Weird things trees.
A tree makes bark during the spring, summer, and shifts water and
nutrients up and what if gets from sunlight down.
No Idea how. No Idea why.
In the winter, the inner layer of the bark, which carried the sticky
resin, seems to solidify somehow, and the resin stops flowing.
Thats the bit that becomes wood over the winder.
The outer bit of bark thickens in the next spring and it all starts again.
Its the wood that interests us.
It seems to be made out of long bits of fibre, a bit like lengths of nylon
wool that it binds together with resin/glue.
Somehow, the whole lot flexes quite a bit before it gives up and fractures
into splinters under compression - being squashed, tension, being
stretched, or being bent. - forgotten the term for it. Getting senile.
The resin glue that holds the wood together is also heat sensitive. If we
heat it, we can get it to allow the fibres to move.
You might have seen Ray Mears straightening green sticks over a fire to
make arrows. We can use this technique to make some boat bits in two of
the methods we are interested in.
Cloth on frame, and lapstrake.
Understanding these things about wood makes using it easier.
Hopefully, you have managed to er... collect a few tea stirrers, so that
you can have a go.
