[Farrout1]

At this point it is probably worth mentioning that I had never routed anything (didn’t own one!) nor ever done any scenery of any sort. I had a great teacher in Bill Schneidewind for both. Here is what routing looked like. I used six 4’x8’ 1/2” MDF (120x240cms 1.25cm) taking care to use as few sheets as possible to minimize the number of joins. I did make a few errors but it is easy to fill with wood filler and re-rout if needed. Lane spacing is same as Scalextric/ SCX track and I redid the back to back Goodwood chicanes that existed in the old track but hid it inside the snow tunnel bwahahahahhahaha!!  

For the routing you basically layout your inner lane first (there is kit with a flexible plastic guide you can buy - at old wierd herald) and then use a spacer that rests on a plastic piece that goes in the already routed slot (to mirror the other lanes) or bring them closer as your vision dictates. If you do you outer lane first you are likely to have the inner corner be too tight for a decent sized guide!
