The BT-20 engine mount tube has to fit inside. The nose cone tip is removed.
Set the engine mount tube over the NC tip and trace around it with a pencil.
Saw off the end on the pencil line.
More of the nose cone lip had to be removed until the BT-20 tube was a friction fit.

The top of the shoulder is cut off.
Leave a rolled lip on the shoulder so the centering rings have something to glue onto.
