Well, here it is Pinewood Derby time, again, for our Pack. We hold the Derby in January and hand out the car kits at November’s Pack Meeting. Each year the Cubs need to create a new car. They can’t use last year’s previously experienced car. We run two sets of races. Cubs race against Cubs, and Open Class, is for everyone else. Now I will show you how I set about creating a Pinewood Derby Car for the Open Class, although everything I show will be allowed for the Cubs cars. Remember that there is no “Pinewood Derby Car Police” which will rule on how the car is created. The cars are only judged on whether or not they meet the stated, race time, requirements, as found on the paper included with the kit. Here we go!
Sand paper (Grade, 120, 140, 180, 220)
Knife or hack saw or rotary tool
Paper cups (to set the car on while being painted)
Square (to see if the axel channels are square to the car, if not, you will need to redo them)
If your Pack provides you with a kit, use that. Otherwise choose a kit. You can use an official BSA kit or ones available at local craft or hobby stores. I chose the one in the middle, except I hate the solid piece axels, so I traded for the nail axels in the kit on the left. Also the completed car, with added weights, needs to weight no more than 5oz (or 142 grams).
First thing you need to do is see if the axel channels on the bottom of the care are square to the car. If they are not, fill in the channels with wood filler. Once dry, sand it down and re drill the holes using this, a body tool. Follow the directions with the tool. Mine were straight so I didn’t have to use it this time
