This may seem familiar to some of you,this was a project by Jeff Miller that was in Popular Woodworking Feb.2014 #209. This is apparently an old tool that was mainly used in France by early chairmakers. After seeing this I knew I had to make one.The tenoning frame holds the work and creates a perfectly flat surface for the saw to ride on. This little jig cut perfect shoulders on tenons with ease. You do all your layout as you normally would with a marking knife or scribe then use a jig to line up these marks to the cutting edge of the saw and cut. The spacer block that is used to line the saw up is a block of wood with a washer filed down to a cutting edge attached to its edge at the exact height as the lowest point of the saw blade. Jeff Miller used a Lie Nielson saw blade for his saw, well that wasn’t going to happen for me. I just bought a kobalt tenon saw from Lowes for around $14, and used the handles from on old plane.The whole thing is walnut except for the base of the saw which is maple.
If you do tenons on curved parts or angled shoulders or if like me you sometimes have trouble even on straight tenons you will love this tool.

Very cool Paul! Is the jig post just lagged to the frame from the back? Perfect fixture for the tail vise!
Looks like a great bench buy the way.

Interesting. I wouldn’t mind seeing a video if you have time to make one.

What a fine old jig. Paul. It reminds me of my miter jack
There must have been an immense number of these wonderful jigs around before the electric motor came along and shuffled them off to the Dusty old store room.

Thanks for the nice comments ,
I think the older I get the more affinity I have for hand tools.

woodcox, yes that is exactly how it is attached

mbs I’ll see if I can make a video and post it

Paul , That is just what I thought when I first saw it, I think the magazine came out just after you posted the miter jack. That miter jack is on my bucket list :)

Awesome !! I wish I had that much walnut laying around.

Japanese pull saws (Ryoba: ) have rip teeth on one side and crosscut on the other. Might be a fine addition to your arsenal.

Very nice build
You can see a version of this in use at:
(the tenoning sequence starts at about the 5 minute mark).

‘boîte carrée dite “à tenons” ‘ item 571 on page 40 of the catalog of the “Forge Royale” pointed to in the Lost Art Press blog of May 19, 2014.

Thanks Sylvain, That catalog was really interesting to see. The video was pretty cool also, the guy on that band saw had cutting to a line mastered. Now that I have seen the “Bilboquet” in action I might consider making one. It makes laying out the tenons look pretty easy. All these links were definitely worth a look.
