I never had much luck doing a double flair on steel line using the $25.00 help tool they sell at parts store.3/16 is the worse I end up breaking the small adapter in the kit.Well as they say you sometimes can't see the trees for the forest,this AM I called my parts guy he says bring it down I can flair it for you,I never thought they did that, didn't even charge me.They do advertise machine work done so gonna give them all my future businessIn this case read the phone book lol

 

Cool, I'm glad you got it done.
