Estes Python 4 Build, Part 5, Gluing the Engine Mount



A ring of glue was rolled in the rear tube using a marked dowel.

Apply a ring of glue around the dowel end.
Set the dowel into the tube up to the pencil line on the dowel.
Roll the glue into a bead all the way around the inside of the tube.

The tail cone is used to press the engine mount into place.
You aren't gluing the tail cone in yet. When the tube end is even with the tail cone remove it.



The centering rings were a little loose.
I wanted to let the mount dry with the tube sitting upright.
To make sure the mount didn't slide down a piece of tape held the mount up.



There only glue holding the mount is above the upper ring.

A fillet was applied to the inside and lower ring joint with a Q-tip.


The tail cone was glued in using plastic cement.

The engine hook is centered between two fins and in line with the launch lug.
