Log/Lin Pots

[Refugee]

I am pretty sure that the Paxolin type material the track formers used to be made from was pretty soft when it was new and that they were wound flat and then bent round before it fully hardened. At a later date the material becomes very brittle and brakes up easily.
I am pretty sure that is how they used to be made and it also may help to explain why the material becomes so brittle with age.
