Stop the gasses from getting there!
|Sometimes, we just need to seal
off the rockets.
It might be to convert a centering ring into a block.
It might be to make a paper transition.
It might even be to give a surface that a rear-eject engine mount can push against.
We've got the bulkheads you need.
Just be sure that you glue them securely in place.
Note that there are no firm standards for couplers, so the bulkheads that fit inside of a coupler might need to be sanded down a bit.
rear-eject rockets, we have special cardstock bulkheads. They come with
a crossover reinforcement, to keep from being deflected by the pressure.
They also have two separate points built in to attach a shock cord. One is in the center, the other near the perimeter. During assembly, simply insert the cord through the provided hole, down around the crossover, and then back through the hole. Then tie the cord and glue it into place.
