So I have worked out how many baseboards I am going to need altogether = 15. With an additional number of sections to complete the top deck. So far I have 9 baseboards constructed with the same number for the top deck.

At some point I will have to get down to a DIY store and get some more 9mm ply (3x 1.2m x 1.4m or thereabouts) as I have almost run out and also need about 25m of 45mm x 20mm of softwood for the frames.

So the next plan is to start working anticlockwise and construct baseboard 15 which will go on the other end of baseboard 1. 

Many years ago when I built baseboard 1, I found I had to construct the end 6 inches on a separate board (so it would fit in the car for transport) and this will have to be detached and binned because due to the geometry of the room I have to build baseboard 15 in in its place (and also start curving the track around sooner. This is going to affect the station so might have to have a rethink at some point about how that is going to work but more than likely I will probably just redo the bridge and the pedestrian entrance and add a curve to the platform.

Most of last month has been spent on installing the loft ladder and then building and painting an inner hatch so when I am in the loft I don't fall down the hole. I have a mate who did just that, he stepped back to admire his layout....and fell straight through the hatch that he forgot was there (luckily he didn't hurt himself too badly). I had to make a second box piece to block off the draft that comes through and this fits over the top end of the ladder. The ladder itself is telescopic so it doesn't take up any space and can fold underneath the layout when its not in use. The inner hatch box is constructed in a way that means it cannot be slid if one kicks it, I am pleased with both ladder and hatch box.

I'm laying 2mm cork on the top deck - I am not intending to have ballast shoulders as its a steam era layout so just one sheet for the track area is needed. 

Sorry about the mess on the layout photo (these boards are 950mm deep to the wall. Just about reachable to the back but wish there was a bit more headroom. Top deck at this point widens out a little to accommodate 4 parallel tracks and a station platform (for heritage railway)
