It is Pinewood derby season for the Cub Scouts. As a father of a Weblo and a Den Leader, I hope to give your some ideas on building your car. Remember, the car is meant to be a father son project. Help your boy do as much as he can.

This year, my son decided to build a "Dukes of Hazard" inspired HMMWV (Humvee). These steps can be used to make any number of vehicles.

Step 1: Materials, supplies, and tools

It was time to gather up everything we needed.

Materials:
1 pinewood derby kit
additional wood (we used balsa, so as to minimize additional weight)
wood glue
wood filler (sandable)

Supplies:
paint
primer (optional)
sand paper (we used 120 and 220 grit dry, and 320 and 600 grit wet)
carbon paper
masking or painters tape

Tools:
saw (a band saw works great)
power sander (optional)
Dremel tool (optional, but very helpful).

Step 2: Pick a design

Now that you have the items you need, it is time to find your design. You could draw your own design, or search the internet or other references as we did.

As I said earlier, my son wanted to build a HMMWV. So, we did an image search on Google for an M-998. We found these illustrations from the military training manual for the HMMWV. We decided that a "fastback" design would work best for my son's plans, so I added a couple of lines to the design.

We then printed out our design with a length of 6.5 inches, since that size best fit our block of wood.

Note: Make sure that your design meets the specifications in the rules. You may also want to check to see if there are other restrictions imposed by your pack or counsel.
i made a more detailed one, put leds into it. it has light, but one light does not work now.
Awesome! =)
Wow that looks great none of mine ever looked that good. the wood filler is a great tip too bad I didn't know about that.

Aww, I read "pinewood derby" and thought "soapbox derby"- a ride-on wooden humvee would be something to see!
Is it loud and noisy and leak fluids like a real M988? What did you name it? Mine was named shake-n-bake it gave the gate guards a laugh when we drove up. Thats, pretty cool, let your scout wear your Kevlar on race day. Ha!

Well, my boy is calling it "The General Lee Humvee". Some of the major advantages to a wooden HMMWV are that it doesn't leak or need constant PMCSing. However, it is about as underpowered as the real thing when it comes to going up hills (though my truck was an M1038ww).
