Right, spent a good few hours there this morning and got nearly all the track markings/boarders done, so you can really see the shape.
The view from where the rostum will be (minus the blinding light

);
Im now fully aware of the size of the track and i think it is the right width and length for 1/16ths but i also think you could get away with 1/10th racing but there may be quite a few laps done
Next weekends plan:
Tarpaulin the floor inside the boarders
Build Rustrum
Get in the clay
