Estes Nike Smoke #7247 Build, Part 9, 18mm Engine Mount
The lower centering ring is recessed inside the body tube.
I can go ahead and give the inside edge a coat of CA glue. The glue fillet around the lower ring will be above the CA glue ring.
TIP: When you mark the engine mount tube for the centering rings and engine hook slit, mark the tube in more than one location.
If all marks are in the same line, your centering ring marks will be covered by the engine hook.
I punched a small recess in the upper ring where the engine hook will sit.
The inset picture shows the lower centering ring and hook recess.
This mount got the replaceable Kevlar treatment. Black electrical tape holds the Q-tip guide tube in place.
