Reader Feedback
Here is some more reader feedback on the article, "The Dark Side: eBay Cars", issued November 2, 2005:

"I get requests all the time to build complete cars for people. I tell them that is not what it is all about. The only worse thing I can think of is buying a finished car off eBay and asking (or needing) the buyer to overnight it. No, no, no! I myself have purchased expensive finished cars on eBay, but only as a collector. I would never think of buying one to race. I know 'times they are a changing', and the pace of life speeds by. But I would rather take time and build a car with my sons, and hope for a good finish. Then, with all the money I saved by not paying top dollar for someone else's labor, take my family to lunch after the race." - Tim Hellaby

"By the way I did enjoy and agree with your article on eBay cars. The main point of the whole derby is to work with the kids, not to buy something to race." - Bart Bartkowiak

"I too am greatly disturbed about the 'dark side' of Pinewood Derby cars being offered on auction sites on the Internet. Some sellers claim to be there to help some unfortunate child with no adult or tools to create their own car. Others make no bones about selling cars so that the purchaser might win an award for looks and others for possibly taking home a trophy or two for fastest car. There is even one group that has a production line of scouts and adults producing cars and selling them on an Internet auction site , advertising them as 'Scout built, just as they should be'. Of course none of these builders are the scout that will be showing and racing the car. The only goal is beating out the other scouts. Not only is this shameful cheating, it is also tragic. These children are learning all the wrong lessons. 'The ends justifies the means'. 'Cheating is okay if it gets you the win'. 'An unfair advantage is the best way to come out ahead of the rest'. 'You can buy your way to the top.'

Where is the personal pride in knowing that as a team the adult/child did their best together? Instead the adult says to the child: 'Here is your car! It just came in the mail, I bought it for you from a professional builder on the Internet and it cost me a lot of money! But money is no object if it wins the trophies for us at the Pinewood Derby race! It will be the best looking and fastest car there!'

I am the Thunderbird District Pinewood Derby Chairman. I put on Derby car clinics for my district to teach the cub scouts and the parents the rules and techniques they need to make a Pinewood Derby car that will make it down the track in good speed. I also teach Pinewood Derby techniques at the yearly Pow Wow. My goals are: (1) not have cars come to pack races and the district race and not qualify because of rule violations, (2) get the information out to as many as possible about how to make a good running car so that it will at least make it to the finish line, and (3) to understand that winning is not everything and that building the car is the main goal. Placing well in the race and show is just icing on the cake. I stress the dishonesty of purchasing cars from other builders who sell on the Internet. Instead I encourage the teams to use the parts from the derby kits and wheel kits available from BSA. Then work to produce their own car that they can be proud of, win or loose." - Randal Veenker

Feature Article

Pinewood Derby Glossary: Part 2

Several weeks ago the first half of this glossary was provided. As mentioned then, every sport, hobby, or business has a collection of special terms, sometimes called ‘jargon’. This goes for pinewood derby racing as well. So here is the second part of the glossary. If you find a term I have missed, please e-mail them to me and I will update the glossary at a future date.


RACE MANAGEMENT

Ballistic Stoppers - Removable devices that can be placed on the braking section of the track to more quickly slow down cars.

Braking Section - A final section of a track used for slowing down cars.

Center Guide - A track type on which cars straddle a lane guide.

Elimination - A method of racing which narrows down the field by eliminating losing cars.

Garage - A stopping device generally made of foam rubber placed at the end off a track into which the cars roll.

Judge - A device (or person) that determines the finish order, but does not capture the heat times (not to be confused with "The Judge", a product by New Directions which can be equipped with a timer).

Lane Rotation - A method of racing whereby each car races the same number of times on each lane, and with the widest possible variety of opponents. Variations include Perfect-N, Partial Perfect-N, and Complimentary Perfect-N.

Laser Gate - A system which starts the heat timer when the first car breaks a light beam, instead of when the starting gate is tripped.

Side Guide - A track type on which cars rest between two lane guides.

Starting Pins - The posts behind which cars are held at the starting line.

Stearns - A method of racing which assigns cars to specific lanes for each heat. Generally this method has been replaced by 'Lane Rotation' methods.

