Some time ago I built myself a Midland Fog mans hut from a works drawing dated 1918, but I had a few issues with making it hinge, the Midlands huts didn't have doors but were designed to fold down when not in use.

Well today I revisited my original work and applied the little gray cells, by changing the materials I have been able to make a robust pivot based on a 1/32" rivet.

So now not only can they be up in use but folded down.

Coal bunker as a little project next.
