spiral bit with chipbreaker. The same one I told you about in a previous video.


Adjust the height of the 3D Router.

Block the “X” axis since we are not going to use it.

Place the workpiece and hold it to the fence using clamps and block it.


Adjust the desired stroke in the “Y” axis.


As the maple wood is so hard, we’ll get the work done in several passes.


I like to use this kind of CNC drill bits for tenons because of these tiny grooves that make the glue more effective.


I made the tenon with the disk and my tenon jig. You’ll need to do it in several passes too. You better hold the piece to prevent it from moving without ever losing sight of the disk. Turn the workpiece and repeat the process.


Now you can cut away the remainder using the sled.

Round the corners using a rasp.


Finally we can assembly, plane and sand the remaining part of the tenon.

And this is the final result!
