Estes Equinox Build Part 5, Engine Hook Retention

The marking guide didn't make it around the body tube!
It's not really needed anyway. The launch lug is glued directly opposite the engine hook. The jet tubes glue beside the lug.
The wing assembly glues over the tube ad onto the jet tubes.
You can pretty much do this by eye without marking the tube.

A Mylar lock ring is provided to go over the engine hook.
I've never liked Mylar rings over the outside of a minimum diameter model. After that ring is glued over the engine hook, you are supposed to glue two jet tubes, a launch lug and upper fin assembly over the raised Mylar ring! Nothing will sit flat against the body tube with the ring in the way.

I decided to use a rectangle of 110 lb. card stock instead.
I drew what I though was the right size on the body tube. The rectangle hold down piece ended up being larger at 1 1/8" x 2".
Cut to this size it won't interfere with any fin or tubes glued to the body tube.

A thin coat of white glue was applied to the back and the card stock piece was smoothed out with my Sharpie burnisher.
