Estes Black Brant XII, Kit # 9723 Build, Part 16, Gluing Up The Engine Mount

The centering rings were loose on the 29mm engine mount tube. I built up the inside edge of the ring with a small bead of wood glue. Let it dry.

Check the fit. If it ends up too tight, you can sand the glue edge with 400 grit.

The black retainer ring was also loose. I wrapped some masking tape around the tube to hold it in while the low plastic fin can was slid in place.

When all is glued up, the black retainer ring is even with the bottom of the white plastic fin can.

Fillets were applied using a drop of glue on the end of a Q-tip.

Tubing, cardstock rings and balsa fins are glued on with wood glue.

Plastic parts are glued onto everything else with two part epoxy.
