Estes Black Brant III, Part 9, Engine Mount and Launch Lug

The fit of the mount was loose in the BT-50.
With a glue stick, one wrap of copy paper was glued around both green rings.

Glue was applied inside the tube using the dowel pencil line from the last step.
The coupler was quickly inserted and pushed in place using the engine mount up to the lower pencil line on the engine mount tube.
The engine mount was removed.

After the coupler glue had dried the mount was glued in.
With the coupler in place you have a "stop". The mount is slid in until it stops against the reinforcement coupler edge.

The Estes instructions have you glue in the nozzle and mask if off for the black paint.
Don't glue it in now, paint it black then glue in place and save yourself some tight masking.

The launch lug is glued in line with the engine hook, 4" above the end of the body tube.
