A piece of history

Unread post by Trevorn » Sun May 17, 2020 5:50 pm

Many years ago I acquired about 10 sheets of 0,8 mm aircraft ply.
the sheets were 2,4 m x 1,2 m not the 1,2x1,2 that is the standard sheet size for aircraft ply now days.

Today is exactly 75 yeas ago the plywood was made. 17 May 1945.

I guess it must have been war surplus's, possibly material for Mosquitos.

Im not so sure about that.

The fuselage skin was formed on concrete and wood molds. The skin been a composite panel made form ply outer and balsa inner. Total skin thickness was only 11 mm. Getting a compound curve on 1/8 ply and 3/4 inch balsa is not so easy. If the skin was 1/8 ply, my guess it would have been made up of a number of layers of thinner ply, bonded together after forming. Probably with the aid of the heavy mould and steam.

Are you not referring to the formers?

Trevorn...75 year to decide to start building a plane with it.... :( So that means in the next 75 years my grandson might see a model from that piece of ply wood fly.... #-o #-o #-o #-o #-o

Jokes aside.... Just shows you the quality of that ply wood to be around for so long in that condition is simply amazing =D> =D> =D>

I bet it was not made in CHINA [-X [-X :lol: :lol: :lol:

I wonder how many people can show something like this to us...Thanks for showing it here Trevorn. How many sheets do you still have left ??? :wink:
