Two year build and almost finished. The track is constructed from free polystyrene foam boxes – very easy to work with. The setting plaster is very hard and has made it very solid. It will run a 6 car power base from Scalextric, but is only set up for 4 cars.
The total build cost is AU$4,000 – PLUS many hundreds of hours work.
