One of the most important lessons to learn when building any fabricated component is to only tack weld parts together. As you build something you'll feel the urge to burn it in solid. But until you have made completely certain that you don't want to change anything-whether working on a rock slider, rollcage, or full buggy-it is best to just do a small solid 1/8- to 3/16-inch weld that can easily be cut out if need be. Most of the main chassis welding was done with a Millermatic 251 MIG welder.
