The bender combined with the new digital angle readout and clamp on angle gauge allowed me to produce a perfectly fitting and aligned main hoop with perfect bends.Ī roll cage is only as strong as the floor its mounted too so some 3mm cold rolled steel makes up the front footings, making these is streamlined by first completing templates out of 1mm polycarbonate.īecause I am TIG welding this cage into the car its important that I make the gaps as minimal as possible to streamline the welding process, usually this wouldn’t be too much of a problem but welding thick to thin material in an awkward position needs as much preparation as possible. We designed and printed this digital readout which made bending extremely accurate. With the bender all completed and my design finalised I started work on the main hoop, its the backbone of a roll cage and a good starting point. Just days before beginning the roll cage build I broke a few ribs falling off my bike some dirt jumps, I was extremely happy that I set this up with a hydraulic ram and foot pump, it certainly makes life a lot easier.Īfter completing a test bend and producing a bend template I was able to measure the chassis and work out the dimensions for the main hoop. In a previous post I detailed the 3D scanning that we completed on the chassis, Matt Hill got busy in Solidworks and designed the intended roll cage from my sketches.įrom here I was able to order the 1020 CDS Mild Steel tube in 44.45mm and 38.1mm in diameter, both with a 2.6mm wall thickness and got into making the structure.īefore this happened though I needed a new bender capable of the task, my trusty upright bender is a great tool but I wanted to produce roll cage bends a lot more effortlessly and after a lot of design we were able to produce our very own horizontal tube bender. Through my research for the roll cage course I learnt a lot on design and function of a roll cage. When I was first figuring out this roll cage design I looked upon many different motorsport disciplines, I wanted this chassis to have the ability to compete in any form of motorsport in the FIA world. To make my life a little easier I made up a chassis JIG that allowed the car to be moved about the workshop and also elevate the chassis to a hight that made getting in and out a lot easier. It seems fitting as this car is culmination of many things that I have learnt over my career, after removing it from a 10 year slumber its been treated to a lot of time and effort and the roll cage is something that positions it firmly for its racing future. 2021 is off to a flying start, the S15 roll cage is really starting to take shape so I thought I would check in with you guys and give you an update to the progress I have been making on it.Īs you have probably figured this isn’t my first roll cage but it’s definitely the best I have ever produced.
