21) Carefully fit the upper section of the gy-
rosphere container to the lower section.
An index tongue in the upper section en-
gages into a corresponding groove in the
lower section.
22) Insert the 4 mm Allen-head screws and
washers in their threads.
23) Tighten the screws in a series of diago-
nal opposites.
24) Insert the funnel into the hole for the
centering pin. Remove plug from the
ventilation hole in the container top. Fill
up the container with supporting fluid
until the fluid level reaches the under-
side of the translucent container top.
25) Take off the protective cap from the
centering pin and rinse the pin thor-
oughly with supporting fluid.
26) Screw in the centering pin and tighten it
firmly by hand. Wipe off any excess fluid
from and around the pin.
27) Draw up some supporting fluid with the
syringe and inject it into the ventilation
hole. Repeat until all remaining air has
exited from the container. Gently tilt the
container, if necessary. Very lightly tap
on the outside of the container to re-
move any air bubbles that may cling to
the inside surfaces.
