Here's a tip I picked up on the Sirius Interrogator build:
Set and tie the Kevlar length before gluing in the engine mount.
Lay the mount next to the body tube, allowing for the engine mount tube being flush or extending a bit out the back.
Fold over the Kevlar below the top edge of the body tube.
Tie the loop for the elastic shock cord attachment.
Unfortunately, the centering rings were small! the entire mount just slid right through the tube. I wanted a tighter fit.
I'll have to build up the inside diameter of the main air frame tube.
This method is best suited for LPR rockets.
A single piece of 24 lb. copy paper should do the trick.
Roll and set in the tube and mark the overlap.
Cut to size.
This is where a glue stick comes in handy.
Glue sticks allow for re-positioning. You'll probably have to try this twice to get it right.
Try for a good even coverage over the entire piece of paper.
Roll the piece and set in the tube. Allow the edge to overhang the end of the tube by about 1/8".
The ends of the roll will probably stick to each other.
In the next post the paper will be rolled into place from the center (bottom right corner) to the edges.
