48. Remove the elevators from the plan, sand them to the tapered shape and bevel the leading edge.
49.
To make the elevator joiner and control horn, you will need the 3-1/2" (88.9mm) piece of 1/16" (1.5mm) music wire, the
1/16" (1.5mm) I.D. wheel collar, the 4-40 headless set screw, and the 4-40 RC link from the hardware bag.
Mark the exact center of the wire and file a slight flat there. Slide the 1/16" wheel collar onto the wire until the setscrew is
positioned directly over the flat, put a drop of Loctite® thread locker or medium CA in the set screw hole and tighten the
screw tight against the flat.
50.
Put a drop of Loctite® or medium CA on the set screw threads and screw the 4-40 RC link down on the setscrew until it
contacts the wheel collar.
It is important that when the glue sets that the pin in the RC link is parallel to the music wire.
51.
Measure out 1" (25.4mm) from each side of the wheel collar on each side and mark. Bend the wire 90 deg. at each mark
making sure the bends are 90 deg. from the control horn and parallel to each other.
52.
Mark the center of the bottom of the stabilizer at the trailing edge then make a mark 1/8" (3.2mm) either side of the center
mark. Saw 1/8" (3.2mm) deep at each mark and remove the wood in between. This provides clearance for the wheel collar
on the control horn.
53.
To mark where to drill the elevators for
the control horns, pin the elevators to the
stabilizer with the outboard ends about
1/16" (1.5mm) in from the rudders.
Lay the control horn over the elevators
with the collar centered in the notch and
mark where the wires need to enter the
elevators.
54.
Remove the elevators and drill with a 1/16" (1.5 mm) bit where you have marked.
Cut a 1/16" wide and 1/16" (1.5 x 1.5mm) deep groove from the drilled hole to the
inside end of the elevator. Trial-fit the elevator horn into the elevators and make
any adjustments needed to get the wire to lay flush with the elevator leading edge
and the elevator leading edge to match the stabilizer trailing edge.
55.
Place pieces of wax paper on the stabilizer where the horn will contact it. Use 5-
minute epoxy or thick CA to glue the horn into the elevators and then pin up
against the stab to hold everything in alignment while the glue sets.
56.
On a piece of wax paper glue the RUTs to the top of the RUs then sand smooth and round the edges. Smooth and round
the VSs also and layout the lines where they will glue onto the ends of the stabilizer.
Drill and slot to match the rudder pushrod exits in the end ribs.
