In response to a question about the underpinnings of the module and how it sits on the frame work, I’ve included a couple of photos of these areas. They are, I hope, self-explainatory.


The underside of the modules are nothing new to British readers. This type of lightweight construction is well known and widely used in the UK and other parts of the world. The notch close to the outer member allows the future drop cloth that will cover the legs to be hung as a continuous piece of fabric. The middle notch is a failed attempt at aligning the module to the support structure. It serves no purpose other than to remind me to pay closer attention to whatever I’m doing.


As seen here it was far simpler to align the module where I wanted it and then glue a set of guide blocks to the center beam to hold it in position. This worked well and doesn’t add any appreciable weight.

I’ve now reached the point of the project where things become less interesting from a narrative point of view. The next steps would be all the how-to stuff about laying the track and doing the structures, using techniques we could all recite in our sleep. Therefore, I’m not going to spend  time covering them here because I have nothing new to add in terms of materials or processes. So rather than waste everyone’s time repeating the obvious, I’m going to move on to other subjects and return to this project when the situation warrants further coverage.
