Steps To Be Followed When Fabricating A 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.

Electronics and vehicle are the 2 main examples to this. The chassis of vehicles, example is street rod chassis also called as rolling chassis, are sometimes included with the running gears. The gears are the engine, transmission, suspension, differential, and the drive shaft. The coach work or under body is really not necessary for use in structure integrity but this is important for the vehicle for its completion.

Commercial vehicles are often installed with all the necessary components in trucks but the body is not included for the road operations. These are available in many different variations of design and these may only vary according to the vehicle type, specifically those that are used constantly or loaded heavily. The specialized bodies have also different versions including box trucks, ambulances, fire engines, motor homes, etc.

Fabricating these can be easily done by simply following these steps. First, cut out the sections into smaller pieces. But before this, there is a need for you to sketch the design first so that in the later parts, doing some tasks can be made easy. The tubing size will be highly dependent on the horsepower, amounts of K and X members, and choice of an engine.

Second is creating frame horn or chassis. For achieving a more traditional look of frame rail, creating a front frame horn is suggested. The patterns must be drawn first on the the paper stock for ensuring that the look is proportion according to the tubing sizes. After this, cut it. Next, cut the tubing by the use of a grinder. Some other cutting tools may be used as well aside from grinders including saber saws having metal blades.

In bending the top pieces of metal to the curved sides, use clamps or some hammer works then weld it after to let it stay in place. Small sections of the sheet metal should be cut as well. In this step, make sure that the welds are being grounded. This may not be mandatory since there are some builders who prefer to smooth and grind the welds. If these are preferred to be raw, wire brush it and apply a primer for preventing oxidation.

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 avoiding the gussets of being slapped outside the frame, these must be hidden under the frames tubing. Then after, do then plug welding so that frames section will be kicked up. But before the plug welding, see to it that rail sections are square and are true.

Fourth is attaching cross members. To start this step, clamp all side rails so that the lines will be matched because these are going to be used when positioning cross members. Rail reference points should be marked. These marks are utilized for installing components of a front suspension, transmission mount, and other components for brackets and mounts.
