well, i started on the rollbar, this thing's a masterpiece of booty-fab. i think it was from a fullsize truck and was cut in the middle, then the legs were shortened and cut and bent to fit a toyota. booger welds abound! but there's more...i found of all things, BONDO! it appears the "fabricator" who put this thing together couldn't bridge a gap with his welder so he just filled it with bondo
it's about a 1/2" gap where one of the supports meets the main hoop.
and my welder's taking it like a champ! ran smooth beads where i ground down some boogers on one side, and with short bursts its filling up the gap nicely. after it's filled, i'm going to grind it flush and run a few nice hot beads over it, structurally joining it.
