the same way and connect it to the bellcrank.
- Drill a 4 mm ø hole in the spacer block 11.8 and glue it to the
left-hand side bracket.
- Slip the screw 11.9 through the left-hand bracket and fit the
aluminium bush 11.10, the completed bellcrank and the
washer 11.11 on it. Fit the nut 11.12 on the screw and tigh-
ten it fully. Slide the rivet bush 11.13 into place and secure
the bush 11.3 with the screw 11.14.

- Push the tubular rivet 11.18 into the block 11.8 from the out-
side.
- Push the ring-screw right through the assembly.
- Press the rivet nut 11.19 into the hexagon disc 11.20 and
screw it onto the ring-screw.
- Assemble the right-hand bearing bracket and the second
rivet bush, screw and nut. Glue the spacer block to the right-
hand bearing bracket.
- Glue the completed mechanism to the pressure vessel;
check that it is central and aligned with the conning tower
bulkhead 2.13 (F).
- Connect the pushrods 10.9 and 11.7 using the collets 11.21
and grubscrews 11.22. Ensure that the hydroplane is hori-
zontal and the tubular rivet 11.2 vertical before you tighten
the grubscrews.
- Locate the tube 11.23 which forms part of the depth control
mechanism and file the bottom end of it to a wedge shape
on both sides. Cut a slot in the top end of the tube at right-
angles to the bottom wedge. Cut the screen 11.24 to shape,
curve it as shown and glue it in the slot.
- Push this assembly into the tubular rivet 11.2.

- Cut out and drill the guide cone 12.8 over the top, fit and
align it carefully and glue it in place.
- For additional security we recommend that you drill a 1.5
mm Ø cross-hole in the central tube 12.4 in the region of the
solder joints, by the screw 12.7 and the spacer tube 1.7 and
fit a retaining pin through the holes.
- File out the guide bulkhead 12.9 to clear the ever 10.5 as
shown in the sketch.
- Place the complete central screw assembly in the front hull
section. At the same time thread the large guide former 12.9
into place, but do not glue it at this stage. Route the screw
