- Fig. 5 shows an overview of the die-cut parts. Break out the
components and clean up the cut edges. Don't throw away
the ring 3.2; it is needed later.
- Assemble the parts 1.1 - 1.4 to form the equipment frame-
work, check alignment and glue the joints.
- Glue the mast base 1.5 to the base plate 1.6 - Fig. 6.
- Slide the mast plate 1.6 into the bulkhead 1.2, but do not glue
it - Figs. 7 and 8.
- Drill 3.5 mm Ø holes in the hull reinforcements 1.7 and 1.8,
press the rivet nuts 1.9 in the holes and glue them - Fig. 9.
