Steps In Doing A Street Rod Chassis Fabrication

By Laura Nelson


One important component of a vehicle which is composed of internal frames and acts as support to manmade objects for use and construction is called a chassis. Another purpose of it is to protect the parts positioned internally. The under part of the motor vehicle is an example in which the body is being mounted into the frame. At times, running gears will be included and the term for this is 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.

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.

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 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.

In order to bend top pieces of the metal into curved sides, using hammer works or clamps, weld the pieces so these will stay in its position. The small sections of a sheet metal must be cut also. During this step, be sure that welds are well grounded. But if you would prefer having it raw, it should be wire brushed and applied with primer for the prevention of oxidation.

Third, assemble all the side rails. Making a frame which is more stable and is better would definitely go beyond butt welding and this is by using hidden gussets for the reinforcement of frames with critical joints. The hidden gussets is dependent on the confirmation of frames.

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 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.
