Simple Steps On How To Do The Fabrication Of Street Rod Chassis

By Laura Nelson


The chassis is one of the components of vehicle which has an internal frame that serves as the support for the construction and use of manmade object. It is also being used for protection of internal parts. An example for this is an under part of motor vehicle which is consist of frame in which the body will be mounted. If there are running gears included, its assembly would be referred as a rolling chassis.

Two main examples for this are the vehicles and the electronics. A chassis for the vehicles like street rod chassis or rolling chassis are involved with running gears and these gears would include the differential, engine, drive shaft, transmission, and suspension. An underbody or coach work is not necessary for integrity of a structure but is still necessary so that vehicle will be completed.

For the commercial vehicles, this is consists of all the needed components of trucks, not including the body, for its operation on roads. The design of this may be different depending on the vehicle, specifically if the vehicle has a heavy load or is used constantly. Specialized bodies also have different version of this which includes fire engines, box trucks, motor homes, ambulances, etc.

The fabrication can be done easily by following these simple steps. First is cutting sections into pieces. But before doing this, you may need to make your sketch first for designs so it can be easy for you to follow the measurements when cutting the side rails and rear kick ups. Tubing sizes depend on engine choice, X and K members amounts, and horsepower. The chop saw will be used in cutting the tubing pieces.

Second is to create the chassis or frame horn. In order to achieve the traditional looks of frame rails, create the front frame horns. Draw first the pattern on a paper stock to ensure that looks are proportionally correct based on the tubing size then cut it out after. Next is cutting the tubing using a grinder, but other kinds of tools used for cutting may be used a well such as a saber saw with metal blades.

Use hammer works or may be clamps if you will bend the metal, top pieces to curved sides then weld it after for making it stay to its position. Also cut those smaller sections of metal sheet. When doing this step, see to it that these welds are grounded. Other people would choose for it to be raw, so raw types must be applied with a primer to prevent an oxidation and must be wire brushed.

Third is assembling side rails. To make a better and a more stable frame, aside from doing a butt welding, you may also use hidden gussets for making the critical joints of frames be reinforced. These hidden gussets depend on a frames configuration.

For an avoidance of slapped gussets from an outside frame, hide these under a frames tubing. Then after, plug weld it to be able to kick up a frames section. Before doing plug welds, be sure that all rail sections are true and are square.

Fourth is to attach cross members. Start by clamping the side rails so that lines are matched since these will be used for positioning the cross members. Mark the reference points of rails. The marks will the used for the installation of transmission mount, components of front suspension, and some other brackets and mounts.
