ASSEMBLY AND FINISHING INSTRUCTIONS
ASSEMBLE AND FIT AXLE ASSEMBLIES
(figs. 1&2).
Make two
axle assemblies (see fig.
1). De-burr parts if neces-
sary, be sure wheels face correct direction before
installing hub caps. Center axle assemblies in axle
slots on bottom of wood block. Both wheels should
clear the block enough to spin freely. If they do not,
sand sides of block until they do. Make slots the
correct size by gently taping axles into slots with a
hammer or by widening the slots with sandpaper.
Be careful to not bend the axle (see fig. 2). Re-
move axle assemblies and set aside. It is recom-
mended that you not remove the hub caps once
you have put them on the
axles. Attaching and
removing the hub caps will stretch the material
and they may pop off during racing.
DESIGN CAR BODY
1. Draw your favorite design on the wood block as shown in fig. 3.
2. Use your own design. You are not limited to
the wedge design example.
3. Plan the location of details such as fins, en-
gines, exhaust pipes, windshields and rub-on
decals as you design your car. Remember, if
you plan on adding any of
these details, they
must be made from the scraps of wood left
over when you cut out your original shape. No
extra wood can be used and no
plastic or lead parts can be
added. It is a good idea to carefully draw your de-
sign on all sides of the block.
SHAPE CAR BODY
(fig. 4)
Cut out the basic car
shape with a band saw or a coping saw. We recom-
mend adult supervision for sawing. If you use a cop-
ing saw, maintain an even cut by following pattern
