PINEWOOD DERBY MEMORY
Outlaw Race is a Winner


At last year's derby we had so many families hanging out after the race having a good time that we thought next year we'd add an "Outlaw Race" open to anyone. The only rules were that the car had to fit on the track, not damage it, and not interfere with any other racer.

We had a great turnout with all kinds of outlaw cars. We had brother racing sister, parents vs. kids, grandparents vs. grandkids, and Cubmaster vs. everyone! Everyone was very pleased with all the competition and are anxiously waiting for next year’s race.

I entered my car, the 10 ounce "Dragonator". The car beat other cars that weighed 2 pounds or more!! And after all the years of helping my own son build cars, this was the first time we'd won anything. Needless to say my boy was a bit jealous of my Outlaw trophy which is proudly displayed in my game room.

For next year's Outlaw race the gauntlet has been laid down and challenges made from all.

Thanks for putting on a great site with good information.

PINEWOOD DERBY CAR SHOWCASE

Speed Racer - Mike McBride

I have dozens of cars, some built for speed some just to look at. This car was designed after the Speed Racer Mach 5. It has not been raced yet. It is wider than BSA specs, but will be raced in a modified class that we do with our church's men's group every year.

Winged Rail - Rick Ellis

This car raced in our church's 2009 Awana Grand Prix. It got the award for best workmanship and finished fourth for speed in the Open Division. It weighed exactly 5.00 ounces on the entry scale and has three wheelson the ground. This was my second derby. I took first in the Open Division last year and second overall. I don't mind finishing fourth as I helped build the other three cars.

Commodore Outlaw - Bill Klingler


This car is radio controlled, and will cover the track in a bit over a second. I can run it fast or slow. I can also throw it into reverse and back it up the track. It's great fun to stop it on the track, wait for a gravity car to pass, and then do a burn-out and pass the other car.

The electronics are from the Losi Mini-T RC car. The motor is an upgraded one over the one that comes with the Mini-T, and the drivetrain is built from slot car parts. It uses a 7.2V Nickel Metal hydride battery. The body is from a car kit.

PINEWOOD DERBY MEMORY
Peter's Car


Back in 2001, I was a Tiger Cub Den Leader. When the day of our Pinewood Derby arrived, all of the boys brought their cars to the inspection. You could tell that parental help was involved, but you could also tell that the boys had a hand in building the cars.

The exception was Peter. You could tell that Peter's parents probably offered little help. The block was an unsanded, rough cut wedge with a coat of gold spray paint. When we inspected Peter's car, it was way under weight. Peter went to the pit area, borrowed some duct tape and taped coins on his car until it weighed exactly 5 ounces. What a sight: rough cut, unsanded, with a clump of duct-taped coins on top. But to our great surprise, that car took 2nd Place and earned Peter a spot in the district competition. I don't think I've ever seen a boy more excited at a Pinewood Derby.

PINEWOOD DERBY CAR SHOWCASE

1962 Cub Cadet - Bill Mathews


This is a model of our 1962 Cub Cadet original by father-son team Bill and Taylor Mathews. Pine and balsa wood were used in the construction. The snowplow is cut from a scout popcorn tin.

Pink Flip-Flop & Spine-O-Mite - Kevin Willhite


This is my daughter's "pink flip-flop" car and my "Spine-O-Mite" car. She loves pink and flip-flops and I am a chiropractor. Both cars were made with Maximum Velocity parts, except the flip-flop thong which came off of a car air freshener.

PINEWOOD DERBY MEMORY
Liam's Car


I joined Cub Scouts with my stepson, Liam, last year. He was seven years old and I was the Den Leader. The den shrunk over the winter and there were only 3 boys who attended meetings. I was feeling mighty low. I was not a Cub Scout when I was young but wanted to be more involved with some fun stuff with my stepson.

We received a pinewood derby kit from Santa at the Christmas pack meeting. I did not do any research and knew nothing about pinewood derby racing. I admit that I did not even know the date of the race. There was a Pinewood work day scheduled, but it was canceled due to 30 degree rainy weather.

I went to our den meeting and information was given about the race. It was the following Saturday! I told my son that given the short notice we would not be participating in the derby. Normally, he talks a lot and is very animated, but when I gave him the news he was very sullen. I found out later that he really wanted to enter the race but never had the opportunity.

I felt bad that night. I told my wife, and she said, "You work really hard; don't worry about it."

The next morning she said, "Honey don't worry about the derby; I took care of it."

I said, "How."

She said, "eBay."

I was driven from that moment on. I took off three days from work and every day after school Liam sanded the car and I showed him how to use spray paint.

When the eBay car showed up; it was really slick compared to the one we made.

