The front axle: Two pieces of 1metre timber mounted to the front of the drum. The gap between them is equal to the height of the 15mm equal T pipe fitting. You need to mount this securely and centrally at the front, more stress is imparted as the loads feed into the drum and axle in a smaller area than at the rear.
The 15mm T is drilled to match the bike wheel axle, we were able to adjust the wheel axle so we could off set the wheel and allow more thread to be supported through the T piece.
The control arms mount on to the wheel axle, its made from the steel bar. The bar is heated so it can be bent and twisted.
Steering: It’s a simple Pitman Arm arrangement. The M8 threaded bar is used as the steering column. A hole is drilled at the bottom front of the drum and the bar threaded through. It is held in place with nuts and washers.
The Pitman arm is made from the steel bar and is positioned using nuts, once in the right place these are welded to lock the arm in place. The steering wheel is made from more steel bar with a nut welded to it and again once in the right place welded into place (although you could use lock nuts).
An old broom handle is screwed to the steering wheel bar to make it more comfortable to use. Steel bar is used to create the track rods.
An old plastic chair was sacrificed and screwed into the cart so that the driver is a little more comfortable.
The brake is simply taken from an old bike and mounted on the rear axle frame and operated via a simple lever.
We hope this project helps in your plan to build a ‘car’ for your kids. Now go ahead and let your creative juices flow — customize and improve your plastic barrel car with your unique and wonderful designs! :)
