Estes Sasha Build #7271, Part 6, Booster Engine Mount Gluing

Test the fit of the nozzle and coupler in the body tubes.

TIP: I usually sand an angle on the lip for easier insertion. With this small taper the inside of the body tube won't turn under.

The shoulder of the nozzle sets the depth of the lower centering ring.
In the picture on the right the tube is upside down, the fin slots should be at the bottom!

Slide in the engine mount and press in place against the nozzle shoulder. No glue now, this is a dry fit. From the top, mark the inside of the tube where the centering ring touches the body tube.

Use the marking guide, center the engine hook line between two fins.

Mark a dowel using the pencil mark on the inside of the tube.
Apply a line of glue around the dowel end an apply a bead of glue around the pencil line inside.

Slide the engine mount in, press the nozzle in the rear until the shoulder lip butts up against the tube end.

Turn the mount so the engine hook is centered between two fins
