METHOD #2:
Fabricate a drill bushing from a tube with 3/8” O.D. and an
I.D. to fit a long drill bit you have (a long #11 or 1/4” bit will
work well). The bushing should fit tight in the “T”-Bone and
extend long enough out of it to allow pulling it out. RANS
uses a steel bushing with a welded on handle. Lubricate the
bushing for ease of removal and insert through the front of
the Leading Edge Spar and the “T”-Bone until bottomed
against the inside of the Leading Edge Spar. Drill through
the Leading Edge Spar with the long drill bit using the drill
bushing as a guide. After drilling pull the drill bushing out
about 1/5” and drill through the AFT end of the Spar to a size
short of 3/8”. Remove the drill bushing completely and blow
out the interior of the “T”-Bone. Holding the Wing steady,
insert a 3/8” drill bit through the FWD end and drill out the
AFT wall of the Spar to 3/8”.
CAUTION: It is very important,
to hold the wing completely stationary while drilling the AFT
hole. Otherwise, hole elongation will result.
Preferably use a
bit with a short cutting area (reduces the danger of
elongation in the front hole).
14.
Insert Leading Edge Spar Attachment Bolt and tighten. Tighten bolt
enough to take out play
15.
Connect the upper end of the Aft Lift Strut to the Lift Strut Plate at the
Trailing Edge Spar.
16.
Temporarily install the Rod End in the lower end of the AFT Lift Strut
between the Gusset Plates on the FWD Lift Strut. Pin only at this time
using the bolt. Do
NOT
forget to insert the bushing in the Rod End.
NOTE:
The Rod End on the lower end of the AFT Lift Strut is used to set the Wing
washout during rigging.
Refer to
RIGGING
for information.
NOTE: Both
wings must be installed to the Fuselage before washout is set
.
17.
After washout is set, tighten and check all Strut connections.
18.
Apply desired surface finish to Jury Struts and install.
19.
Support Lift Struts with a block of wood or similar material about halfway
down to straighten them. The weight of the Wing causes a slight bend.
Look down the Strut to get a good idea if the struts are straight.
20.
Bolt the Jury Strut Assembly in place as shown in the parts manual.
Should you not be able to achieve proper fit, then it is possible to space
the eyebolts up with washers. You can also use washers at the drilled
head bolt locations if needed. Use Loctite and safety wire the drilled head
bolts in place. Tighten all attachment bolts and nuts.
