Designing

With using the information gathered about the features that both F1 cars and land speed record cars have, a basic 3D model was created on Autodesk 2012 and then it was refined after the use of virtual wind tunnels.

During the making of the F1 car in the Denford Milling machine, one side was milled perfectly but on the second side, the machine went off track and cut through the block. The machine was reset but the problem occurred again. The problem was finally solved and it done this due to the feed rate being too high so it started skipping instructions. I continued to mill the car and once it had finished I mixed sawdust and PVA glue to make a putty that was light and then filled the hole. At this stage the car weighed 24 grams. The car was then sanded smooth with 800 grit sandpaper and then painted gloss black. The car was then sanded with 800 grit sandpaper again to take off the shine of the black paint and to create a uniform surface for the second coat to be applied. Once the second coat had been applied the car weighed 34 grams. After deciding which design I liked best, I made a stencil of flames to spray in orange onto the car. The stencil didn't work as planned so I sanded the car again and then sprayed two coats of orange.

The wheels need to be light and durable in order to accelerate faster so plastic would be the perfect material for this. I found some old used wheels that had the axle supports broken off and used them by improvising to make them work in limited time. I used a 2.4mm filler rod used in welding as it would be strong enough to support the car.

The first side was cut but on the second side, the speed was to fast so it skipped instructions.
