Things You'll Need
Instructions
Decide on what material you want to use to make the body of your soapbox car. If you will be using it for recreation, you can experiment with cheaper materials such a wood. If the car will be used for competing there may be regulations regarding what materials can be used. Choosing a sturdy material such as steel will result in a well-built soapbox car.
Decide which type of front end or nose you would like to give your car. There are many choices such as pointed or rounded. If you are referring to a blueprint, there may be specific directions showing you how to obtain different nose shapes. After deciding this, you can start to piece the car together.
Build the exterior and bottom of the car specific to the blueprint instructions. This is when the car starts to look more like a soapbox car. Bring the sides together to ensure that your car appears the way you want it to look.
Start setting up the wheels for the car. The front wheels need to have the ability to move and steer while the back wheels will stay in a stationary position. There are many ways to set up the wheels including buying a kit or using a rope method to work with the steering wheel.
Bring all the pieces of the soapbox car together. These should include the exterior, steering wheel and chassis, and the main body including a riding seat. Once the pieces align you will need to use a strong bonding agent to keep them together. Making sure the car is built sturdily and safely is very important. Go back to the blueprint to compare your car with the suggested directions.
