Supplies
Holding the pinewood derby requires that a number of things be
brought together with no exceptions.
There are three events which must happen: weigh-in, dry run day, race day.
The supplies for the dry run and the race day should be the same, so
we'll discuss those together.
Weigh In
The weigh in night is typically the pack meeting just before the
race night. Because the race takes a while to run, the race is not
held during the pack meeting.
Once the cars are weighted in, the kids are encouraged to check
them into the race officials. This means that the cars can not
be tampered with before race time, thus avoiding another weigh in
on race night.
At weigh in, you will need:
- Several long tables (the ones from the cafeteria work nicely).
Note that the graphite used for lubrication stains everything
(including the tables), so be careful, and have cleaners.
The graphite should only be used outside, and attempt to use
care when the cars come back inside.
- 2 or 3 scales with sufficient accuracy to measure 5 ounces.
- 2 or 3 power drills. If the drills need power cords, bring
those as well as a plug strip. Bring at least a 5/16" bit.
- Fishing lead in 1/4" diameter. This lead fits easily into
a 5/16" hole.
- Several pairs of diagonal cutters or other nippers to cut the lead.
- Hot melt glue gun with glue sticks, and a power cord.
This is used to hold the lead in place.
- Graphite in squirt tubes. This must be applied outside.
- Paper towels and spray cleaner.
- About 6 to 8 people to man the various stations.
- Boxes to hold the checked in cars.
We use boxes with 4 slots. These boxes are used during the
race to have cars available, in the right order, for the gate
keeper to load onto the track.
- Little round stickers. These stickers are attached to the
top of the cars. A car number is written on each sticker.
The first digit is the den number, and the second is a
"child within the den" number. If you use the digit 0 to
represent den 10, this allows up to 10 dens with ten kids.
- A manifest of all scouts in the pack. When cars are checked
in, record the car number.
- It is never a bad idea to have duct tape, a couple of screwdrivers,
and other basic tools around.
Notes about weigh in:
- Cars are not required to be five ounces, they simply cannot
be over this weight.
- Graphite stains. Keep it under control or outside.
(Have I mentioned that before...)
- The kids worked hard on the cars. Keep that in mind as
you drill holes in their cars to put in weight.
- The first station that the kids line up at is the table furthest
from the door which has the graphite station. The first station
examines the car for legal items:
- Is the car the right size? Too tall and it won't fit under
the gates, too wide and it will interfere with other cars?
See that it has clearance for the car guide on the track.
- Does the car use the given wheels and axels? No washers
are allowed in the cars either.
Next the people at the first station weigh the car, and put enough
lead with the car to bring it up to 5 ounces. Note that when the wood
is drilled out to insert the lead, this will leave the car a little
light. Adding hot melt glue brings it closer to a wash.
- The second station (a little closer to the graphite door) is used
to attach the lead to the car. Use a 5/16" drill bit to make a place
to put the lead. Use hot melt glue to secure the lead to the car.
- The third station (outside) is to add graphite to the wheels.
Regardless of what you do, this will be a mess. If a child doesn't
want graphite, mention what it is for, but don't force the issue.
Attempt to make sure excess graphite won't fall off the car onto the
gym floor when the boy goes back into the gym.
- The last station is car check in. Put a sticker on the car with the
number assigned to the boy. Check his name off of the race
manifest.
Dry run and race night
During the dry run, you can have mistakes. On race night mistakes
are to be avoided. There are lots of things to bring together here.
If at all possible, run through the full race schedule on the dry run
day. This allows people to become familiar with how the race runs,
keeping cars in the appropriate lanes, operating the computer, etc.
You will need some dummy cars for this, as you won't want to use
the kids cars for testing the track and procedures.
- The race track.
This is typically stored in the closet at the end of the gym.
- The stands for the race track.
These are probably stored in the area where pack flags and
Mr. Spiffy are stored.
- The electronics package for the track.
These are probably stored at somebodies house in the hope
that they are not destroyed at the school.
- All of the supplies used for weigh in, although you probably
only need one scale, one drill, and one hot melt glue gun.
- Duct tape.
- Black electricions tape.
- Yellow ribbon to mark the "keep back" zones. People will
attempt to move right up to the track and lean on the track
if you let them. This will mess up the track, so use chairs
and ribbon to keep people back from the track. Allow
room for a runner to bring the cars from the end of the track
back to the start of the track.
- One of the cafeteria tables for placing the cars and awards.
- An MS-DOS computer.
- A printer with a serial connector instead of (or in addition to)
a parallel port. An HP500 works nicely.
- Paper for the printer. Have about 25 pages available.
- About 35 feet of 25 pin cable to connect the race track to the
computer. One end of the cable should have a male connector, the
other end should have a female connector.
- About 15 feet of cable to connect the serial port of the computer
to the printer.
- A plug strip for the computer and printer.
- An uninteruptable power supply for the computer.
Yes, this is not strictly required. How many fates do you wish to tempt?
- An extension cord for the computer and printer, and another for the
track electronics. The track electronics only needs a two prong
cord, the computer may need a three prong extension cord.
A 25' extension cord is fine for the track electronics,
a 50' cord is needed for the computer.
- A manifest which shows whose cars are in which races. This
must match the schedule in the computer.
- A working PA system. This may be a portable system, or
simply a mike plugged into the gym's PA system. Know how it
works.
- The board which holds the current race number. If the numbers
are preprinted, they should go up high enough for the races on
the manifest. This board helps keeps everybody on the race
team as well as the audience keyed in on the current race.
- Poster paper with each child's name and four columns. Fill out
the names before race time. Have posters for run offs and the final
race as well.
A number of people are needed for the race day.
- An announcer. This person will be talking all night long.
It is convienient if they can add excitement to the race
by saying whatever is appropriate. They must also fill the
dead air time when the rest of the race team is busy getting
cars loaded or dealing with minor emergencies.
- Someone to load cars into trays for launching.
This person has a race manifest which says which cars
are to go into which lanes for a given race.
The board which indicates the current race number is important
here. Note that for dens on less than eight cars, there
will be a delay as cars are brought back from the bottom of the track.
- Someone to start the races. This person loads cars into
the correct lanes, and when everybody is ready
releases the cars. If there are any oddities about the
running of the race, this person should signal the computer person and
the announcer that something failed.
This person should have a race manifest and double check that
the cars they are loading corresponds to the current race number.
- Someone to run the computer. This person ensures that
the computer is ready to monitor a race, that the race
number of the current race number board is accurate, etc.
- Someone to log the results. This person (and their helper
if available) transcribes information from the printer
(which is a permanent log)
or the screen to large poster paper per den.
The only information which needs to be logged is the time
for each car for each race. Once the den is complete, average
times will be printed out which should go into a final
column, and the 1st, 2nd, and 3rd place should be identified.
- Someone to transfer the cars from the end of the track
to the start. This person will be moving alot.
- A couple of gophers. These are always needed.
