boing, first, use the red. It's holding strength is twice that of the green. As to the lip, that's OK as long as the tube dia. is larger than the bore and not the other way around. A flush fit is always desirable but not always achievable without extra work on the bore. Problems rear their heads when the dia of the bore exceeds the dia. of the tube. Tubes get blown out... It isn't pretty. But yours sounds fine. If you find holes in your pattern you might talk over with your smith extending the existing forcing cone in the tube back into the bore, getting rid of the step and increasing the forcing cone length at the same time. This can really help with the smooth constriction of the column. George
