In the style of James May, revisiting toys from his childhood, I’ve been playing with my Meccano again.
Before I get as far as building the new modules for real I wanted to make sure my calculations were right in practical way. I needed to be sure that a module using the maximum possible height and width dimensions would actually go through the loft hatch. That’s when I came up with the idea of using Meccano to build a wire frame skeleton of the module to test the theory.
Although there is a lot of play and distortion in the finished skeleton, it is stable enough to prove that the modules, when finished, will go through the loft hatch. Some modules may necessitate the removal of the handrail on the ladder, but that’s a minor inconvenience, compared to having the layout permanently stuck in the loft.
