Next step was to glue the Motor retainer on using JB-Weld.
We followed the steps that were on the AeroPak TailCone. The last two in the screenshot below.

We needed to use Acetone to clear the internal threads of the retainer component we wish to epoxy to the Motor mount.


Once clean, we make up a generous amount of JB-Weld and mix thoroughly.


Once done, we add a generous amount of JB-Weld to the motor mount, making sure to keep it to the area that the retainer is going to slide up to.

Then I slid the adapter on. As I slid it on, I turned it around a little, back and forward, in and out to ensure that the JB-Weld Epoxy made good contact.

I removed excess JB-Weld inside and outside using paper towel and Acetone.

I checked all around the rocket to see if there was any stray JB-Weld. I made sure that the adapter was butt up against the Motor Mount.

I left it overnight to dry.
