Today for he Co2 car project I have made my base template for my car. I went and then made changes from the template so it fits in with all the criterias.

Today, I have started to shape my car into the form I wanted it to look like. I used the arc making tool to make my car more rounded so its aerodynamic.

At the beginning of a new week I wanted to make my car more efficient. So I put my box in the front of the car where the beans will go. So it would be more efficient in the wind tunnel I added a little windshield so the air would be pushed over it.

Today, I have continued to try to make my car more efficient by making it aerodynamic. I made the back more rounded and added a small spoiler on the back.

Today I have added where I am going to put the wheels so I know where I wanted to put it. I made the front end a little lower than the rear end so its facing down a little bit.

Today, I have thought about a redesign making my car skinnier in the back so its more aerodynamic. At the end, I have made my car shorter in height and more rounded in the back.

Today, I have tried to make my wheels on SketchUp. I failed miserably and was not able to succeed. Every time I pulled my wheel around the circle, it would not line up. I tried to fix that all of class.

Today, I have finished my design on SketchUp. I added the eye screws. After that, I have started to make measurements on the balsa wood. I only got to the front end, and the axle holes.

Today, I have continued to make marks on my car so I can only cut once then be done. I have been having trouble with my curved lines so to try to make it accurate, I make marks about every half inch then connect the dots. I did that so when I cut, I can sant the arches.

Today, I first finished my measurements on the car. Then I made my base cuts with the band saw. So now I can sand my car down to size.

Today, I used the chisel to make my hole in the car where the beans would go. I noticed that the hole is not that big compared to my sketchup. But it is measured in millimeters. After I made the hole, I started to sand my car and got to 120 grit sand paper.

Today, I finished sanding my car until it was smooth. It took a lot longer than I thought since you notice all the imperfections in the car and you need to keep sanding until you fix them.
My Measurements:
Height with no wheels: 50mm
Length: 209mm
Width at axles: 40mm
Axle distance to bottom of the car: Front: 9mm Back: 9mm
Axle hole from front and rear of the car: Front: 39mm-168mm Rear: 157mm-51mm
Wheelbase: 115mm

Today, I have started to paint. I only managed to put on one layer of paint today.I am using a gold color as my base coat. This is going to be the color of my stripe. I am going to try to make the last coat dark blue or dark red.

Today, I continued to paint. I finished putting two more coats of gold paint on my car. Then I started to put red paint on my car. I was only able to put two coats on instead of three and you can still see some gold.
