Estes STM-012 Kitbash to the B32-M Spike, Part 5, Coupler Bulkhead
Apply a good bead of glue to the top edge. Press on the disk and turn to form an even fillet bead on the inside.
After the glue dries trim off the coupler edge with a single edge razor blade. Get it close to the outside diameter of the coupler.
Sand the bulkhead disk even with the sides of the coupler with 220 grit on a block.
Before gluing the coupler into the upper payload tube, tie on a length of shock cord to attach to the nose cone. This additional shock cord will prevent losing your nose cone and gives you something to attach an altimeter to.
