On the right is a dry fit of the BT-55 tube. The tube slides over the lower ring.
The marks on the BT-55 tube must align with the cut lines on the centering ring.
I marked a glue application dowel for a internal ring of glue inside the BT-55 tube. The dowel was set beside the shroud assembly and marked with a pencil for a glue depth mark.
The BT-55 tube is slid down and over the lower centering ring.
A glue fillet is then applied around the base of the tube/centering ring joint.
Three internal support balsa triangles are glued on the centering ring cut and pencil marks on the tube.
Glue was applied, then the excess removed and smoothed with a Q-tip.
Note the small line of glue around the outside edge on the right side picture.
