Estes Mini Bomarc Clone, Kit #TK-5, Part 3, Engine Mount



The original kit instructions don't mention it - 
I did have to cut a relief notch for the engine hook. Here I've marked it with pencil.

The burrs inside the rings needed some light layer peeling to fit over the BT-5 engine mount tube.







I don't like using a tri-fold mount in smaller diameter tubes so I laced some Kevlar below the upper ring. After pulling tight, a glue fillet will lock it in place.



The lower ring slides up to 1" from the bottom of the BT-5 tube.

The upper ring is even with the top of the tube.



There wasn't an engine block in the original kit. I added one.

Slide in place against the upper bend of the engine hook, then add a glue fillet and smooth with a Q-tip.





Also added was the new heat shrink tubing slid over the first four inches of the Kevlar line.
This is butted up against the top of the centering ring and hit with a heat gun.

After heating, the shrink tube ends up tight around the Kevlar line.
