As they say in the carpentry business, “measure twice, cut once!” Despite all the best effort and machinery, you might not get the precise cut that you asked for. I found out about this when I was testing the module electrical connection with my mentor René. Each module base was supposed to be exactly 1080mm long. The Märklin C-tracks are exactly 1080mm but the module itself is exactly 2mm short. It may not seem to be a problem but it is an obvious gap.

I thought about the gangway between two carriages. It serves as a damper and an enclosure. I applied the same concept to close the 2mm gap between the 2 modules. When the modules are screwed together, the tracks will fit but leave that obvious gap. I used 2mm thick Finnish cardboard from Architecturebedarf.de

2cm strips on 3 sides and bottom of module end serve as “gangway” and “damper” to close the obvious gap between modules (Foto: Jimmy Low (c))

Instead of covering the whole end module, I just taped 3 sides with 2cm wide strips to cover the visible parts to visitors namely the both sides and top. A short strip covers the bottom middle part.

Now, all the visible 2mm gap is concealed. Problem solved!
