I.
CAR
A. The car
must be newly built for the current Cub Scouting year
(after August 1, 2004), and must be the car that placed
in the pack race. The car should be substantially built
by the Scout. Parental supervision in the construction
of the car is encouraged. Any cars with wet paint or
dripping glue will be disqualified.
B. The body
of the car must be made from the block of wood provided
in an official B.S.A. PINEWOOD DERBY Kit (Cat. No.
P1622). Wheels may not be designed to ride upon the
guide strip of the track. If the front of the car is
designed to gain an unfair advantage at the start or
interferes with a fair start, the car will be
disqualified. No part of the car should extend beyond
the starting line.
C. Only official B.S.A. Scout
Grand Prix wheels and axles may be used.
Axles must be firmly attached to the car. Axles may be
deburred and polished. Wheels may be slightly sanded to
remove casting burrs. This light sanding is the only
wheel modification allowed. Beveling, tapering, thin
sanding, wafering, or lathe turning of wheels or axles
is not permitted. “Speed wheels and axles” are not
allowed.
D. Mold projection defects on
wheel treads may be removed by sanding. The wheels may
not be sanded to enhance performance, ie, no reduction
of tread width or beveling of wheels allowed. If
excessive wheel sanding is detected the car will be
disqualified. The wheels must be attached to the car
with the axles provided in the kit. No cars will be
accepted in the PINEWOOD DERBY where bearings,
washers, springs, or spacers are used as part of the
wheel assembly.
E. Lubrication
- only graphite powder may be used to lubricate
wheels. (Warning - other lubricants may damage the
plastic wheels and keep them from turning freely.) Once the car is weighed in, it may NOT be
re-lubricated.
IMPORTANT:
For the safety of all participants and the
regular users of this building, any graphite must be
applied ONLY in the designated work area. No graphite
may be applied anywhere else inside the building.
Doing so will disqualify entrant.
F. Length,
Width, and Clearance -
·
The total weight
of the car may not exceed 5 ounces.
The readings of the official scale will be
considered final. No
loose material will be permitted of any kind in or on
the car. Anything
falling off the car after the races start will not be
reattached—with the exception of wheels and axles.
Wheels and axles may be re-attached.
·
The maximum width
of the car, including wheels, may not exceed 2.75
inches. Minimum width between wheels shall be 1.75
inches so the car will clear the guide strip. Wheel base
(distance between front and rear axles) may not be
changed from the official kit.
·
The maximum length
of the car may not exceed 7 inches.
·
The motion of the car may not be
mechanically aided (motor, springs, rubber bands, etc.
are prohibited).
·
Minimum clearance
between bottom of the car and track shall be 3/8"
so the car will clear the guide strip.
·
Maximum height
shall not exceed 2.75 inches in order for the car to
safely pass under the finish line.
The Pinewood Derby
officials may disqualify any car that in their
determination is not in compliance with the spirit of
the PINEWOOD DERBY race.
