Later on that night our teacher was out at canadian tire and noticed...a cutting board. So he bought it. The next day we went in with out cutting board and cut 4 pieces out of it and bolted it to our robot
and to quote one of the members from 783 . "now normally, you cut things on the cutting board, and not the cutting board itself"

We had the same issue with the turning last year. After taking off the front wheels we tried spinning castors from our car. That made it turn too fast, so we went with the back non-spinning castors off the same cart. This was again to hard to turn.
The solution: We put both. 4 sets of castors on the front. 2 spinning, 2 fix. It averaged out and worked great.
