Steps To Be Followed When Fabricating A Street Rod Chassis

By Laura Nelson


A chassis is a component that is consists of internal frames for a vehicle which serves as a support to the manmade object for construction and use. This is also used for protecting the internal parts. One example of this is motor vehicle under part which consists of a frame where in the body is being mounted. If running gears are included, the assembly will be called as 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.

This can also be fabricated and the following are the steps on its fabrication. First is to cut the sections. Make a sketch of the design then use the measurements from the sketch in cutting side rails and also the 2 elements for rear kick up. The size of tubing depends upon the horsepower, the engine choice, and the X member and K member amount. Use a chop saw for cutting tubing pieces.

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.

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.

In order to avoid these gussets to be slapped from the outside frame, these are hidden under the frame tubing. After this, it is now plug welded for kicking up the frames section. But before doing the plug welds, make sure that rail sections will be true and square.

Fourth, attach all the cross members. When starting this step, side rails must be clamped to match all the lines to be utilized in positioning these cross members. Mark all the reference points of the rails, then use these marks to install the transmission mount, from suspension components, and and the other components for mounts and brackets.
