insert the stern tubes and glue them into place carefully with "UHU acrylit" both from the outside and
inside at the pressure tank and also on the hull with the small wedges made from scrap material.
Keel, Aft Diving Stabiliser
Glue the halves of the keel triangle (10) and of the diving stabilisers (43a, or 32 for the display model)
together. Sand the stabilisers to a point towards the rear and round off the front edge so that the
profile will look like that of the plan. Now glue the keel triangle with ABS adhesive to the link line of the
hull and ensure that the distance to each ship's screw is the same and that the triangle is vertical.
Attach it to the hull with adhesive tape until the adhesive has dried. When gluing the diving stabilisers,
make sure they are adjusted well. For this purpose, look at the hull from the rear and check that the
stabilisers are not only vertical to the keel triangle but also to the line of the whole ship otherwise your
submarine will not dive or go straight on. The stabilisers are glued to the keel triangle with ABS
adhesive. Finally, the braces (25) and depth rudder fins (43, or 31 on the display model) can be glued
to the stern tubes with epoxy adhesive.
Assembly of the Flood Tank
The flood tank is assembled from the floor (53) and upper part (52). Cut out the floor from the
underside. Cut out the support (55) for the ventilation pipe, drill a 5mm hole in it and glue it centrally to
the floor 100mm behind the front recess.
At the same place in the upper part, drill a 5mm hole for the ventilation pipe. Glue the pipe into the
upper shell and holder using epoxy adhesive and simultaneously glue the floor with ABS adhesive into
the upper part. Cut off the edge of the upper part and sand it level with the floor. Drill a 5mm hole each
fore and aft into the front very close to the floor for the connection pipes (56) and glue these into place.
