I’ve been quiet for a while. I hate switching my computer on. It disturbs my tranquility.

But! To the chair. I wanted to make a very rigid-looking piece. Almost militaristic. Martial. No softness.

I started with a beech plank. There was some nice quarter-sawn grain revealed on cutting it up, so that’s why I went for the angled m&t joints in the last picture, so no end grain would interrupt the visual flow.

The double tenon joints the central spine to the front legs’ crosspiece. I hoped this wouldn’t compromise its strength.

Then I got to the back legs. Criminy! How to join three pieces together without getting ugly? So I created this interlocking joint (picture 4) where the central spine slides into the back legs’ crosspiece, and then the backrest slides down to lock it all together.

There’s not much to add to that story, but I have more of the build at https://imgur.com/a/Ueywrx4 if you’re interested.

It’s not entirely practical, of course. My stuff seldom is. I think your bum would get numb sitting for any length of time. But I suppose, in woodwork, the destination isn’t really as important as the journey.

Thanks for looking!

Pretty slick locking joint in the center.

I am glad you mentioned the comfort factor. I was going to ask. It looks cool, but not comfortable.

You pushed way beyond my joiner level, love the workmanship on the joints. Looks a bit like Japanese joinery.
I could sit in another chair and admire this one for quite a while.

Strange and wonderful chair. I concur looks like stiing on a rock would be better on your bottom. I’ve seen this type of stick chair before, always wonder if it will support much weight?

” in woodwork, the destination isn’t really as important as the journey”

I couldn’t agree more.

Thanks for posting.

Very thought provoking. Fantastic joinery!


But I suppose, in woodwork, the destination isn’t really as important as the journey

I suppose, as a cabinet maker, my customers would disagree….

Wonderful joinery and “artistic” design.

Functionality as you indicated is questionable and in-spite of the great exercise in joinery I doubt it is really stable; especially laterally.

ditto to all on the magnificent joinery in your chair,those joints are pure artistry in themselves.the design is way more cool than im sure it is to sit on very long but as you say its not made for practicality.i certainly admire your skils and congrats on top 3.
