Semroc USS Andromeda KV-97, Part 5, Low Engine Mount End Assembly

The lowest centering ring is notched for engine hook movement.
TIP: The flat side will be exposed so sand it flat with 220 grit on a sanding block. Sand one side of the (closed) upper ring, it wall also be exposed.
On the left is before, on the right is after sanding. With the flat side of the ring smoother, it will end up looking cleaner when paint is applied.

Slide on the upper ring up to the 4" mark. Glue in place.
TIP: Glue the notched ring even with the tube end. Use a rubber band to hold the open lower ring ends down against the body tube.

Here's what the low end looks like now.

Set the engine hook. Cut a notch at the top for the engine hook bend.
Place a wrap of masking tape to hold the hook in place.
TIP: Paper masking tape can break down over time. I like to use longer lasting electrical tape.

The 4" long ST-9 tube is glued over the rings with the ends of the rings even with the ends of the tube.

This shows the upper tube/shroud assembly. The main body has been shot with primer/filler and was sanded to surface.
