Had a blast doing this for a fundraiser at work.
This was my attempt at a pinewood derby car. Full disclosure, it was slow as hell lol. Huge lesson learned is bearings sound good on paper but are actually have a ton of drag. Rest of the car design worked pretty well. If I did it again I will redesign it to not have bearings and probably a small pin or something like that. Also the frame wasn't stiff enough to keep the smaller wheel off the ground.
Used 3/16 rods I cut to length for the axe
