After some serious joinery work over the Christmas period the baseboards are finished. Well almost - the cross-bearers are not installed yet as I don't want to have them under the boards where point motors are to be installed. So I need to complete the track plan, which needed to be modified because of the space available (see here for details) and because of my misunderstanding of Peco track geometery (see here for more details but basically Peco SetTrack radius 3 is too large to fit on a 600mm board).
I've also bought four sheets of Sundeala board from Alton Model Centre to top the plywood boards - I'll pin these down shortly. Anyway, here's a photo of the four boards joined up:
I thought the bullet-style cabinet makers dowels would be tricky to fit, but in fact they went in very easily (with a tap from a hammer) and work really well. Purchased from Station Road Baseboards, which so far has provided a good service (I also got my adjustable feet there).
Next step: transcribe the track plan from XtrkCad to a large roll of wallpaper on the baseboard to make sure everything will fit - I'll use point temptates downloaded from this useful site - inexplicably they are not available from the Peco web site.
