Estes Blue Origin New Shepard Build, Part 2, Engine Mount

The rings were very tight so I widened the inside diameter with some sandpaper.

This could have been a pre-production kit - there was an engine hook relief slot in one of the 20/60 centering rings. There is no engine hook on this mount.

The instructions don't mention it, but I set the upper ring a bit lower than the illustration showed. This allows a slightly larger glue fillet on both sides of the ring.

Don't apply a ring of glue for the lower ring. Press the ring up the tube (no glue yet) using the tail cone and inner retainer ring. 

If you are new to the retainer rings, there is an inside ridge that will stop the slide against the end of the BT-20 tube. Keep sliding up until you hit the ridge.   

Remove the retainer ring and tail cone.

While the instructions said to apply a ring of glue 1" from the rear, My lower ring spacing was a bit longer than 1". 

With the ring in position, now apply a glue fillet on each side of the lower ring.

An engine block is glued in even with the top of the engine mount tube.

Here's what the engine mount looks like, pretty simple.

The tail cone and screw retainer ring are not glued in place yet.
