Thanks Dutch, I appreciate your advice! I'd had that same concern so I've flanged the top and bottom of the part that attaches to the rad, actually double layered and flanged/soldered, and intend to do something similar with the circular to square joint. I also have some small copper rivets that I may add as well for extra insurance! The copper and rivets were left overs from the range hood I'd built a few years ago when we built the new house on the farm. There was no way I could afford to buy one, so I did what us rodders do best.
