Attach the wheels and axles to your block. Position the fenders
so that there is equal spacing around the wheels. The bottom
of the fender will not be flush with the bottom of the block. Glue
the fenders to the block with a good wood glue. Secure in place
with clamps or rubber bands.
If your design has the fenders rising above the car body at
any point then it will be easier to glue the fender on the
body after the fender has been shaped.
After the glue has dried, remove the wheels and trace your design
on both sides of the car. Cut with a band saw or coping saw.
Round the edges and smooth the rough spoets with sandpaper or a
file.
The fenders may cause some cars to exceed the 5 oz maximum weight.
You can remove weight by drilling holes in the bottom of the
car near the front.
