The Japanese use no glue at all, and are very proud of it.

All of these joint types are used, somewhere.

In buildings, strong joints, which are intentionally complex, to dissipate
earthquake energy in the joint friction. There are no triangle braces or
plywood shear sheets in Japanese building frames.

In furniture, beautiful joints. Japanese furniture can be taken apart and put
back together without damage.

And, as others have noted, they have many wooden buildings that are 1,000
years old. Glue would be goo or dust by now.

There are plenty of wood structures standing after 600 years. One just
has to be in that country and see the old buildings.

The Old English "Eastburn Manor" - is still standing and in good shape.
It was there a very long time ago.

Cultures in Japan and China and some other places have existed and they
stayed in the same area / site for much of or all of the time.

Thank you for the excellent pdf, Larry! The complexity of their
style is mind boggling. The math on pg 88 through the finished
corner hip roof joint on pg 95 is completely amazing.

Obviously a lot of glue area on some of those joints, but I gotta ask:

How many of those joints actually exist outside of a computer?

I don't think Mr Robinson whispered "plastics" into Ben's ear until 1968?

I guess - no glue on many of them.
They exist on the fancy furniture and boxes and whatnot.

The craftsman might work on the project for months. We do the same in
hours or days.

We use strong-ties and lots of nails, the Japanese use precision
workmanship. Some buildings built their way have been in continuous use
for more than a thousand years. How many built with Strong-Ties and
Loctite will still be standing after that span of time?

When I was living in the UK, used to visit a pub, "The Royal Standard of
England" that was 900 years old at the time ... built ten years before
the Battle of Hasting in 1066.

Took this photo circa 1963:

The notable thing, besides its age, was how short the doorways were.
Folks were obviously shorter in that part of the world before the
Normans invaded. LOL

If I had been exposed to this at an early age it would have been all
over for me ... I'm not into Zen, but I could get lost, mind and body,
in doing that kind of joinery, but it would have to be on my terms, IOW,
to the exclusion of everything else.

Reminds of when I taught myself to code when I was much younger ... get
lost in for days, or sometimes weeks.

Includes drawings with measurements and some strength analysis. Many
lock with no glue at all.

Danged if I know. What I do know is, they burn great in a firestorm.

I was a programmer for 40+ years. Thought I'd never do it again after I
retired. Then I discovered Arduino - now I write code for my model
railroad :-).

they also have taken joinery to the next level with cnc

the joints are too complex to do by hand

interestingly they used gluelam beams and cnc to create large spans
that require no load bearing supports that would normally break up
the space

think it was a music auditorium they built using this technique

the beams were curved also which added to the complexity of the joint
and led them to cnc milled joints
