Pinewood Derby: XXX

It is not necessary to attend a workshop. You can build your car at your own home. Note that our workshops provide power tools only (band saw and belt sander), which Scouts are not allowed to use according to BSA guidelines. The workshop also has the official scale for ensuring your car weighs 5 oz or less.

In our workshops, parents work with their child to design the car and discuss how to build it, but use of cutting and sanding tools are strictly for parents.  Painting and other decoration are done at home. 


Car Design Info: Important!  Our Pack rules do not allow 3-wheeling, bending axles or shaving wheels.  Also, no pre-made cars. Each Scout will build and decorate his own car.
