I could have bought it all from Stainless Works, but I just shopped around where I could find deals here and there to save a few bucks. What I did was tack everything together first. Then once everything is in place I will cut the tacks on the collectors and pull them off. Then cut the tacks from the tubes to the flanges and then weld each individual tube. Once those are welded I will put them back in the flange and weld the flanges. Then lastly I will weld the collector spike between all 4 tubes and then weld around the outside of the collector to finish things off. At least that is how I have it planned in my head. I would have really liked to use double slip collectors, but on this job the budget just wasn't there.
