I’m embarrassed to admit it, but I started this project some11 years ago :^o

The design came from Woodworkers Journal, though I modified it by using some 1” Birch plywood left over from another project, and by increasing most the hardware to 3/8”. I drafted the swivel parts from a template in the mag. and cut them on the CNC router at work back in 2003. They’ve been sitting on a shelf in my basement ever since. The white rubbing strips are all UHMW poly, and they slide quite smoothly. The swivel support has a sacrificial facing of 1/4” Masonite.

The cut outs in the triangular jig supports are sized to fit your TS fence. But I sold my Craftsman contractors saw and refurbishing an old Jet cabinet saw with a Biesemeyer fence, so I had to re-cut the notches on the band saw.

The fence is adjustable in three ways. The swivel has a stop screw that is adjusted to the 90 deg position. The support plate has a screw that flexes the rubbing strip to square the main plate to the table, and there is another rubbing strip that rides the back of the fence with an adjustment screw to take the play out.

The jig is very solid and stable. Since some of the 1” ply pieces already had stain on them, I stained the entire
project to match and then finished it off with two coats of rattle can poly.

Because I used 1” ply, I can easily subtract 1” from the scale on the fence to position the cuts.

Thanks for looking.

Looks great Matt. Let the tenoning begin. I have a mortiser, but no tenoning jig. I either need to make one or buy one. Seeing this makes me want to make it. What does the clamp thru the hole do?

-- Bill M. I love my job as a firefighter, but nothing gives me the satisfaction of running my hand over a project that I have built and just finished sanding.

Now that the tendon jig is complete.
Does this mean we can expect to see a project utilizing M&T joinery…..
In another 10+ years???

I find things like this will always get done when the need arises. Nice project although a long process, blame it on waiting for material. LOL Pat

Bill….. the circle hole on left provides a place to sneak in a clamp, so I shot the pic with the clamp to illustrate that. The hole on the right provides a more convenient place to firmly hold the jig.

If tenoning a wide board, or if rotating the fence, you will want add’l clamping to keep the stock against the tall fence. I’ll try to add a shot of the jig in the swiveled position to illustrate.

This old copy of Woodworkers Journal got lots of use, as it inspired at least three projects for me. I’m happy to pass it on to anyone who is interested in building the jig.

Here’s a shot from the mag. showing the jig in the swivel position…

You could also clamp through the hole.

Good job Matt. Wish I had seen this plan before I made mine as I don’t have the swivel/tilt capability.
