Models and other concepts

Hack & slash log bridges.

A 20" 1/20 scale model out of oak and red cedar.

A 3 foot 1/6 scale model out of red cedar.

A 2 foot 1/12 scale model of a 40t bridge.

Simple models from popsicle sticks.

Or how about a 100 foot diameter completely free-standing dome?
Lower? Higher? Smaller? No problem.
It may be a lot of copies, but it's still made with only 2 parts.
With a fabric roof and some of the arch feet standing on a circular rail,
up to 1/3 of the dome could roll open and close.

Any height arch, up to semi-circular, may also replace a conventional roof truss
to totally open up the attic space.

Another of the many interesting features of this construction technique is its collapsability, making it suitable for semi-permanent or demountable structures such as greenhouses, tents, sheds, cabins, etc.

A flat deck variation for stable banks.
