Tenonmaker MAFE1
This is my attempt to make a tenonmaker, ok I was impatient…

I heard the other day about the tenonmaker from Bridge city, and checked it out… It was Napoleon that told me he had ordered one, and was waiting now full of expectation.
So I checked it out, and could see the order cut-off date was October 22nd 2010…
So what do you do?

I made me one this afternoon!!!

The tenonmaker is a tool make a perfect fit between the mortise and the tenon.
The idea is you first cut the mortise, and then use the tenonmaker to set the table saw or router table to cut a perfect fit after.

Here it is:

Pic 1: Tenonmaker on my drawing (and my best friend ‘Tordenskjold’ Peter Wessel).

Pic 2: Parts for the project, and my kerfmakers for inspiration.

Pic 3: Using those wonderful planes I got as a present from my brother Div.

Pic 4: Cutting a thread in the hardwood.

Pic 5: Mounting the little brass parts, here drilling for a brass pin.

Pic 6: The little family of MAFE markers.

And again my contribution was ‘BRASS’.

Measure: 15×3 x 1,5 cm. Max tenon 9,3 cm long.
Brass parts mounted with Epoxy and a little brass screw in the front.

Since I finished it this night, I have not tested it yet, but I will make a little review when done, and yes; I took pictures for a blog that will come soon.


Here are a few updated pictures of the front and rear end, I filed them a little so I can get into thinner mortises, and then the rear one for elegancy…

Front end open.

The rear end with the tail up.

The rear end with the tail down.

My sketchbook drawing, not a real work drawing, but a drawing on the move…

I also made a kerfmaker the Kerfmafe handydandy, and a Blog on how to use a kerfmaker, hope it can be useful to those of you who are full of questions on this.

You might be interested in my Height-, length gauge, when you have to set the table saw depth for the cut.

Hope it can be to some inspiration,

Best thoughts and thank you to all here who inspire me, and for Napoleon to provoke me this time,

I wondered what the Pipe Smoke signals I saw over Denmark were.

Flemming, merci.
Is this the same as the kerfmaker?
Yes and NO tenonmaker is the new kid on the block in a short while, the follow up on the kerfmaker. The kerfmaker sets the saw or router for kerfs. The tenonmaker sets the saw or router for tenons.
As you can see on the photo it’s like a caliper.
Jamie, yes it took some good tobaco to figure it out…

It has that Madsfactor which to me means that it looks well made and aesthetically pleasing too. I would love to see it in use if you can demonstrate it for us.

Interesting and clever. Should I point out that you’ll need two? :) One for the width of the tenon and one for the height? The question is, can you design one so it does double duty both as a tenon maker and a kerfmaker? That would be cool. I’ve been rolling the question around in my head with no solution at the moment.

Thanks for giving me something to ponder. ;)

For those who don’t know how it works (you can order one on their website):

Yes I agree, the biggest problem is that they made two different tools, it could be made easy as one, but then they would not sell two… All you need is to make the movable caliper leg able to flip back when not in use.
Topamax, watch the video please.
Dennis, it sounds like I’ll need to make a blogs soon.
Mike, I’ll make a blog on how to use it if you dont get it from the video.
Swirt, no as I see you need only one since you need only to fit the one to the other.
The little flip is only used as a distance block against your fence when you use it, and need to be able to flip down when used to measure a mortise in the middle of a piece of wood. (As I have understod it).
Rick, hmm it seems I have to make a test blog…
Smiles to all of you, I’m always happy for any kind of feedback or comments,

By the look of your little drawings book you have as much fun drawing them as you do making them.

I’m curious where you get all of your brass fixtures. They always seem to be perfect for the tool.

Well, there is no doubt that the thing works and gets a fantastic result. A great tool(s) to have when running multiples. Thanks Mads.

Darn it – I just made a couple of Treeman’s versions of the Kerfmaker, and was enjoying the comments from friends, and then I see this TenonMaker MAFE1 !

So, its back to the workshop!

May I echo misslolly’s comment about your drawings book – the illustrations there are works of art in themselves!

BTW, I like the idea of the brass screw for setting blade width on your kerf gauge – a simple and elegant solution.
