Biplane Rigging and Assembly
Hardware Notes

Instrument Body Assembly
Sample Faces
Make instrument bodies from
rolled strips of aluminum lithoplate
or strips of manila folder paper.
Paint the inside flat black to finish.
Brass or aluminum tube sections
can be substituted for the lithoplate
however the edges of the laser cut
parts will need to be sanded to reduce
the diameter slightly. Use bent wire
or pins painted white to simulate the
dial indicators.
Assemble with white glue only CA will
fog the plastic.

Note: Hex bolts are the best for a
scale appearance, but a cap head
or hex head bolt are easier to
adjust cable tension.

Capped Rib Preparation:
Lay out the ribs after an initial sanding in a
similar arrangement as shown. Attach the
vertical webbing one side at a time.
( shown in the diagram is a typical
arrangement, refer to appropriate
scale documentation for your model on
specific locations) Trim the ends of the
webs and turn the rib over, apply the
webbing to the other side. Attach the top
and bottoms caps after trimming to length.
Make sure you take in to account the
attachment of the leading and trailing edges,
leaving an overhang if necessary. Sand the sides
prior to assembling if necessary.
Note: depending on the width of the finished
rib cap you may need to raise the rib slightly
to center oversized cap strips.

Rib Webbing Positions (Typical)
To take advantage of the wire trailing edge giving your model
a true scallop begin covering the model from the underside of
the rear of the wing. Attach the fabric as shown going around
the leading edge and back to the rear. Overlap and attach the
material to itself on the underside

Hinge hardware is pre-fitted before covering when the cabling
and linkages are set up and adjusted. Hardware brackets are
attanhed on top of the covering.
Note:
The wood trailing edge was initially used in the prototype 1/3
scale model and later replaced with the wire
NOTE 1:
Wing trailing edge was made from cable in the original
aircraft. For purposes of strength in flying models we used
music wire . When the covering is applied (from the back)
the material will pull the wire in slightly, giving a true scallop.
Attach the wire to the ribs as shown in the illustration by
soldering to the metal brackets as shown. Pin the brackets to
secure in place. Additional wood supports are included for
the trailing edge for flying models.

NOTE 2:
Mount the spruce block to the aluminum tube
after routing the block to fit one half of the radius
of the tube. Install the two keepers and pin in place
to the block. Bond the entire assembly in place.
Mount the hinge bracket by wrapping around the
aluminum leading edge of the aileron. Secure the
hinge to the hardwood stringer by pinning in place. Drill
the wood using a pin drill first, DO NOT force the pin
through the wood. The pin should pass easily
though the hole and be bonded in place. Secure the
front edge of the hinge bracket with a nut, bolt, and
washers. Cut an aluminum tube standoff/spacer to
prevent the hinge from over compressing when the bolt is
tightened.
