I started on the driveshaft loop/crossmember today. Using a press I oval a 2” section of 6” pipe and hammered the top half to match the shape of the driveshaft tunnel. With the loop clamped in place and using a 15” contour gauge (a must have tool) I made two cardboard pattern for the crossmember. With the cardboard center section of each pattern as wide as the square tubing (2”) I was able to lay it over the tubing to get a precise line to cut with the plasma cutter. I still need to make the pattern for inside the tunnel above the loop before I can weld it to the floor.
Thanks
