D-Day is coming this Friday. My 7th grader (Josh) is doing Co2 cars for a final school project with his class. I told him that I did those in 7th grade too. So, he ends up asking the teacher if I can make one so he can race against me. So the duel of the ages will be upon us soon. Here is Josh working on his car made from Bass wood. I made mine from Paduak, Maple and Walnut lamination. (I was trying to go for a ‘cool’ factor).

So the little booger doesn’t paint, he finds these really cool full page decal of the USA flag. I lost the cool factor!
His car weighs 3.7 ounces, mine weighs 3.8 ounces. I thought about trimming more off the back, but decided it would be more fun to race them this close in weight. (Secretly, I hope he wins.)

Josh definitely wins the cool factor! Tell me more about CO2 cars. I’m familiar with Pinewood Derby but this is a new one to me. I assume you use some sort of CO2 engine? Baking soda?

Cool stuff. Not familiar with those. Does remind me of my son in the cub scout days with the pinewood derby cars. We had a lot of fun. I on ly wish I had the shop I have now back then.

Cool looking cars. These projects are a great way to start kids on woodworking. When my boys were into
the pinewood derby, I always bought an extra kit, so I could work on my car and their cars would be the
product of their efforts alone. The oldest won the big competition with a car that might not have looked
perfect but it was his and his grin holding the trophy was priceless. Keep sharing the shop.

Looks like stability during the violent launch is the biggest design challenge, and I wouldn’t have a clue how to address that. Looks fun, though.

And how did he get the decal onto all those curves?

you both have nice cars. my 7th graders are working on co2 cars right now, all 18 of them. we are not as far along as yours. good luck to both of you. I occationally predict the winner for my students races, i am pretty good at it most of the time. my vote is for your kids car, but i really like yours.
