Got another good few hours under our belts tonight (my mate who is helping me will be signing up soon, so i cant take all the credit anymore

)
After experimenting today with how wet/dry the clay has to be able to smooth the track out we think we have cracked it!
These pictures are just the start of the main straight and also shows the banked last corner which will be a good feature i think.
Yes i am aware its quite stoney but i will try to sort it out over time
