Construction Manual
n
Step 82 - Fuse Assembly (Wing saddle)
Place both side frame assemblies
with the plywood sides on the
buildilng surface - the framing
sides up.
In the wing saddle area use more
of the leftover 3/16" sq. balsa to
cut the two small uprights and the
long horizontal piece to frame
out the saddle.
Make good clean cuts and glue all these pieces in place - again on
the framing side of the sides. Also make sure that the horizontal
piece is straight along the cut edge of the plywood FS1.
n
Step 83 - Fuse Assembly (Wing saddle)
Once the glue has cured from the previous
step, cut away the top portion of 3/16"
sq. basswood that is spanning the wing
saddle's opening. Do this for both the port
and starboard frames. Sand these cut edges
smooth to match the plywood.
n
Prepare your work area (plans - top view)
Now tape the fuselage top-view plan
and a fresh piece of waxed paper on
your building board.
Note that as we've shown here, it's
best to allow the back portion of
the plans (where the "break" in the
bottom formers is) to fall off the end
of your building board - the fuselage
side frames won't sit flat because of this break.
n
Step 84 - Fuse Assembly (plans - top view)
Locate FB from LP5. This is the bottom
of the forward fuselage. If it does have
a bow in it, allow the bow (concave
side) to face up as you pin it in position
around it's perimeter, as shown here.
Now you'll attach the left fuselage
framing to FB. Working and gluing a little bit at a time, make that
the framing runs true along the length of FB.
Also use the triangles we provided (noted way, way, way back at the
beginning of this manual), as they will help you guarantee that the
framing is held exactly perpendicular (90°) to FB.
n
Step 85 - Fuse Assembly (F2)
Locate F2 from LP4. This is glued in place,
locking in just forward of the doubled-up
framing as shown here.
n
Step 86 - Fuse Assembly (LG1. LG2)
Locate LG1 from LP1 and both LG2s from
LP1 and LP2. They all have an etched
circle designating the side which should
face forward. Glue one LG2 on top of the
other, then glue that sub-assembly onto the
fuselage floor (FB) - centered up under the
holes for LG1 as shown here.
Then glue LG1 on top of the LG2s, making sure it's aligned
properly when by fully inserting both tabs into the pre-cut holes
on the fuselage side.
n
Step 87 - Fuse Assembly (WH1, WH2, WH3, WH4)
Locate WH1, both WH2s and WH3
from LP3. Also locate both WH4s from
LP2.
These all have the circles etched
which designate what?
Yup, the front edges - so listen up - here's what we're gonna do.
First you're gonna make an WH1 sandwich with WH2 bread. Get it?
Make sure the pieces are centered up with each other as the glue
sets, then make another sandwich with WH3 in the center and
WH4 for the bread.
Hold the mayo on both. I'm a mustard man myself.
n
Step 88 - Fuse Assembly (WH1, WH3 sandwiches)
Now its time to glue these two
sandwich assemblies into the
fuselage as shown here.
The WH1 group goes toward the
front, with the WH3 group just
behind.
Make sure they are in the correct orientation by using the.... the....
come'on, you know this one. The.....etched circle, that's right. Also
make sure they are each pushed fully into the fuselage side sheeting.
Note that the tabs will extend past the outer edge of the side
sheeting, so when sanding later it will give a better looking finish.
n
Step 89 - Fuselage Assembly (starboard side)
Locate the starboard fuselage
side as it's time to glue it to the
fuselage assembly.
For the most part, this will be
held perpendicular without the
use of the triangles, but have
those nearby, just in case you
need them.
Dry fit this first as there's a lot of things to get right. The side should
be resting on top of the bottom sheeting, then the tabs for the
LG1, WH1, and WH3 should be fully inserted into the pre-cut holes
in the side sheeting Also F2 needs to be in place, up against the
uprights.
When you're satisfied how this goes together, remove it apply glue,
then carefully glue this side piece in place. Make sure everything
stays aligned and the side is straight along the entire length of the
bottom sheeting.
n
Step 90 - Fuse Assembly (cross bracing)
Locate one of the 3/16" sq.
basswood pieces you cut away from
the wing saddle areas. Measure, cut
and glue in two cross braces for the
front of the fuselage.
One will go across the bottom, glued
to the sheeting and side framing.
The other will spanning the distance
between top of the fuselage sides.
Make sure the fuselage sides are parallel in when doing this.
