Got Wood?

The real way to make a strong wooden frame is to grow the wood in a
bicycle shape. Don't laugh, shipwrights have been doing it for years,
selecting tree sections naturally in the right shape. I've seen where
some furniture makers actually train saplings on forms.

Glued wood laminates can have very good mechanical properties (ditto on
the Mosquito example), oft-maligned plywood can be very high tech stuff.
Organics have a place in engineering materials, ever more in a
sustainable world.[...]

Plywood is used for pianos, high end cabinetry, etc due to its superior
dimensional stability that is achieved by varying the grain orientation
of the plies.

Yeah, people do the wildest things with plywood:

Right, and then there's a wide variety of plywood qualities. My neighbor
is a carpenter who builds concrete forms. He gives me scraps of 1" thick
stuff with 15 plies. Can't get that at a big box store.

If you have ever seen forms "blow out" during a pour, you would (wood?)
know why such heavy duty plywood is used.

I know, I've heard the war stories. There was a lot of concrete poured
during the Big Dig.
