Thanks for the kind words and encouragement folks.
Vic the tracks are made up from 29 separate parts, two long strips that form the top and bottom, two short sections and the rest individual links. The kit provides two formers for the front and rear curves but I didn't find them a great deal of help. It's just a case of do a bit let it dry and then do a bit more and hope it holds together when you try to put the right curvature into it.
