Welding time!!
First pictures were of prototype to test welding on, here is the actual pieces to be welded together after getting the welder set up for this thin .040" tube, now the hard tideous part comes, TIG welding it together. Only thing missing in the pictures is the end plugs for the manifolds, they are a press fit and once in won't be easy to get out. This is the step I have been dreading, TIG welding thin aluminum is no easy task
