Building a hot rod frame is not for a novice unless you have a seasoned metalworking buddy who's built a hot rod chassis before. But it's fun! So get to it. You can build your own hot rod or even sell the chassis and then move on to another welding or metalworking project.
With that said, lets begin (by the way the chassis
and jig images are very basic and we are going to update them in a few weeks,
thanks for your patience big guy).
When looking to develop your welding
skills, even when at a very high level, there is nothing better than advanced
projects. The issue many have with advanced welding
projects is that a welder is normally at a very high standard so will only want
ot undertake projects that they feel will benefit them in honing their skill
and also building something of use.
Today we are going to talk about building a Hot Rod frame, something that many welding enthusiasts who also have a love for cars will certainly enjoy. While a hot rod chassis may look basic to the untrained eye, it is actually the back bone or spine to the whole hot rod. A hot rod chassis is the frame that holds the whole hot rod vehicle together. A chassis and a frame are pretty much the same thing so don't get confused as we use one or the other...
Without further adieu its time to get involved and show you one of the greatest advanced welding projects where you can build your very own hot rod frame.
Hot Rod Frame Jig
Before you can even build your hot rod chassis you
will need a jig to maneuver your chassis and support your building process. In
light of this we will talk about building the jig, then talk about building the
hot rod chassis.
To build a hot rod frame jig you need a few lengths
of 5cm box section and four trolley wheels. First you need to measure out three
lengths of 1.5 meters and cut out the lengths, you then need two lengths of 750
mm, you can now weld the two 750mm lengths on the ends of the three longer
lengths. This will means you end up with an image like below:
After this measure the space between the three longer lengths horizontally and cut and weld small pieces of box section between so you have the below jig:
Throughout the process ensure that the hot rod frame jig is as flat as possible. Now you can weld the four trolley wheels onto the jig, one on each corner. The idea of the jig is to give you a flat and portable work space as the hot rod frame will be heavy in weight once complete.
Hot Rod Frame:
To build your hot rod chassis you will need box
section, metal plate and a good welder, oh and you will need to follow the
You will now have a hot rod chassis that fits the
dimensions in width and length you require and that will also be the right
design to house all the vehicle parts you need, similar to the below:
To ensure your hot rod chassis has the strength and stability required you can take your metal plate and cut this into the same width and length of the front and rear box section. Now you can weld these on to the underside of your chassis at these sections, this will add strength to these areas where the most stress is caused.
Many people overlook the need for a jig and think
they can get busy with their hot rod frame without one. The problem is that
after building the hot rod frame they end up in an awkward situation as they
cannot move what they have built. At this point your chassis will be extremely
heavy and this is where you will be thankful for the maneuverable jig so you
can push the chassis to where ever you need.
