Tapered tenon cutter & mortise reamer
just for the pleasure of figuring it out

When I made my shaving horse, I made a reamer, at that time I also wanted to make a cutter, but never got there.
Since then I have seen quite a few cutters, vintage, new and other wood nerds playing with it.
But never did I see someone explain how to make one and what the difference was between those who cut and those who scrape… So I thought it was time to do something about it.

You can read more in the wee blog:

1. The set, ready for work.
2. Tapered tenon cutter.
3. Tapered reamer and cutter blank.
4. From the blog.
5. Prototyping.
6. Sweet tapers.

Hope this can inspire others to make their own tools and recycle.

Best thoughts,

I’ve been following your blog with interest. Well explained, step by step process, and it should also help to bring back some of the “old time” tools. Great project.

Beautiful job Mads. I made a reamer very much like yours for my chair seats several years ago out of red oak.
Its a little rougher in appearence but is easy to control compared to a drill operated reamer. Eric is on his winter travels to stay warm. He started in Seattle , worked his way to Los Angeles, and probably in Arizona now.
best wishes

Mads, you make the coolest tools.
I guess the way I would describe them is tools with souls, living friends to help you out in the reverie of your woodworking. These are classic “Mads” tools. Many years from now when you can’t use them anymore they cannot be sold or given away. They must be adopted. :-)

Always a pleasure Mads.

Yes now we can make these easy, I will not even think twice now when I need a new size, it will take max one hour to make a new size when needed.
Jim, thanks, yes I am sure they will come in handy.
Notw, smiles, awesome smile here.
Roger, I think so also. ;-)
michelletwo, thanks, next time you need new size, try making one now.
489tad, smiles.
Philip, makes me happy thanks.
shipwright, those were beautiful words thank you. I am really touched, especially since they come from you. I will hope that one day some of all my tools will get adopted, it is a beautiful thought.
Elksniffer, I have seen some of you and Erics work, it’s amazing, wish I could come visit you one day and work with you to learn some tricks. Just send him a mail today, I got the most wonderful one from him before Christmas. Send my warm thoughts to him and the rest of the family.
Pete, thanks, I think you have realized I love making those tools. ;-)
GerardoArg1, smiles here.
Druid, happy to hear it might come in useful, I also hope it will inspire so we will see more of these.
patron, I’m of to the toy store. You are brilliant! lol.
kiefer, do you need a drawing, I think the blog tells it all, let me know if you need advice. Guess I should make a stool now…
Mauricio, then off to the workshop you go. ;-)
Thanks all.
