In my continuing effort to get everything welded onto the frame so can paint it, it’s time to build the floor pan. SCCA rules allow the floor pan to be a stressed skin, so this one fully welded around outside and to all crossmembers. To anyone who wants to learn to weld better, I recommend welding a floorpan. That’s a lot of welding. None of these pieces were laser cut– templates were made in plastic sheeting, transferred to sheet steel, and cut out with an angle grinder. Wear hearing protection. And eye protection. And lung protection. And heavy gloves up to your elbow. Angle grinders can mess you up.
