2010 Pinewood Derby - Daniel's car

Daniel had his 2nd Pinewood Derby race about 3 weeks ago. His car did better this year compared to last year as far as the speed is concerned. I believe we shaved off about 1 second on the time. Here's Daniel's Pinewood car this year.

We traced the design on the side of the pinewood block.

The other side of the block

Started cutting the design using a coping saw. 

I told Daniel to change the design a bit.

Cutting is still going on

Done with the cutting. Working on the filing/sanding next.

Didn't have much pictures for the filing/sanding. 

We used a flat file and a medium and a fine grit of sandpaper.

Here's the sanded wood block.

The edges are smooth. 

We decided to use quarters this year as weights. We're putting 3 quarters on top.

I don't have any router so I just cut the circle pattern using a craft knife.

Here's the 1st one of the 3 holes.

We used super glue to attach the 2 quarters.

Applied wood putty to cover the holes. 

I told Daniel that I'll just put a few more quarters at the bottom.

Here's a couple more places to put quarters.

Super glued the quarters again.

Daniel wanted his car to be yellow (similar to last year).

Weighed the car and we have to add more weights. 

Here's one more quarter.

Added 2 quarters in total.

Covered them with wood putty and sanded it after it dried.

Painted the bottom and attached the wheels

Daniel attached some stickers.

Initial weight of 4.87 ounces

Additional stickers

Full view of the car.

Added a few weights on top. 

It seems that my weighing scale is not accurate.

Weight is 142 grams. We'll target this weight next time.

The limit is 141.7 grams.

I'll be posting Daryl's car next. He wanted to join the pinewood derby race this year with a red car.
