2014 Bing Design AAF Dayton Pinewood Derby Car

2014 Bing Design AAF Dayton Pinewood Derby Car

Bing competed in the 2013 AAF Dayton Pinewood Derby race at SAA in Kettering. Our Harbinger of Destruction tank did pretty well. This year, in the spirit of art and design, Bing is doing a watercoloring kit car after a series of ideas and pseudo-voting this car was the staff favorite.

Roger produced a 3-D car rendering of what he envisioned the car to look like when completed to get some thoughts from staff, and then he started the car construction…

Here are the construction photos…

The above photo is the car cut down to nearly 1/3 of its original block height and after using my new drill press and trusty Wizard ‘Dremel’ tool and sander.

Some more sanding above, and the car was pretty much ready for paint.

I had the car painted at Jim’s Body Shop between the picture above and the one below, but failed to get a shot after getting it from the shop.

Jim’s Body shop has done some vehicle work for my co-worker Joe Gauder and me. They helped us out last year with our ‘tank’ derby car too. If you like a trustworthy body shop that is good on prices, check Jim’s out!

I was hoping to use some lead for weight in the areas where the paint is to go on the top side of the ‘paint kit’ but I needed too much weight after cutting the car down so much. So I made a series of dado cuts in the wood on the bottom AFTER paint was on the top. Thankfully the lightweight pine did not crack!

I sanded the steel smooth and then used my Wizard to sand down the grooves in the wood, and then put the steel and wood together with wood glue and some quick-grips.

Once the wood was drying, I got my drill to file, sand, and burnish the axles smooth where the factory crimping was. Not sure why these kits have the crimping on the nails. I guess to just make it tough on the Boy Scouts and Cub Scouts to compete? Makes it tough on us AAF racers!

5 days to go to race night…
