I am looking for more ideas on how to make a Pinewood Derby car run
faster. This information would be passed
on to the scouts (and anyone else who would wants it). I have
experimented with some ideas and found them
helpful to get a fast car. I've been undefeated now for 2 years, with a
legal car. I've been passing the information
on to the scouts in the pack and I have always tried my experimental cars
before passing the info along. I do not
want to be the reason for a scout not to win because the idea had not
been tested. If anyone has any ideas that
you could pass on please Email me at LarryRadar@JUNO.com.
A few Ideas that I have worked on and perfected.
1) To balance the wheels - use a 8 penny finishing nail, file the nail
down to fit into the wheel. (place nail in drill
and use a file works great). Once the nail is the proper size for the
wheels, use a small washer followed by a
rubber washer, then 4 wheels then another rubber washer a large spring
and a flat washer and mount in drill.
The rubber washer will keep the nail head from damaging the wheel.
Adjust the spring will keep enough tension
on the wheels to keep them from turning on the nail. If the wheels turn
on the nail, the wheels will be damaged!
Use rough (60 grit) sand paper first followed by fine sandpaper. do not
apply a lot of pressure with the sandpaper
it will cause the wheels to stop and spin on the nail, thus ruining the
2) to mount the weights, I router between the axle positions (leaving
about 1/4 inch prior to the axles). This allows
me to adjust the weights (we use a lead pipe cover from the building
supply store, then cut to size and hammer
shape as needed). Use 2 brads about 2 inches long through the sides.
You can drill a small pilot hole for the
brads so they can be removed. Use super glue to keep in place once you
have found the position you want.
