.
e. When satisfied with the fit, take the Upper Strut Fittings off one at a time, apply epoxy, slip the fitting back into the slot,
bolt it back in place, wipe off any excess glue, and then let dry.
125.
When dry, remove the strut assemblies from the airplane. Carve and sand the spruce Wing Struts to finished shape.
126.
Reinforce the ends of the spruce struts with a layer of fiberglass cloth and thin
CA glue. Also, cover the areas near the center of each strut where the jury struts
will go with fiberglass cloth. When dry, sand smooth.
127.
Lay the wing strut assembly on the plan and mark the location for the 2-56 x3/8"
Flat-Head Bolts that hold the bottoms of the brass Jury Struts. Drill a 3/32" dia.
hole through the spruce struts at these locations. Countersink the holes on the
bottom of the struts so that the heads of the bolts will be flush with the spruce.
Then, thread the bolts in place and leave them there.
128a.
Re-attach the wing strut assemblies to the airplane.
b.
Cut two 3-3/8" long pieces of 5/32" od brass tubing for the Jury Strut Spreader.
Note: If you are building the Clipped Wing Cub, the Jury Strut Spreader should be 2-7/8" long.
c.
Flatten both ends of the Jury Strut Spreader as needed to clear the spruce struts (approximately 3/8" on each end as
shown on the plan).
Builder’s Tip: A regular hand pliers works best for flattening and bending the ends of these brass tubes.
d.
Hold the Jury Strut Spreader in place on the wing struts and mark locations of the holes near each end. Drill the holes
with a 3/32" dia. bit.
129a.
Cut two 4-3/4" long pieces of 5/32" od brass tubing for the Front Jury Struts.
Note: If you are building the Clipped Wing Cub, the Front Jury Struts should be 5-5/16" long.
b.
Flatten the ends of the Front Jury Struts and mark the location of the holes. Drill the bottom hole with a 3/32" dia. bit. Drill
the top hole with a 1/8" dia. bit. There are patterns on the plan to use as a guide for bending the Front Jury Struts to
shape. Be sure to make a right and a left!
130a.
Cut two 4-7/8" long pieces of 5/32" od brass tubing for the Rear Jury Struts.
Note: If you are building the Clipped Wing Cub, the Rear Jury Struts should be 5-1/4" long.
b.
Flatten the ends of the Rear Jury Struts and mark the location of the holes. Drill
the bottom hole with a 3/32" dia. bit. Drill the top hole with a 1/8" dia. bit. There
are patterns on the plan to use as a guide for bending the Rear Jury Struts to
shape. Be sure to make a right and a left!
131.
Bolt the all the Jury Strut tubes in place on the Wing Struts. Epoxy together the
lower ends of the Jury Struts and the Spreader where they overlap each other
and the spruce wing struts. Use 2-56 Hex Huts to fasten them to the 2-56 Bolts
that are already in the Wing Struts. Use 4-40 x3/8" Rd.Hd. Bolts to fasten the top
ends of the Jury Struts to the wings.
Main Landing Gear
132.
Locate the formed wires 5/32" Main Landing Gear, 5/32" L.G. Rear Brace, 1/8" Top Shock Strut, and 1/8" Bottom Shock
Strut. Sand all the wires with 220-grit paper, then wipe clean with acetone or paint thinner.
133a.
Place the Main Landing Gear wire in the front grooved landing gear block in the bottom of the fuselage. Place the L.G.
Rear Brace wire in the aft grooved landing gear block. The Main Landing Gear should be perpendicular to the bottom of
the fuselage, while the L.G. Rear Brace should be angled forward to meet it near the axle. You will have to trim the groove
in the rear block slightly to allow the Rear Brace wire to swing forward.
