Construction of the Modules is underway and should shortly be built, ready for preparation of track.
Below is a photo of the frame construction of one of the modules. The ends are 19mm thick and a housing joint routered into them to allow the 12mm thick pine sides to be glue and screwed together.
In the future I would recommend thicker then 12mm for the sizes as splitting and strength is a real worry, although Ive been lucky.
The 4 tops have been ordered and they are 12mm thick pine sheets ready to be cut to size once modules are completed..
Now to order the track.
