Pinewood Derby

March 31, 2018

Good Shepherd Episcopal Church
715 Carrell St, Tomball, TX 77375 - Bollinger Hall

8:00 am - 2:00 pm

The pinewood derby is one of the most popular and successful family activities in Cub Scouting. Pinewood derby cars are small wooden models that Cub Scouts make with help from their families. Then they race the cars in competition. The cars are powered by gravity and run down a track. Every boy can design and build his own "grand prix" car to enter in the race. Win or lose, Scouts will take pride in having done their best. Scouts learn craft skills, the rules of fair play, and good sportsmanship—things they will remember for life.

The cook-off is open to all current and previous Scouts and Scouters.




Car Check-in

Scouts who placed first, second or third in their rank in their pack's pinewood derby can participate in the district pinewood derby. The Scout must be present to participate in the races.

Car check-in will be on Friday, March 30, 2018, from 7:00 - 9:30 pm. There will not be any check-in on Saturday morning. If you cannot make the check-in on Friday night, please contact Doug Wylie at dwylie00@yahoo.com.

Cook-off

The cook-off is open to all current and previous Scouts and Scouters. Competitions will be held for best entree, best side, best dessert, and best overall. Separate competitions will be held for youth and adults. Competitors provide their own cooking supplies. Fires must be off the ground; charcoal may be used. Camp stoves are also welcome. Non-cooking can also be prepared and is a great idea for Cub Scouts entires.  Judges are needed.

The entry fee is any donation to Friends of Scouting.

Cooking may begin at 8:00 am and judging will be conducted at noon. There will be some cool surprises for the winners.

To participate in the district pinewood derby, a Scout must have placed 1st, 2nd or 3rd in their own pack race as attested to by the pack unit leader. 

All cars must pass inspection to qualify for the race.  Following are the inspection points: 

  1. The car weight shall not exceed 5.0 ounces. The official race scale shall be considered final 
  2. The overall length of the car shall not exceed 7 inches
  3. The overall width of the car shall not exceed 2 ¾ inches
  4. Clearances: 

a. The car must have 3/8” clearance underneath the body
b. The car must clear center guide rails with 1 ¾” clearance between the wheels
c. Fender flairs with less clearance are acceptable as long as the center rail width clearance is maintained. 
d. Weights are preferred to be inset in the body or on top of the car to aid in a safe stop at the end of the track. 
e. No part of the car or attachment to any car, which is metal, pointed, sharp, and/or jagged, may be capable of contacting any part of the track. 

5. Wheel base: 

a. All cars must have a wheel base no less than 4”, with the two rear wheels being positioned directly across the body of one another and the two front wheels being positioned directly across the body from one another. 

6. The front end: 

a. Height – Depending upon the track, the font of the car may rest against a short starting pin. Therefore the front bottom of the car which rests on the pin is no higher than ½” above the track. 
b. Width – The front end must be at least ½” wide in the center of the vehicle to make contact with the starting pin. 
c. Absolutely no part of the car body, wheels, or attachments may protrude in front of the starting pin. 

7. The wood provided in the kit must be used. The block may be shaped any way that is desired. Additional woods may be added to the kit if desired, but the overall width and length requirements will still apply. 

8. Wheels: 

a. Use of ONLY Official BSA Scout Grand Prix wheels is allowed. 

All lettering/numbering, both inside and outside, must remain complete and be visible. The fluting and other BSA markings on the outside wheel area must remain visible. Outer wheel surfaces may be sanded shaved, or polished to remove surface imperfections, mold casting burrs, and correct off center wheel bores. Outer wheel surface must not be reshaped in any way in an attempt to minimize tread contact or alter aerodynamics. Tread surface must be flat and parallel to the wheel bore. Coning the hubs and truing the inside tread edge is allowed. Tread width may not be less than 7.5 mm. You may add material such as glue, fingernail polish, or table, to the inside of the wheel to aid in balancing the wheel, however NO MATERIAL MAY BE REMOVED FROM THE INSIDE SURFACES OF THE WHEEL. Minimum diameter of wheel is 1.16” to maintain the ridges of the outer edge. 

b. Wheel Bore treatment is allowed including polishing and/or tapping. Wheel bores may not be filled and re-drilled to alter bore diameter or to achieve better fit with the axle. c. The following wheel modifications are PROHIBITED: 

  •  Rounding of tread surface/wheel edges 
  •  Grooving, H-cutting or V-cutting 
  •  Altering of wheel profile 
  •  Narrowing the tread surface, other than truing inside tread edge 
  •  Drilling sidewalls 
  •  Hollowing, sanding, or otherwise removing or modifying material from inside the wheel 
  •  Filling of any wheel surface with any type of material 

9. The axles supplied with the kit must be used. They may be polished or lubricated. 
10. Approved lubricants include (but are not limited to) Graphite, Teflon, Nyoil, and Krytox. Over-application of lubricant which results in excessive shedding onto the track is not allowed and no wet lubricants will be permitted on the car prior or during the race. 
11. Wheel bearings, washers or bushings are prohibited. 
12. The car must not ride on any type of springs. 
13. The car must be freewheeling, with no starting devices. 
14. No loose material of any kind, such as lead shot, may be used. 
15. The car body may have no moving parts. 

Each car must pass inspection by a race official or delegates before it will be allowed to compete. The race official or delegates have the responsibility to disqualify those cars that do not meet these specifications. 

Additional Rules and Regulations: 

  1. If, during a race, a car leaves the track without interfering with its opponent, it shall be considered to have ended its heat at that point. 
  2. If a car leaves its lane, at his sole discretion, the track chairman may inspect the track and, if a track fault is found which probably caused the initial violation; the Race Official may order the race to be rerun after the track is repaired. 
  3. If, during a race, no car reaches the finish line on the track, the car which went the farthest in its lane shall be declared as the heat winner. 
  4. If, during a race, a car leaves its lane and, in so doing, interferes with another racer, then the car at fault shall be declared to have lost the race heat. 
  5. Any car loosing wheels or any part that prevents it from running may be repaired after the inspection and weigh in. A race official may authorize repairs when damage is caused by collision with another vehicle or object or if the vehicle is damaged in transport by a track official. The repair must be performed prior to the next heat and on the premises. Only after the car is repaired will the heat be run again. If the car cannot be repaired before its next race starts, that race will be delayed to allow time for the repair. 
  6. Construction of all entries must have begun after last year's races. 
  7. Only one car may be registered by any person in the pinewood derby. 
  8. Only one lubrication is allowed before the beginning of the first race. 
  9. Details such as the steering wheel, driver, decals, painting, and interior detail are permissible as long as these details do not exceed the maximum length, width, and weight specifications.
