Although I originally learned to weld over 30 years ago in college when my team was building a Mini-Baja race car, I never did anything with it as one of the other team members picked it up faster than me and ended up doing all the welding. Welding has changed a great deal since then, so it’s time to relearn anyway. To that end I designed a swing set for my daughters, which I’m building with the same techniques I’ll use to build the Formula 1000 car, including the TIG welder, plasma cutter, tubing bender, and chassis jig table.
