Estes Hornet Build Part 2, Engine Mount

Set the centering rings in place and pencil mark the rings directly opposite the engine hook.
These rings are fairly thin and fitting the tube will be tight.
A round hole was filed in both the rings to fit the plastic (Kevlar) tube.

Cut the low end Kevlar tail even with the end of the engine tube.
You want a tail to grab onto when the Kevlar is pulled for checking it's condition or replacement.

Note the upper end of the plastic straw is not all the way to the front end of the engine mount tube. I try to keep the end a bit away from the ejection charge heat. The red plastic guide tube extends a little past the centering rings on both sides.

The inset picture shows the finished 24mm engine mount. The engine hooks are hanging over the back end of the mount.

I'm not showing the build of the 18mm engine mount, no need as everybody knows how to make one.
I did end up using the supplied blue engine mount tube. This blue tube seemed to be stronger with a shinier outside surface than what I'd seen in the past.
