Centuri Skylab Build, #KB-4, Part 12, Kevlar & Engine Mount Gluing



If your Kevlar starts to fray or unravel, a drop of glue will hold the end tight for tying.

Tie a small loop knot. I added a heat shrink tube like in the New Way kits.   


My loop knot was almost too big, Keep it small so the bare Kevlar won't be exposed to the ejection charge.

The loop was passed under the upper bend of the engine hook. Carl at Semroc came up with this idea.


The 3D nozzle bell was slid up until the low bend of the hook was even with the end lip of the nozzle.
 
A line of wood glue was rolled around the outside of the tube. The centering ring was pressed in place. 
A Fabri-Tac fillet was added around the outside of the card to plastic  ring joint.
