This is a very simple machine to build and to use. You can make a tenon in a minute. There is an adjustable stop block for creating multiple tenons exactly the same size. There is a rail in the back that guides the router to make the shoulder of the tenon. Just clamp it, cut it, flip it, repeat 3 times – you’re done!

This size jig will handle boards 6 inches wide but you could build a larger one if you needed it.

The cut is pretty clean with a plain bit on this oak, just using my fingernail to remove the feathers. You might get perfect results with a down spiral bit. Also, for best results, clamp the work to the left side of the jig, and run your router from right to left.

In the second photo you can see how I use 3 clamps to secure the work, pressing the work against the stop. Make sure you get that stop square – I use a squared block of wood pressed against the hardboard to align the stop.

The third photo shows the stop. The fourth photo shows the jig upside down to show the clamping situation. The fifth photo shows the homemade knob for the adjustable stop.

The last photo shows the results !!!

The tenon jig has a hardboard top that is 10×12. The 2 rails below it are pine 1×3’s and 14 inches long. The hole in the hardboard can be any size, I just made it large enough for the largest tenon I would think of doing.

What kind of router bit are you using? Template? Flush? Forgive me if the answer is obvious.

I am using a 1/4 inch straight router bit. The fence keeps the shoulder straight, so that is the only guide you need. The rest of the tenon face you just take out guiding the router by hand.

OK, I missed the fence. Love the simplicity of it.

Yes it is simple and it works great. The hardboard supports the router as you are doing the cutting, so that helps too.

This is dam clever!
I love the idea and it makes square tenons possible.
Good thinking ‘into the box’.
Best thoughts,
