Hi? David
Fascinating that you can still find the weight of a Brunzeel plywood panel from 1978.?
By the way, the Brunzeel factory was in Gabon. He used Gabon as base wood. It is the same as
the light Mahogany variants from Asia we usually call Okoume.
Wood, also the wood veneers used for plywood, is still wood. The weight variation is easy to explain. It depends greatly
on the seasonal variation in the growth rate.?
Humidity is also playing a role. So weight variations of 5 % can be expected.
Interesting the plywood, you mention you can get in Port Townsend.?
Hi, guys. Just such information I would like to read more here.?
What other historic plywood information do you know? Which type of wood was used for the Brunzeel plywood panel, and what about other types of wood panels from back then? What is their weight compared to currently available ones? How has the usage of wood changed over time? Is it still being used as much or have synthetic materials become
A test if you like. Have a piece of wood, say dimensions 20x20mm square, type of wood, Meranti, Fir (Douglass fir ;-)), Birch length, what have you.?
Bent these over your knee till the break. Which one will break first, and which one last??
Cheers? Bernd?