Timer - A measuring device which captures the heat time on each metered lane. <


SPECIALTY TOOLS

Alignment Tool - A plastic gauge capable of making several measurements to better align the wheels of a car.

Go/No-go Box - A device used at inspection to determine if a car meets the race specifications.

Calipers - A device for accurately measuring thickness, depth, etc. Commonly used for measuring the diameter of wheels and axles.

Certified Test Weight - A weight certified to be highly accurate. Commonly used for verifying/proving the accuracy of a scale.

Chisel - A hand tool with a sharp beveled edge for removing excess wood. Commonly used for creating pockets for ballast weight.

Clamp (C-type) - A holding device in the shape of a 'C', used for holding the block of wood for drilling, cutting, etc.

Drill Bit (Brad Point) - A type of bit with ‘flutes’ for drilling clean accurate holes in wood. A sharp tip ensures that the bit does not wander.

Drill Bit (Forstner) - A type of bit without ‘flutes’ for drilling very clean accurate holes in wood. A sharp tip ensures that the bit does not wander.

Drill Bit (Fractional) - Drill bits measured in fractions of an inch, e.g., 1/8, 3/16, 1/4, etc.

Drill Bit (Numbered) - Drill bits measured in number units, e.g., 44, 45, 46, etc. Numbered bits have much smaller increments than fractional bits.

Level - A device to verify the evenness of a surface. Commonly used for adjusting a track, or for adjusting a test surface to be used for aligning a car.

Tips

This tip was submitted by Kyle Parrish

Most pinewood derby tracks have a center guide rail, but some tracks guide the cars with outside guides. On these tracks the outside wheel faces will contact the rails. If the car has raised lettering on the outside face, then when the wheels contact the rail, the car may lift up and slow down.

To eliminate this problem (if allowed by your local rules), sand or file off the raised lettering, and then sand and polish the outside face. Making the outside face as smooth as possible will speed up your runs!

Car Showcase

Low-Rider: Stephen & Stevie Banks


We used your Low Rider design with the Fire Starter Body Skin and the Custom Design decals. As you can see we made a 'quick start' modification To The front of the car by cutting a 1 1/8" L x 3/4" W channel and adding a paper clip. The car started rolling before the other cars. Stevie went 10-0 and became the Pack Grand Champion in his first pinewood derby race. Now we're off to the district finals, and hopefully the regionals after that!!


Snake Car: Elisa Davis


My wife wanted to enter a car in the Outlaw Division this year. So I built this three-wheeled snake. I can't take credit for the idea, as it was inspired by a photo I found on the web (if you know the name of the original designer, please let me know). The car was the fastest in the race, but was unstable. On the last heat it jumped the track, so it ended up in second place. During testing I had to add a 'crutch' (not in the photo) on the back left of the car. The crutch kept the front end from lifting too high when the car went through the transition.


Nelcom: Janel Davis


This is our version of a 'car phone'. Based on the Wing design, an extra piece of wood was crafted to fit on top. A small Velcro circle is used to hold down the top during the race. The most difficult part of building the car was recessing the hinge so that it didn't stick out the back, making the car too long. The car took 1st Place in Speed and Design.

Q&A

I recently read an article that claimed that a group added the weight inside the wheel. Have you heard of this and how beneficial is it?

Adding weight to wheels will slow down the acceleration of the car. Although a car with weighted wheels may roll for a greater distance than a car with light wheels, it can never catch up with a car with light wheels on a typical pinewood derby track.


How large does an object need to be to trigger an electronic finish line? I'm asking because I've seen many car designs that have a wire for the front of the car, often mounted high to take advantage of the starting gate drop time.

Per feedback from electronic finish line vendors, a wire may not be enough to consistently trip the line (although it can work as found out by Stevie Banks (see Car Showcase section). To ensure consistent tripping, an object of at least 1/4 inch thickness should be used. If a wire is used for the front, then you can stretch some tape (maybe metallic) across the front.


The first two years my son competed in his pinewood derby he painted his entire car and then clear coated it. The last two years we have left the area where the inner wheel hub touches the body unpainted. Which of these do you think makes a slicker surface (or faster car)?

I prefer the clear coat, but in either case, if you are using graphite as the lube, then rub some graphite on the area.
