For the strongest joint, I used 15 minute epoxy for the nose cone bulkhead gluing.
It was mixed then applied with a toothpick around the edge and down inside the dome a bit.
Keep the epoxy off the flat surface of the centering ring!
The upper BT-60 assembly was slid up the interior BT-50 tube to the top.
While the epoxy was still setting, the balsa bulkhead was slipped into the BT-50. Not all the way down onto the flat centering ring!
Leave a gap so any excess epoxy won't glue the nose cone assembly in place.
In the picture I can judge the position of the disk. If the gap space is consistent all the way around, I should get a good flush fit of the nose cone disk against the top of the BT-60 assembly.
