Pack 730 Pinewood Derby Race Rules
1. Material:
Race cars shall be constructed for this event from the parts contained in the Official Grand Prix Pinewood Derby Kit (referred to below as the kit) as supplied to the scouts by the pack. Materials from the kit may be supplemented but not replaced.2. Weight: Racecars may weigh no more than five (5) ounces (total weight) as determined on the official scales during the pre-race check-in. Note: The official scale(s) will be available during the pre-registration process and again at the weight/size verification on the day of the race.
3. Wheels and Axles: The car shall roll on the wheels from the kit, or on wheels available from Grand Prix Pinewood Derby Axles and Wheels kit sold at the Boy Scout stores in Dayton and Springdale. The wheels shall turn about the axle nails from either of these kits. The axle nails shall be firmly affixed to the wood of the car body. It must be obvious to the judges that the grooves, wheels, and the nails from either of these kits are being used.
4. Size: Racecars may be no longer than 7 inches, nor wider than 2-3/4 (2.75) inches, as determined by the official gages during the Registration and Inspection. Underside clearance of at least 3/8 (0.375) inches and inside wheel-to-wheel clearance of at least 1-3/4 (1.75) inches is recommended, so that the car will run on the racetrack. Adequate clearance is the responsibility of the car builder.
5. Weights and Attachment: Weight may be added to the car and will be considered part of the car for purposes of all measurements. "Weight" is considered to be any material on the car that is not provided in the kit. All weight must be securely fastened to the car, e.g. by permanent glue, nails or screws, but not by "sticky substances", e.g. tape, or tack spray. Weights shall be passive, i.e. non-moveable, non-magnetic, non-electric, non-sticky, etc.
6. Wheel Treatment: Wheels may be polished to remove surface imperfections that could cause increased friction. The tread area may not be drilled to remove mass, however the 12 small circles within the spokes of the wheels may be drilled out to give the wheel the true spoke look. Any hub or tread smoothing/polishing may not result in substantial removal of mass, nor in reducing the wheel width from the original kit wheels. Hub coning will not be allowed. Wheels may not be machined to a beveled or canted condition and the portion of the wheel surface that contacts the track must remain parallel to the axle. The nail heads of the axles must be clearly visible (no hub caps holding graphite).
7. Unacceptable Construction: The following may NOT be used in conjunction with the wheels or axles: springs, hubcaps, washers, inserts, sleeves, bearings, hollow tubes, etc.
8. Gravity Powered: The car may not be constructed or treated in such a way that the track's starting mechanism imparts momentum to the car. (For instance, this provision disqualifies cars with sticky substances on the front of the car and protrusions, which may catch on the starting pin.)
9. Lubricants: Only dry lubricants such as graphite or powdered teflon "white lube" will be allowed for lubricating the wheels. Lubricants may not foul the track. There will be a lubrication table set up at the race. In the interest of fairness, only one lubrication is allowed before the beginning of the first heat race and then once again before the beginning of the first race of the semi-finals and finals.
10. Axle Grooves: If the original axle groves are not used, only ¼" deep cuts for the wheelbase will be allowed.
11. Extended Wheel Base: Extended wheelbase designs will be allowed, provided that the wheels, when mounted on the axles and affixed to the car, do not extend past the front or the rear end of the car. Wheels must be flush with the leading and trailing edge of the car, such that they would not extend past the starting gate pin in the track.
12. Front-end Modifications: The nose or front of the car may not be notched, cut out or sloped such that it would extend beyond the starting pin on the track.
