The Pinewood Derby Track

This track we built for the Science
Project is now stored in our garage.
Although, several Packs use it each year. If you
would like to use it at your Pack races, check with me and I'll
add you to the schedule.
Northwest Tucson, preferably.
We can also sell the track and timer for around $750.
We have a sample race chart and some other resources if you need help
setting up
your racing brackets.
The basic design of the track was taken from the Cub
Scout track plans. The track has 2 lanes and is made with 1/2 inch black melamine with 1x2
redwood side rails. It is 30 feet from start line to finish line. (more...)
The start mechanism is a combination of several designs
found on the Internet. Sample
Start Gate Sample
Start Gate 2
The spring actuated start gate goes down fast enough
that neither car has an advantage.
The finish line gives the time in a digital readout as
soon as the cars pass the finish line. The fastest time blinks to
show the winner. The accuracy is to one thousandth of a second,
which is less than 1/8th of an inch.
The timer we picked is Fast Track made by MicroWizard. It
cost $275 with an optional battery pack. It's a little less in kit form.
The 4 ft. skid ramp at the end of the track is half an
inch high and is covered with black electrical friction tape. There
is a 2" foam pad at the end but only the fastest cars get that
far. And even then, just barely.
Car accessories aren't damaged by crashing into a pillow at high speed.
We change the friction tape regularly since it loses
it's "sticky" over time. A longer stop ramp would be better. We may build
a 6 ft. ramp at some point.
