3. Be aware of the following:
a. Cars shall not ride on any kind or type of springs.
b. No loose materials of any kind are allowed in or on the car.
c. Official number must be clearly marked and visible.
4. Review tool safety.

5. Know the various ways to prepare and finish your project:
a. Sanding wood
Wood should be sanded with successively higher grit paper. Start with 80 to 100 grit, and then move on to 150 or 220. Final sanding can be done with 320 grit paper.
b. Filling holes
Holes can be filled with wood putty, though it is better to be careful when shaping the wood to not cause unintended holes. Simply press the putty into the hole and wipe it off with a putty knife or other hard, flat tool. Allow it to set before sanding, but do sand it before applying any other finish.
c. Sealing new wood
New wood can be sealed with a grain filler. This is especially important on end-grain, as without a grain filler, the wood will absorb a finish more in this area giving the car an uneven look. It is applied with a brush and then wiped off and allowed to dry. Skip this step if you intend to stain the wood afterwards, as it will not absorb stain evenly.
d. Coloring wood
Wood can be colored by applying a stain, dye or a paint.
e. Gloss finishes
A gloss finish will make the finished wood look very shiny. Most paints can be bought with a flat, satin, or glossy finish. If you want a shiny finish, choose a glossy paint.
f. Enamel finishes
Enamel is a very tough and glossy finish. It is ideal for pinewood car designs modeled after real cars.
g. Stain finishes
Stain will color the wood but allow the natural grain to show. In other words, the wood will still look like wood, but it will be a darker colored wood.
h. Wax finishes
A wax finish is applied after the wood is stained and varnished. It brings a final polish out of the wood.
i. Acrylic finishes
Acrylic finish is a type of varnish. For the most part, it dries clear (but may impart a yellowish tint to the wood). It will lend a glossy look to the finished wood.
j. Water colors
Water colors will soak into the wood and can result in an uneven finish. The wood grain will show through, so unless that is what you are looking for, don't confuse it with other types of paint. It's best to try it on a scrap before painting your car with it. Then if you like what you see, go ahead and paint the car with it.
k. Leather look on wood
A leather look on wood can be achieved by applying two colors of a water-based paint as well as a polyacrylic clear coat. These are the steps:
- Dampen the surface of the wood to raise the grain of the wood and let it dry for half an hour.
- Sand with 180 grit sandpaper.
- Paint with the first color of water-based paint. Apply two coats if desired.
- When the paint is dry, apply a layer of polyacrylic gloss clear coat. This is to keep the next color of paint from blending with the previous color.
- When the clear coat is dry, apply a coat of the second color using a water-based paint.
- After a few minutes, blot this coat with a plastic bag to reveal the color beneath in places.
- After the paint dries, lightly sand with 320 grit paper.
- Apply a second layer of the polyacrylic clear coat.
l. Decoupage
See the Decoupage honor for detailed instruction.
m. Forged foil
Crumple a sheet of aluminum foil without wadding it into a ball (or it will tear). Flatten the foil out again and smooth it with a rolling pin. Apply tacky glue to your car, and then press the foil into the glue, shiny side up. Press the foil into all the crevices of the car. For an antique look, paint over the foil with a black, water-based paint which has been thinned 2:1 with water. Blot the paint with a paper towel.
6. Know the principle meaning of friction and how it can effect the performance of your car.
7. Know the three best ways to reduce friction on your car.
a. Axle lubrication
b. Aerodynamic design
c. Smooth finish
d. Proper wheel/axle clearance
e. Reduce wheel shaking
8. Know the three theories of weight distribution and how it could affect the performance of your car.
9. Design and build to completion the following (not previously built):
a. Basic car kit with complete exterior finish
b. Deluxe/fancy car kit with complete exterior finish and decals
c. Be creative by building one of the following: tank, submarine, airplanes, piano, ice cream sandwich, fire engine, vege-link, school bus, baby carriage, and etc.
10. Use details on your project such as steering wheel, driver, decals, and etc. as long as these details do not exceed the maximum length, width, and weight specification.
11. Participate in a club, district, or conference sponsored Pinewood Derby event with a current car.
12. Define and practice good sportsmanship as it relates to your Christian walk.
While building and racing a pinewood derby car your Christian walk may be tested. If someone needed help on their design, did you help? If you are having trouble cutting your own car, did you accept help? Did you clean up your work area so the next person had a clean place to work, or so the staff didn’t have to clean up after you? Did you have to wait a while to use some of the tools? Being patient isn’t always easy.
Jesus was a Carpenter…………Jesus may have spent many hours in a wood shop……I wonder if He helped Joseph,…..design, transfer the design, clamp the wood, cut the wood with a saw, file, sand smooth, paint, assemble. I wonder,…..how many tools did Jesus know how to use, that you just used yourself? I wonder………………..
Note: If you are planning to participate in a conference Pinewood Derby event be sure you use the correct specifications from your conference because some use different specifications than listed above.