We went to the weigh-in and had both cars weighed. The eBay car weighed 4.94 ounces, the one we made was exactly 5 ounces. Liam had no idea that his Mom had bought an eBay car.

I said, "Well Liam, which one do you want to race -- the car we slaved over or the one the 'Pinewood Fairy' brought?"

He picked the car we made. When I asked him why, this very logical boy said, "Because it weighs more."

Liam's car ended up taking second place in the pack! The eBay car was not wasted. I entered the Leaders and Cheaters race and blew away every car we ran against. It was the fastest car in the pack and would have won the overall event. But, that doesn't matter. What's really important is that we did our best on Liam's car. In our minds, it was the real winner.

CAR SHOWCASE

Viper - Spencer Mortimer

This car was made mostly with a Dremel Tool. It takes a little patience to make sure you're not cutting through so fast that you actually cut where you don't intend. After shaping, the car was ready for a good thorough sanding and a paint job. First I applied a deep blue base coat and then a second lighter silver coat, taping off the areas I wanted to remain blue. The really unique thing about this car's paint job is the scales. I used a woman's fish net stocking which had to be stretched and fastened using sewing pins. After applying a yellow coat I removed the fish net stocking. I then blended the blue and the scales together with a fine tip hobby paint brush. Once that was done a couple applications of clear coat and the paint was finished.

Toyota 84c Endurance Racer - Ryan Johnson

This car is a replica of the Toms 84c endurance racer. It has not raced, but was built for show and fun. I hope to work on getting it fast for future races. But really, when this car is sitting still it looks like it is going fast!

WHOOPS!

Building a pinewood derby car is a blend of art and science. Certainly,
getting top speed from the vehicle is the science part, while making a
good-looking car requires an artistic touch. The pine block is the art
media with which you must work, and it is not always the easiest media
to work with. While working with this media, many unplanned events
can happen, some of which can be classified in the "Whoops!" category.

For example, you may be working away on your pinewood derby car,
when suddenly a big chunk of wood breaks off! What do you do? Or
maybe the paint has dried, but a big drop of paint has ran down the side
of the car! Can it be fixed?

These - and many other - minor catastrophes happen all the time to
pinewood derby car builders. Fortunately, most of these things can be
fixed with no lasting damage. To help you deal with these situations,
today's feature article will share ideas on how to deal with several
"Whoops!" situations.

THE BLOCK SPLITS
Blocks can split when too much force is applied, especially if the
block had a hidden flaw to begin with. First, to minimize the chance
of splitting:

1. Pre-insert a spare axle into each axle slot position or each axle hole
before working on the car. Then remove the axles with pliers.

2. Don't use excessive force to insert weight into a hole or cavity in the
wood; either make the hole bigger, or the weight smaller.

3. When creating a weight cavity with a chisel, use a sharp tool, and
work slowly. Don't try to pry off any more than a thin shaving of wood.

4. Don't drive a screw into the wood without first drilling an appropriate
sized pilot hole.

But if the wood does split, try one the following actions:

If the block is still in one piece:

1. Open up the crack by inserting the tip of a small flat blade screwdriver
(or another thin metal item) into the crack.

2. Put white glue or yellow Carpenter's glue into the crack.

3. Use a toothpick or something similar to spread the glue in the crack.

4. Remove the screwdriver and clamp the block. If you don't have a
clamp, wind masking tape tightly around the block.

5. Wipe off any excess glue, and allow the glue to dry.

If the block is in two pieces that fit well together:

1. Spread white or yellow glue over the entire broken area.

2. Put the two pieces back together.

3. Clamp or tape, wipe off any excess glue, then allow the glue to dry.

If the block does not fit well together, then the best bet is to start again
with a new block.

A CHIP BREAKS OFF
This is a common occurrence, especially when creating weight pockets
around axle slots. To minimize the problem, leave 1/4 inch or more of
wood around axle slots, and work very slowly around axle slots.

Axle supports/struts also tend to break off. To minimize this
occurrence, insert a spare axle into the axle slot/hole while working on
the strut.

If something does break off, here are some ideas to fix the problem. As
a bit of encouragement, a good wood glue is very strong, sometimes
even stronger than the original wood.

If the chip fits nicely into place:

1. Glue the chip in place with white or yellow glue.

2. Use masking tape to hold the chip in place.

3. Wipe off excess glue, and then allow the glue to dry.

4. Sand the repaired area after the glue dries.

If the chip is small and does not fit nicely into place:

1. Use wood putty to patch the hole.

2. After drying, sand the patched area.

If the chip is large and does not fit nicely into place:

1. Find a piece of pine and cut/carve it to fit roughly into place.

2. Glue the piece of wood in place with white or yellow glue.

3. Sand the area.

4. Use wood putty to fill in any gaps.

A HOLE IS DRILLED IN THE WRONG PLACE
This is one of my favorite mistakes. Measure twice and cut (drill) once
is the old wood-workers adage, which is an all too easy step to skip. So,
to ensure that holes are drilled in the right place, measure and mark the
drilling location. Then before drilling, re-check the position of the hole --
is the block turned backwards or upside down?

