I have seen a few rockets where the motor mount, centering rings, and fins are assembled, filleted, then slid into the body tube after extending the fin slots to the end of the body tube.
I haven't seen any closeups or discussions on the process.
I assume a short piece of tube coupler, or body tube with the thickness of the tube cut out and reassembled is used behind the aft centering ring to restore rigidity.
Does anyone have experience with this? It seems like it would make for perfect motor mount to fin internal fillets, at the cost of internal body tube to fin filets, but that could be covered by strong external body tube to fin filets.
I just wondered what people thought about it.
