Fit the hinge pin guides
These guides are the 2 lengths of aluminium tube on the Card that are used to guide the hinge
pins through the door jambs and into the cowl hinges. When the cowls are finally installed the
ends of the hinge pins will be bent in at right angles and the door will hold them in place.
Refit the bottom cowl to the fuselage and hold the hinge in against the joggle then mark a line
beside the firewall and directly behind the hinge. Drop the cowl and drill a ¼” hole at this
point as shown above left: it will be just inside of the fuselage skin.
Mark a point on the front of the door jamb 10mm in and in line with the cowl join as shown
above right, which will be very near to the waterline, and drill a ¼” hole towards the hole that
you have just drilled. Use a file to round the ends of the guide tubes slightly.
Continue to drill through the rib until the guide tube can be pushed all the way from the door
jamb and through the firewall.
Allow the guide tube to protrude very slightly,
about ¼” as shown circled at right.
Check that the hinge pin will line up with the
bottom cowl in place and then fix the guide tubes
in place with 5-minute Araldite and flock.
Hint : a strip of masking tape under the tube acts as
a dam to keep the Araldite/flock mix in place
while it cures. Once the Araldite/flock mix has
cured use a hacksaw to cut the tube off flush with
the door jamb.
Clean any burrs and flock out of the guide tube.
Repeat the process for the other side of the fuselage.
