The next step was to glue the centering ring into place.<\/p>\n

Decisions<\/h2>\n

I decided to use 30min Epoxy glue from AusRocketry. I didn’t want to go for 5 minute and I didn’t want to for 24 hour.<\/p>\n

Preparation<\/h2>\n

While every effort was made to ensure glue\/mess did not make its way on o the surfaces where the Centering Ring is to be glued, some does make its way and so I had to clean it off. There wasn’t much. I used some Methylated spirits to clean the surfaces as well.<\/p>\n

Next I wanted to tape up the motor mount exterior, so I would not get any epoxy glue. I also taped up the exterior of the airframe, just to help reduce chance of getting Epoxy on there.<\/p>\n

I also decided to stuff some paper up the Motor Mount tube to ensure nothing got up there.<\/p>\n

Insert centering ring in ~6mm and mark on the motor mount three places with pencil. This helps us know how far we have to push it in.<\/p>\n

Gluing the Centering Ring<\/h2>\n

This was a carefully thought out job.<\/p>\n

    \n
  1. Internal and External ring is sanded with Grit 60<\/li>\n
  2. Sand internal\/external with Grit 60 sand paper<\/li>\n
  3. Mix the epoxy resin and hardener<\/li>\n
  4. Apply some of epoxy to the external surface of the centering ring. Need to be liberal in application, but not so much it drips too much or make a mess.AS YOU DO THE JOB, rotate the rocket so the glue doesn’t drip down to one area of the rocket!<\/li>\n<\/ol>\n
      \n
    1. Apply liberal amount of epoxy on inside of air-frame (a ring)<\/li>\n
    2. Apply liberal amount of epoxy on outside of the motor mount (a ring)<\/li>\n<\/ol>\n

      Remember, keep rotating the rocket.<\/p>\n

        \n
      1. Slide the centering ring on<\/li>\n
      2. Double check the depth the centering ring has been push in<\/li>\n
      3. Remove the wire holding the centering Ring<\/li>\n
      4. Take the rocket out of the Jig and attach to pole and cable-tie up<\/li>\n<\/ol>\n

        Here are some pictures.<\/p>\n

        Never used the Syringe in the end. Used chopstick instead.<\/p>\n

        After this I slid the Centering Ring on. This requires two hands, so no photos.<\/p>\n

        Then I erected the rocket against the workbench, so that Gravity would bring the Epoxy on to the top of the Centering Ring.<\/p>\n
