Quick set tenon jig

So I’m about to dive into a coffee table project for my brother. He just bought his first house and could use a home warming gift. The thing is, I’ve made mortise the normal way (miter gauge and dado stack), but I was dying for more accuracy and repeatability. My (small) table saw is finnicky with heigh adjustment, there is a bit of backlash in the adjustment screw and it made it hard to get accurate tenons. Plus, with stock of various width, I kept having to readjust my blade.

No more ! I bought these quick set tenon jig plans from Matthias Wandel (I have bought and built the 16” bandsaw as well, but this project is for another day) at woodgears.ca and let me say this thing is fabulous. I’m a mechanical engineer by trade and I like accuracy and being able to work with machines that give accurate readouts. This jig does one thing, but it does it well and quickly.

Basically, you use the dial indicator as a measure of the displacement of the jig/piece of wood, which allows accuracy to the thousandths of an inch for the width of the shoulders and the width of the tenon. You use the lever upfront to move the carriage that holds the piece of wood and setup stops for each cut. I’ve used the jig to make a few test cuts so far and usually end up within 0.001-0.003” of the target value, so I am very pleased. It has a movement range of about 2 1/2”, so it should be plenty for any regular sized stock.

I’ve painted the plywood parts and the rest of the jig is made with scraps of cherry, finished with water based polyurethane and wax on the moving parts.

Now that is one fine device you’ve created. Looks like one might need an engineering degree to use it. (-:

I think I need to put that on my shop jigs to build list. Thanks for sharing.

Julien, that is a mighty fine build. I too have built Matthias bandsaw and several other of his inventions. I have had my eye on this build for some time now. You have given me a nudge now to do it. Thanks for sharing!!

Nice work. Matthias is a gift to this forum! He has a fantastic gear design software program that I use for my clock making and it has saved me countless hours of calculations. I’m sure you’ll get lots of great usage from that jig. Incidentally, I plan on purchasing those plans soon and build one of these myself. I’m all but done using my 1000 pound delta tenon jig!!!!!

That looks like a terrific idea to put on the list of need to make jigs. Thanks for posting and thanks for the link to Woodgears.

I encourage anyone who has the plan to go ahead and build it. It takes a minimum amount of material and can be done in about 3 days (I milled all my stock to size on a sunday morning, then did everything else over the following weekend).

@Jeff82780 I strongly suggest self aligning bushings. The ones I got were marketed as “vibration damping”, but they’re basically regular bushings held in a rubber sleeve. Even then, aligning everything was a bit fiddly; the play in the bushings really helped.

Nice work. I’ve been debating buying the plans, you may have sold me.

seems very intricate, but if you are getting the results you want then that’s definitely a winner :)

I have no idea what the hell is going on here, but that’s a pretty rad rocketship or whatever.

(Your tenoning jig has way more moving parts than mine; I bet it actually works great.)
