3. At the same end,
draw a 5/8" x 1-1/2"
notch 1" from the
top of the sheet
(Figure 2).
4. Draw Line C 2-1/2"
from the other end
of the same sheet of
balsa wood (Figure
2).
5. Using a hobby knife
or a coping saw, cut
out the notch drawn
in Step 3.
6. Locate the other sheet
of balsa wood. Draw
a line parallel to and
1-1/8" from one of the
narrow ends. Cut along
the line to produce
a 1-1/8" x 4" panel
support member.
7. Using a cool-melt glue gun, run a small bead of glue along one of the 4" edges of the panel support member
and attach it firmly at Line A (Figure 3). After it is in place, run an additional bead of glue on each side
of the joint between the chassis and the support member.
Wheels, Gears, and Axles
Installing wheels and gears on axles can be difficult. The gears and wheels should fit snugly to the axle and provide
power to the wheels. Your teacher has troubleshooting tips on what to do if the gears and wheels are not snug.
Rear Axle Assembly
1. Deburr the axles by brushing the ends against sandpaper. This makes it easier to push the axles into the wheels.
2. Detach Gear I from the gear font. Using a sharp knife, carefully remove any plastic flashing between the gear teeth.
3. Place the gear on a table. Insert one of the steel axles into the gear. Slide the gear 1-7/8" from one end of the
axle. It should be 3-3/8" from the other end of the axle (Figure 4).
4. Slide two nylon spacers onto the axle, one on each side of the gear (Figure 4).
5. Place one of the rear wheels flat on a table. Keeping the spacers in place, insert one end of the axle into the wheel.
Slide the axle into the wheel until it is flush with the opposite side of the wheel.
6. Lay the other rear wheel flat on the table. With spacers still in place, slide the free end of the axle into the wheel
until it is flush with the opposite side of the wheel.
7. Stretch a wide rubber band around each of the wide wheels. These act as tires and provide traction for your
vehicle.
