I wasn't sure I'd gotten a good bond from the fin tab to the motor mount on this rocket, and I kept puzzling over how to make sure the fillets at the body tube surface weren't the whole bond.
So I carved out most of the after centering ring, which gives me access to the fin/motor tub joints and cuts a bit of weight. And cuts it where it can't help but move the CG forward.
Only wore out four Dremel heads getting there. Could have cut the centering ring this way before assembly a lot easier. Live and learn.
