Traditionally, you can find bumper cars at the local fair and amusement parks. Children enjoy these rides for their ability to drive a car while young and to crash into other cars. Bumper cars operate through an electrical current delivered through a metal ceiling or metal floor. Building a bumper car can be very educational. You can build the bumper car using some materials at home. However, most of the materials are preconfigured and you must purchase them through a manufacturer.
- Skill level:
Things you need
- Mini-car steel chassis
- Pneumatic rubber bumper guard
- Fibreglass body frame
- Cushioned seats
- 4 car batteries
- 8 diode rectifier connectors
- Nylon pickup mounting bracket
- Floor pickup rectifier
- 16 puller bolts
Slide the fibreglass frame over the chassis. Secure the body frame by screwing in the bolts with the wrench.
Install the 4 batteries to the back of the frame. Attach each diode rectifier to the floor pickup rectifier. This establishes the energy current throughout the bumper car.
Install the nylon mounting bracket. Mount the bracket to the back with bolts. The bracket is what draws electricity from the ceiling and powers the battery.
Install the seats into the vehicle. Screw the bolts into place to secure the seats.
Wrap the rubber bumper guard around the bottom of the car. Locate the hook on the chassis and secure the bumper pieces together by latching both ends to the hook. This provides a secure seal of the bumper guard.
Place the bumper car onto a metallic floor. Press the pedal to operate and test.
