PINEWOOD DERBY
1. Materials
The block of wood, the wheels, and axles supplied in the Official Grand Prix Pinewood Derby Kit must be used. The car must be new each year.
2. Dimensions
The car width shall not exceed 2 ¾ inches including the wheels
The car length shall not exceed 7 inches (the original length of the block of wood)
The car height shall not exceed 3 inches
3. Nose Design
Nose design may not be smaller than ½ inch centered.
4. Weight
The weight of the car shall not exceed 5.0 ounces (141.75 grams). Movable weights are prohibited.
5. Wheelbase
The wheelbase (distance between the axles) is 4 & 3/8 inches on-center from axle-to-axle.
The wheelbase may not be stretched or shortened.
There are slots provided for axles in the original block of wood.
New slots may be cut to ensure that axles are square to the body but must be 4 & 3/8 inches on-center axle-to-axle and no less than 1 inch from the back of the car.
New holes may be drilled through the sides of the block to ensure that axles are square to the body but must be 4 & 3/8 inches on-center axle-to-axle and additional inspection holes must be drilled in the bottom of the car so that the "point" of the axle may be visible for inspection.
6. Wheels
Only the black wheels that come in the Official Grand Prix Pinewood Derby Kit are allowed and the BSA lettering on the sidewall of the wheel must be visible.
Wheels may be sanded FLAT as to be made as smooth as possible.
The tread or contact width between the wheel and the track shall remain flat and at the original width of the wheel provided in the Official Grand Prix Pinewood Derby Kit.
Rounded treads or "V" treads will not be permitted. No shaping of inner or outer hubs is permitted.
No washers, bushings, springs or ball bearings will be permitted on the wheels.
All four (4) wheels must make full contact on the track at the same time.
Only two of four wheels may have the same number. No matched wheel sets are allowed.
7. Axles
Only the Axles that come in the Grand Prix Pinewood Derby Kit are allowed.
Axles may be deburred and polished.
Axle shanks may not be grooved or thinned.
Axle heads may not be angled.
8. Lubrication
Cars may be lubricated prior to registration with powdered graphite only.
No liquids, oils, sprays, greases, or silicones etc. are to be used as lubrication on axles, wheels, or any part of the car. These types of materials will ruin the track and are not permitted in any Pinewood races including the Mad River District Finals.
9. Attachments
Creativity is encouraged but parts detaching from cars mid-heat can affect the race in a negative way hence all attachments to the car must be firmly and permanently affixed. Inspectors will touch and grasp to see if any such parts are sufficiently attached.
Body kits may be used but check your final dimensions (Length, Width, and Height) to make sure that the finished product conforms.
10. Passing Inspection
All cars must meet all specifications to achieve a "Pass" status.
Inspectors have the right to fail any car that does not meet all specifications.
You'll be given plenty of time to work on your car to correct anything that may have caused it to fail inspection.
11. Sequestering
Once a car has passed inspection, the car and owner are registered into the Grand Prix Software. A registration card is provided and must be filled out. Please make sure the information is accurate. All owners will be able to name their cars and a picture is taken which is shown during the heat on race day. The car is then placed in custody of the LMES Pack 15 Pinewood Derby Officials and sequestered until race day.
1A. Handling the Car
The cars shall only be handled by the starter and appointed pit stewards.
No car may be removed from the race area until all racing is complete.
LMES Pack 15 will keep the cars until the Blue and Gold event at which point the cars are displayed and superlative voting occurs. All the cars then go home with their owners.
2A. Re-Inspection
The Pinewood Officials reserve the right to have any car fixed or modified for compliance reasons.
If a car is found to be out of compliance with the rules prior to racing, even if the car previously passed inspection, the owner and Akela will be notified and given the chance to repair.
Although the system provides many points of inspection, and many eyes, something could have been missed. The idea here is to be fair to everyone and not let someone run a car with a clear advantage over the others. Should this occur, please explain this to your Scout.
At this time the Scout and his Akela must make the repairs together with the supervision of a Pinewood Official. Once the car has been modified for compliance, it will be turned back over to the Pinewood Official to be re-weighed and re-inspected. The Scout and Akela will not have access to the car again unless it is deemed damaged during the race (see rule 3-a).
3A. Damaged Cars
The car may be worked on only if damaged during the race.
The car may be worked on if it has jumped the track into another lane.
The extent of damage requiring repairs will be determined by the Starter.
If deemed necessary, both the Scout and his Akela may repair the car. NOTE: This may delay a future heat. Once the repairs are in the "delaying" stage, the Scout and his Akela are on the clock for five minutes and once the time expires, the car will be eliminated from the race and a replacement car is used.
Cars that develop obvious defects such as lose wheels may be repaired, reweighed, and rerun. Only one repair is allowed in the interest of fairness and time and must be repaired by the Scout and his Akela together with the supervision of track official.
After the repairs are made the car must be inspected for size, weight, wheel spacing and the rules as indicated.
No car may be re-lubricated during any repairs under the 3A Damaged Cars rule.
4A. Heat Re-Run
If a car 'jumps the track', the heat will be re-run.
If a problem with the software or an error on the Officials behalf occurs, the heat will be re-run.
If a car loses a part or parts that affect another car during the heat, the heat will be re-run.
If for any other reason the Track Officials feel a heat should be re-run, the heat will be re-run.
A heat re-run is unfortunate but necessary to keep things fair. Please be patient and explain to your Scout why it is necessary.
5A. Disqualification
A car that 'jumps the track' three (3) times will be disqualified.
A car deemed beyond repair by the Track Officials will be disqualified.
A car removed from the track illegally will be disqualified.
A car found to be out of compliance or has an integral part creating a clear advantage will be disqualified.
6-A. Replacement Cars
Replacement cars can be presented at inspection as a back-up for any car.
It must clearly be deemed and labeled the back-up and will be kept un-numbered.
LMES Pack 15 will provide three Replacement Cars for cars damaged under 3A Damaged Cars Ruling
