Here is the current state of my "Feldbahnmodule with ship". It is a follow-up from my chronicle in
bbf.
The bridge module should be as torsion-resistant as possible. In previous modules, I had reached a sufficient stiffness with frames.

Size: 1,5 m x 1,0 m... Sufficient rigidity?
The
new module is about 2.0 meters long and about 0.9 m wide, so that all parts will fit on it.

First bridge shortly after the construction of 1901 Here there is some more information to the original.
After I initially thought about a steel frame, I came by chance on a much easier solution:
honeycomb... no, I do not intend to ask the hard-working little helpers, to give me her glue.

The principle of the comb is still used in many doors:
found at: http://www.tueren-albrecht.de/tuerenkalkulation/hilfe/images/wabe.jpgSo, such a door has been misused!

The principle you can see on the drawing above.
Currently the board is on two sawhorses, it is already so rigid in its current state, as I had hoped ... and it get more adhesions.

Recesses were sawed at the corners for the aluminum legs.
