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.
