Each year your club has borrowed a
pinewood derby track or resuscitated an old clunker. You've tired of
this hassle and the time has come to own your own new track. The
question you face is 'Should we buy or should we build?'. Given the
necessary investment in dies and tooling it would be rather impractical
to try and build your own aluminum track. For a wooden track, though,
it would seem simple enough to buy a sheet of plywood at your local
lumber yard, gather a group of parents, and follow the Scouting
'How-to-book' instructions.
The first problem you would
encounter is at the local lumberyard. The types of plywood commonly
available are not conducive to the construction of a quality track. The
best cabinet grades sold will have birch face panels with softwood
cores. The softwood cores will allow the fasteners to loosen,
egg-shape, and depress the face panels. After your first session you
will end up rebuilding this track, too. There may be some solid core
'Baltic Birch' or 'Finnish Birch' plywood available but unfortunately
this only comes in a European size of 5'x5' sheets rather than the
traditional USA size of 4'x8'. The simple facts are that the way lumber
is distributed; the 4x8 sheets of plywood that we purchase with glass
smooth maple faces and seven interior laminations of solid alder are
only available by special order in bulk quantities from the largest
wholesale distributors. If you did gain access to the same stock we use
it is likely that the price you pay for a small quantity would be
exorbitant.
If you did obtain the material you
then face the hurdle of accurately machining the stock. Who among your
group has the floor space, table saw (with the appropriate plywood
blade), accurate fence, power feed, and in-feed and out-feed system to
handle expensive 8' sheets of plywood? Affixing the car guides may seem
simple; and it is using our custom clamping jigs, alignment fixtures,
and pneumatic staplers. Mechanical staple guns will not suffice.
Nailing or screwing will skew the alignment.
Wood vs. Aluminum
As with many choices this is one
based on aesthetics. Our 'Freedom Series' aluminum track is by nature
more durable. Our 'Classic Series' wooden tracks have been described as
beautiful pieces of furniture. Both series carry a lifetime guarantee.
All of our tracks are built to the same specifications in the Cub Scout
Leader How To Book.
We robotically drill all the holes
and mill all the slots in the tracks on a custom configured 5' x 10'
gantry CNC milling center and various CNC driven three axis vertical
mills. The joining plates, starting gates, and elevating legs are all
processed on a CNC driven three-axis turret punch. We can guarantee
clean, accurate holes with positive no-fuss alignment. There is bound
to be someone in your group who claims to be able to do this with a
hand drill and router. As I mentioned before, after one season you will
be rebuilding this track, too.
Remember, the investment you make in
one of our tracks will be paying dividends for decades. It is likely
that your grandchildren will race their cars on the track you purchase
today. We are professional craftsmen, we take pride in our work, and we
stand by our products.
Sincerely,
Micro Wizard
