Curious joinery connection. I have not encountered this before

Greetings.

I got to know this compound on the Australian channel Pask Makes.

It is a conical round tenon connection.

Began to look for information on this type of connection. It turned out to be quite curious: from an engineering point of view, the cone connection is very reliable, with increasing pressure it only becomes denser, and from the point of view of manufacturing, such a connection requires its own tools for manufacturing.

You need to make a cone on one part and a corresponding hole in another. (scroll through the gallery)

If you make a cut in the conical spike before assembling, and then drive a wedge into it, and even all this with glue, you will get a very strong connection. (Scroll through the gallery)

Plus it's pretty pretty.

Such connections are well suited for making chairs like this, or a similar type of stool.

If you look at such a chair, it is obvious that when using it, the cone of the leg will sit very tightly in the cone hole of the seat.

What is interesting in the carpentry literature, where various joinery connections are described, I have not seen such a connection. Perhaps this is because it is still easier to make a cylindrical spike and a hole for it.

Thanks for reading. I would be glad to have your support in the form of a like and a subscription to the channel. And see other publications on the channel.

Alexander.

P.S. I also invite you to your site.
