Combining the 2 posts abose, design#2 and the copper island theory, the fins would have to extend over the copper island (they can be brazed or soldered into place) to hold the center barb.
BTW, the center barb only needs to be held so that it doesn't flail around, it really doesn't have to be sturdier than that. Actually, the fins could have pins that point straight up, to hold the tube in place.
Comments?
Volunteer CNC'ers?
