I am thinking of cutting 63 mm circles with the holesaw then cutting little "V"'s around the edge and folding them up with pliers, the hole will be in the centre from the hole saw, couldn't weld a downcomer on though as it's to thin. Thanks for the tip on the end cap I will keep an eye out for them when I go to the scrap place. My big three inch really needs centering rings before I run it again...........
