The rollcage fabrication began in earnest on Day 4. Jon Krellwitz (left) and Jason Rivera (right) check the placement of an over-door tube as Matt McCallum looks on. At this point, all hoops and bars are just clamped into place for test fitting, and the mock-up was done with steel tube. Once Krellwitz and LaFortune were satisfied with the cage's design, those tubes would be duplicated in chromoly. Doing it that way rather than going through trial and error using the chromoly saves 'em a buck or two.
