Pack 4 - Stage 18. Another hull section and the first class stairwell dome.

[Mark, The Master Modeller]

Stage 18 gives us the stairwell dome and another section of hull.

Let's start with the stairwell dome.  Put the dome in position on the superstructure.  Don't glue anything yet. 

The skylight is placed over the dome.  Again, don't glue it yet.

Hold the skylight in place with some masking tape to keep the parts safe.

Put the hull section in position and secure it to the lower hull with three screws.

Screw it to the connector plate with two Allen headed screws which were supplied in stage 15.

Finally screw the bulwark to the top of the hull section.

This completes the stage.
