To assemble and build your roll cage well, you will need the following tools – apart from a welder: a tape measure, a metal pipe cutter, tubing or pipe notcher, tubing or pipe benders, a hand grinder, and a hammer.
You may also find it helpful to have a level, a permanent marker, a carpenter angle finder, and instructions, or even a CAD drawing of your desired roll cage.
You will also need to have your safety gear – including a fire-resistant jacket, safety goggles, a welding helmet, and welding gloves. These items are non-negotiable.
