Estes Space Ship One, Kit # 2191, Build Part 4, Engine Mount Gluing & Jig

I did add a Kevlar Shock Cord tied under the upper centering ring.

I glued the mount into the tail cone using Fabri-Tac glue.

From the top - 

A Fabri-Tac glue fillet was applied and smoothed out using a Q-tip.

Here's the assembled wing jig.

You will need it in the next step to glue the wings onto the body tube.
