Before any one else piles on screaming "Let the kid do it!..A$$ hole!"My son is only 6 so he cant use power tools etc. I plan on him designing and painting the car. I'll help with all the speed work, polishing and weights and stuff, the things he could care less about, or I may send the whole thing to Gray so neither one of us has to deal with it

I'm not gonna pile on...there ought to be age group handicaps and a specified amount that parents can be hands on for each group...obviously a 6 year old can't build what 14 year old can but this seems more like dad against dad...the kid is just along for the ride (pun intended)

OK, I'm late to the party, but we can call it reference material for next year. Take the axles, put them in a drill and file off the flashing. Then go to 120 grit sandpaper, 220, and 440 grit wet. Follow up with pumice or some polishing compound. Weight is important, but so is friction or lack thereof. Soap may slow you down, use a graphite molybdenum mix. Also sand off any high points on the wheels and any flashing on the edges there.
Weight. We put it on either side of the rear axle. Two years ago we put it too far back and with a light front end the car wiggled all over the track. Make sure you are right at 5 oz, you can use the modular weights on the bottom to fine tune it. The scout shop also sells axle spacers and an alignment tool to make sure the wheels are straight. As a finale, my son made the regionals, as did I when I was a Cub. We both got clobbered by the obsessive engineer father/son cars there, but we made a respectable showing. |

I put the axles fo the boys cars in a lathe and turned them darned near needle fine.
Wheels went in next and got a point contact patch w the track. One wheel was turned small. Effect made them 3 wheeled cars. Race day, they filled "hubcap" area with powdered teflon and added file marker dots as hubcaps to hold the teflon in. Trophies are downstairs.

I entered quite a few as a kid. I carved my cars with a pocket knife and sanded them smooth. I also found out what works: add weight! Not in the rear! I drilled holes in my cars, melted fishing weights and poured the hot lead in the holes. Lead is easy to work with, you can sand it smooth, and remove tiny amounts to meet the maximum weight allowed. You want this weight up front on the car. I tried it in the rear one year and it's definitely better up front. Seems to follow the stop better when it falls to start the race. Good luck, those things are a lot of fun!

Now that he's a Boy Scout, my son's troop decided to have an untimate Pinewood derby. Weight limit was 2 lbs, that's not easy to fit into a small block of wood. He built a pickup truck and we put steel bars in the bed to get to the limit. He beat every car except the one with a motor. If he had only told me motors were allowed...
