A good test was the assembling of the towers used in the London March on 11/30. As is explained in the manual there are a number of interconnections that should not fail and ask for special attention. The knot in the rope that interconnects the cross wires may not slip.
During assembly of the tower units, there is one place where inserting the hooks that slide into the ends of the bamboo can easily be done wrong. In case that happens, it really takes close attention to see where the mistake had been done. If not found on inspection, that hook could slide out at an unexpeted moment causing the tower to collaps.
Of course it is possible to do it all right, if people are properly instructed or have a the printed out manual available. The March was a good test how this would work out in practice.
It worked out just very good. Not a single mistake has been made.
A problem that occurred was the cracking of a bamboo. It was properly repaired while carrying the towers in the March and did not spoil the performance of the DemoUnit towers in the March in the 30th November of 2011.
James Albury reported to me how the use of the DemoUnits worked out in regard of its technical qualities. For this report see this blog.
