All the usual precautions were taken when Norm started the final welding. He added more tack welds first, and skipped around with the welding to prevent too much heat concentration in any single area. "I would say my longest weld was 3/8-inch at a time," Norm says, and he did some hammering along the seam to relieve stress and correct distortion. This was especially important on the long, flat portions of the hood.
