Building your car

-
Only use the wheels and axles provided
in the kit. (No. 17006)
-
Wheel bearings, washers and springs
are prohibited.
-
Only dry lubricant is permitted.
-
Cars must be free-wheeling. (No starting
device)
-
Accessories such as steering wheels,
driver, fenders are allowed as long as the car remains
within the weight and dimensions listed below.
-
Wheels and axles may be debured and
sanded, but only as long as the original design is maintained.
(No excess sanding.)
- This is in no way a complete set of rules. (Some rules
may vary depending upon your pack.)
-
Make sure the grooves are a perfect
90 degree angle to the car body. (use a square or a
piece of paper)
-
If the grooves are not square use two
hacksaw blades side by side to redress the grooves.
(Use the edge of a square as a guide to keep your cut
straight.) 
- Tap the axles into the groves, leave1/4" out. Do
this one at a time removing each with pliers until all
four have been done. (It's important to do this step because
it's easy to damage the grooves and better to happen now
then after you've completed the car.)(See figure 2)
- Draw your favorite design on the block.(You can trace
the block on a piece of paper then draw your design, cut
it out and use as a template. This is great because you
will get your drawing even on both sides of the car.)(See
figure 1)
- Cut your design out using a coping saw or hack saw.
Have an adult help you with any carving needed. Then finish
the details using sandpaper. (Start with a heavy grit
like #80 or #100 then finish it off with a finer grit
like #240.)(See figure 3)
- Add any weights necessary to bring the car including
wheels and axles up to 5 ounces. (Its best to build the
weight into the design. Drill holes and insert fishing
weights.Or you can wait and use stick on weights latter.)
(WARNING=Most weights are made of lead
and are poisonous to humans, always wash your hands after
handling lead. Keep contact with lead to a minimum.)
- Seal wood with a sanding sealer then sand with a fine
grain sand paper.
- Apply 2 coats of fast drying paint.When paint is dry
sand lightly and add a final coat of paint, let it dry
thoroughly.
- Add any other details now.(accessories, detailed painting)
- Rub car with a rubbing compound to smooth finish.
- Add a coat of auto wax and rub to a high gloss.
- Add your wheels leaving 1/32" from car body. Pre
lubricate with dry lubricant only! Check your car to make
sure wheels turn freely and that all four tires contact
the ground.(See figure 4)

TIPS: Check your wheels
and axles. Most of the time the wheels will have excess
pieces of plastic left over from manufacturing. Axles
will have sharp pieces of steel under the head. These
will slow down the car and can be taken off as long as
you don't modify it in any other way.
