Fence for framing square

[Philip Davies]

Here is a fence for a rafter square, made at least 30 years ago.

Also shown, is a model roof, designed for an international competition. The competitors may face disqualification if they have to replace more than one component. I would have been disqualified multiple times! It is in front of the unnecessarily complicated bicycle shed I built, which has 3 gables, 5 walls & 8 roof planes. (And only one right angle in plan)

Pages shown are from a book by Alex Smith, "Steel Square Roofing", published 1947, by Robertson & Mullins, which another chap at college kindly lent me to photocopy.
