This weekend consisted of trimming Wills sheets on the little milling machine. Once set up it literally is just cranking them out. They are much easier to match when the edges are square.
I also chamfered the corners to get a descent 90 degree joint. Seen above glued to the plasticard supports.
Next rectangular supports to true things up and also support the road deck.
Gentle warming with a hot air gun to get the profile and the road deck is glued in.
The sides of the prototype taper slightly and I did try to replicate it, but the upper profile makes it difficult to do. So flat sided it is.
Next job is to temporarily clamps the Wills sheets in place, mark and cut them to suit.
