Snowmobiles
 

In this, the final build before the semi-finals, the Elli-vators will try and freeze out The McCarknow Clan to see who can build the better snowmobile. The course is 300 metres in diameter complete with slalom and an incline. Each team will have 10 minutes and 2 starts to see who can complete the most laps. A "start" is defined as re-starting the machine after it has stopped for any reason.
 
The McCarknow Clan are going to build a traditional...well, traditional by Scrapheap standards...ski & track snowmobile. They'll need a light engine and a good, soild front ski. Something to make a track is necessary as well. Their track will have to be large enough to distribute the weight of their machine over the snow, otherwise it will sink.  Keeping the weight down will be key.

The Elli-vators are abandoning convention. They will also use a light-weight motorbike but have 2 skis at the front with the suspension from a small car. However, in the back they're going to use an oil-drum for the rear drive. Weight will also be an issue but their untested design could be a problem as well.
