Tri-Fold Shock Cord Mounts, Part 1

Here's how I remember shock cord mounts in the first kits I built:
Cut two slits, collapse the middle, insert the shock cord and glue shut.
How did we ever insert the cord from the top and through the bottom slit first? Check the illustration at the right. It wasn't easy.

This illustration is from the X-Ray kit # K-25

The early BT-55 V-2 kit saw a transitional mount, a square of gauze glued over the knotted shock cord.
The gauze was an improvement, you didn't see unsightly cuts in the body tube.

Things changed in the 1967 Estes catalog.

The Estes Alpha introduced the Tri-Fold Shock Cord Mount and the Quick change engine hook.

That tri-fold should be glued a little farther back inside the tube - it's too close to the nose cone shoulder!