If the hole is 1/8 inch in diameter or larger:

1. Buy a proper sized dowel rod at the local hardware or craft store.

2. Cut a piece of the dowel rod about 1/2 inch longer than the depth of
the hole.

3. Place white or yellow Carpenter's glue into the hole.

4. Insert the dowel rod piece.

5. After the glue dries, trim down the dowel rod with a fine toothed saw (a
hacksaw works well).

6. Patch the spot with wood putty and sand.

If the hole is less than 1/8 inch in diameter:

1. Glue one or two toothpicks into the hole.

2. After the glue dries, trim off the excess toothpick material.

3. Patch the spot with wood putty and sand.

A SAW CUT IS MADE IN THE WRONG PLACE
If the saw cut was barely started before the error is discovered, then the
cut can generally be removed by rounding the area with sandpaper, or by
patching the cut with wood putty.

If the saw cut is significant, but does not go all the way through the
wood, then the choice is between starting again with a new block, or
including the saw cut into the design. For example, if the cut is made
such that a mirror cut could be made on the opposite side, then the cut
could be a design feature. Note how the saw cuts on the rear of this car
represent the feathers of the arrow:


If the saw cut goes completely through the car, then the design must be
modified or the process must be started again with a new block. When
deciding if the design can be modified, please note that:

1. Cars less than 7 inches long generally run slower than cars of the
maximum length.

2. Additional weight may need to be added to compensate for the
removed wood.

THE CAR IS DENTED
Dents happen very easily to pinewood derby cars. Cars get dropped, or
banged into the edge of a table. Fortunately, many dents can be
corrected.

If an edge or face of an unpainted car is dented deeply, some wood putty
can be used to fill the dent. However, if the dent is shallow, it is
oftentimes better to remove the dent by swelling the wood fibers with
water.

1. Use a sewing pin to poke several shallow holes in the dented area.

2. Apply a few drops of water to the dent, and allow the water to dry.

3. If the wood does not swell enough to correct the dent, repeat the
treatment.

4. Speed up the drying process with a hair dryer.

5. After the wood is dry, sand the affected area.

THE PAINT RUNS ON THE CAR
Getting a nice paint job takes practice, a good quality paint (mixed very
well), a smooth finish, a painting location with no wind or dust, and the
correct ambient temperature. Even then, runs can happen if too much
paint is applied.

So first, check the directions on the paint and follow them, especially the
application temperature range, and the re-coat time. Next, apply several
thin coats of paint, instead of one or two thick coats. When spraying,
always keep the can moving; don't hold it still and just spray one spot on
the car.

But when the inevitable run does occur don't panic.

1. If you plan on applying additional coats of paint, allow the run to dry
and then sand off the run. You may have to sand off quite a bit of paint,
and then reapply a few coats. Note that when sanding paint, using
dampened wet/dry sandpaper works better than dry sandpaper.

2. If you have finished painting, then cover the run with a nice decal or
sticker. Decals are great for hiding paint runs and other flaws in the car
finish!

GRAPHITE ALL OVER THE CAR
Graphite is a great lubricant, but it is also very messy. Here are a few
tips to minimize the amount of graphite that gets on the car:

1. Lubricate the wheels and axles before attaching them to the car.
Not only will this keep the car cleaner, it is also easier and results in
more thorough lubrication.

2. Wash your hands after lubricating and before touching the car.

3. Allow the paint to completely dry before mounting the wheels on the
car.

But inevitably some graphite will get onto the paint. So, here are a few
ideas for removing graphite. I suggest testing them on the bottom of the
car (or a scrap piece of wood). Paints vary considerably in chemical
content, so while these tips will work on some paints, they may not work
well on all paints.

1. Erase the graphite with a pencil eraser.

2. Rub the spot with a dab of vegetable oil on a clean rag.

3. Use a baby wipe.

4. Spray some "Simple Green" on a clean rag and wipe.

5. Spray "WD-40" on a clean rag and wipe.

6. Apply a paste wax or car polish with a clean rag.

CONCLUSION
I hope this gives you some ideas for correcting the minor catastrophes
that occur when working on your car. But remember, mistakes are part
of the process, and is a method by which we learn. So be forgiving of
yourself or your child (or parent) and move forward. Mistakes happen to
everyone, and in the immortal words of Red Green, "Remember, I'm
pulling for you; we're all in this together." (Unfortunately, the handyman's
secret weapon (duct tape) is not very useful on pinewood derby cars!)
