Put the axles in a dremel moto tool. Polish with 600 grit wet/dry sandpaper.
Put the max amount of lead 50/50 in two holes dead center over each axle.
Lubricate with silicone.

Three years of competition...
Two-1st
One-3rd


I did something similar. I participated three years. Won 1st one year, 3rd one year, and 5th (or something like that - it's been a while) one year.

Make the car wood super thin and weight placement. Buff the nails and use graphite. There was a rule against rail riders for us.

I made them similar to this. Placed first every year but one when we got second

It's so heartwarming to see a bunch of grown men busting their butts to compete in a contest that was meant for their kids.

Instead of teaching your kids how to design, carve, build, and race THEIR creation, you're teaching them that daddy will do their work for them and then hand them a trophy.

Hand your kid a pocket knife, some sand paper, and some paint. Tell them to start whittling and not to cut their fingers off.

I won more than one derby...oh sorry - my boys won more than one derby following some of the advice people here have given. The most important thing is to see what the derby rules are. Our pack had a rule that all 4 wheels had to touch the ground and spin freely so rail riding was out.

Cut out a very basic wedge shape. Get a dremel tool and carve out a lot from the bottom. Put tungsten weights as far back and up as you can while still maintaining balance. Buy some polished axles but don’t be afraid to polish them more with some super fine (3000 grit eg) sandpaper. Stick the point of the nail into your power drill and tighten it down. Take a small strip of the super fine sandpaper, wet it, press it against the nail and turn on the drill. You cannot over polish the axles. That includes the underside of the nail head.

Use a pipe cleaner to apply bore polish to the inside of the wheel where the axles go. Bathe everything in graphite.

Buy golf club head lead tape to make quick adjustments at weigh in. You want to get to 5.1 oz and then back off as little as possible until you hit 5.0 oz.

And for God’s sake, don’t let the kids touch your car!!!

If you're not cheating to win, then you're just cheating yourself.

Graphite the wheels, put as much weight behind the back axel as possible.

Sand your axles(finish nails), graphite the crap out of them, sand your wheels, insert weights on the inside of chassis as far back as possible.

Get them wheels to spin with zero wobbling. Hope for a fast lane. Aerodynamics have nothing to do with it.

It’s all about aesthetics. An incredible paint job on a car is effective on more than just pine car derbies. Now is that time to start demonstrating these life lessons with your son.

3 wheel wedge


Yes. You want a wedge with majority of weight over rear axle. The more weight towards rear allows for more speed on the flat portion. You do not want too much weight behind the rear axle it will cause the front to wobble, unless dialed in on rail running.

You want the car to run on 3 wheels touching, this reduces friction and if possible a front axle slightly bent so it hugs a rail. Even though touching a rail introduces friction, it is less painful than bouncing off rails with a wondering car.

Also the other stuff
Sand the axles like crazy and use graphite if allowed. Run at max allowed weight.

Interesting comment.

FWIW, I trimmed his pinewood block way way down with a jigsaw while he watched. Wasn't going to allow him to work a freehand jigsaw . . . Sorry

After that HE rebuilt the shape with balsa wood, glue, an exactoknife, and sanding. Learned about balsa wood, gluing wood, and re-shaping/smoothing with wood filler in the process.

He polished his own axils -- learned how to use a rototool, metal polishing, and sanding grits in the process.

He spray painted the thing. Glossed it. Then decaled it.

etc.

!st place!

Fun stuff!!
