This is our very first pinewood derby race. Kai was so excited he had high hopes to take the trophy home. I told him not get his hopes up and it is really about having fun. He was handed a block of wood that had slots in the bottom for the wheels, 4 nails and 4 wheels. I truly feel that is is about the boys and they should at least do about 90% of it. At the race it was obvious that the fathers did most of a lot of them. Kinda of sad because it really isn't fair to the ones that really did it by themselves. Kai was so excited to be able to build his very own car. He drew out the pattern then I showed him how to use the coping saw. He cute it out then sanded it..I did the final finish sanding with the electric sander. Then he painted it and I helped him to some detailed painting. Other than that he did it all by himself. He took fifth over all. He can't wait till next year!!!
