Estes Black Brant II Kit #1958 Build, Part 4, Engine Mount

The instructions imply that you should glue the low end of the short BT-55 tail cone tube first. You do want to put the bead of glue on the tube so nothing squeezes out when the parts are slid together. I used the Beacon Fabri-Tac glue on the plastic to tube joints.

GOTCHA: You should glue the top of the tail cone tube first. If you glued the bottom of the tube you won't be able to get glue inside the top edge. The blue tube would be in the way!

Two 50/55 centering rings are glued on top of the plastic coupler.

The first ring was slid on the top. I set down a bead of glue then slid down the ring. As the ring was slid down it was turned to spread out the glue.

The second ring is glued and stacked on the first one.
Notice the blue tube is extended out the top. The instructions show it even with the top of the upper ring.

The yellow spacer tube is marked 1/2" from the low end.
The engine block is slid in from the top. My engine block was very loose, I had to build up the sides with a bead of glue.

With the yellow tube slid in up to the pencil mark, the engine block is slid from the top until is rests on the yellow tube. Then a glue fillet was set in from the top.
