Making slow progress on the first baseboard

I have made some progress on the construction of the first baseboard. Hopefully the pictures will help to explain my thoughts on how I’m building the boards. At the moment nothing is fixed in place, the books are helping to keep everything upright.

All profiles have been cut to reflect the different ground levels, with additional sections cut out for the turntable and inspection pits. The baseboard top is at the bottom with the track plan on. This is so I can position the infill sections to miss any possible conflicts with turnout wiring and TOUs. Fingers crossed I’ll get them all positioned correctly. There are just the last three infills to cut and position. This will be done when all others are fixed in place in case I have made a miscalculated on the dimensions.

It might workout OK

The shed area being flat is a good start

I’m hoping to start putting it all together in the next couple of days.
