H. Building Board
A soft, but stiff board such as acoustic
ceiling tile or insulation wallboard to
easily take straight pins for holding parts
during assembly. This soft board should
be nailed or glued to a hard board so it
will be flat. You can use a table, but a
portable board is good for turning it
around to make the work easier.
Build the wings, fin and rudder, stabi-
lizer and elevator directly on Plan D02.
Place the plan on your building board
and cover the plan with waxed paper or
plastic wrap. Be careful applying glue,
especially super glue. Although the
waxed paper or plastic wrap protects the
plan somewhat, you could accidentally
glue the protective sheet to the model
parts, or even to the plan itself.
An alternative, if you have a dedicated
modeling area, is to lay a sheet of glass
over the full-size plan sheet and build
directly on the glass, using tape and
weights to hold the parts in position. If
you use this method, watch out for sharp
edges on the glass.

board. This will prevent your gluing the
formed part to the work board. The part
will end up glued to the paper, but this eas-
ily sands off during the final finishing.
Some people prefer to use waxed paper to
prevent the part’s sticking, but if you use
heat against the jig, you will melt some of
the wax into the laminated part.
Begin by soaking the wood in cold water
for 5 or 10 minutes, then pat it dry. Start-
ing at one end of the jig, pin the first strip
tightly against the jig, applying heat when
needed, then move along bending and pin-
ning the wood to shape as you go. Cut off
the excess strip at the end of the run.
Go back to the end where you started and
brush on a thin coat of white glue or car-
penter’s glue and apply the second strip of
wood, pulling and replacing pins as you
go. Applying heat at this point will make
an almost instant bond between the wood
strips. Proceed in this manner until you
have built up five wood strips and then
allow the part to dry thoroughly, after
which the formed shape will be permanent.
Carefully remove the part from its jig
and sand off the excess glue and paper.
The final step is to sand the correct profile
as required by the instructions and full-size
plans.
With one exception, your NIEUPORT
28 model need not be painted or finished
at all. However, it is recommended that
you seal the wood parts and Britannia
castings for protection. Due to the intri-
cacy of the finished model, this is best
done as you go. My personal preference
is to use 3-pound cut shellac, thinned
50% with denatured alcohol. This dries
fast, so you can keep working, and a sec-
ond coat can be applied if you want more
shine.
A light tan stain on all wooden parts
will help to make the entire structure uni-
form in color. However, glue spots on the
wood will resist staining, and any end
grain will stain darker than the rest. To
achieve an even application of stain,
carefully scrape off any excess glue, then
seal the wood - especially the end grain -
with thinned shellac. After this is dry, a
light application of stain, using a soft
artist’s brush, should give an even finish.

Before commencing each stage of con-
struction, have all the parts for that stage
identified and ready to use. It helps to lay
each part on its corresponding location on
the full-size plan to facilitate identification
as you proceed. Lightly sand wood parts as
required to remove any fuzziness and pre-
pare the castings parts as noted above.
To achieve maximum accuracy in your
model you must fabricate bent laminated
parts for wing tips and the empennage. The
flexibility of the supplied Tanganyika
wood strips - especially when wet - makes
this relatively easy. The necessary jigs are
included in the kit. Because some of the
curves are relatively tight, you may need to
apply heat to the wood as you wrap it
around a jig. This may be done with the
angled tip of a 20-30 watt soldering iron.
Firmly affix each jig, to a work board with
a sheet of ordinary typing paper or news-
paper sandwiched between the jig and the
When dry, another application of shellac
or your favorite varnish will complete
the process.
Britannia castings parts may be left
polished or painted a steel or gunmetal
color. Other fittings, such as turnbuckles,
can be painted black or dark gray.
Varying the tones on the various parts
will add a nice contrast to the finished
model.
The distinctive woven plywood “peach
basket” seat back is provided as a
Britannia casting to simplify construc-
tion. You will need to paint this, after
gluing it to the seat, to give it an appro-
priate wood finish. First paint the seat
back with a very light tan. When this is
thoroughly dry, dry-brush a light golden
brown, allowing much of the tan to show
through, then finish off with a russet
brown wash to accentuate the pattern. A
light coat of varnish will then give you
the desired wood effect.
After you have shaped and finish sand-
ed the laminated basswood propeller, you
can achieve a more authentic look by
staining it golden mahogany and then
building up two or three thinned layers
of varnish or shellac.
Sand all wood surfaces with 400-grit
dry sandpaper and thoroughly wipe off
all dust. A tack rag would be helpful.

The Gnome-Rhone Monosoupape Type
9N rotary engine is essentially indepen-
dent of the rest of the aircraft. It slips
onto a fixed crankshaft around which the
engine rotates. Super glue and/or epoxy
should be used to assemble the parts.
Care must be exercised with the many
small parts. Refer to Figures 1/1 through
1/13. For clarity, drawings may show a
single cylinder. It is a simple matter to
repeat the assembly for the other eight
cylinders. The actual assembly of the
engine is pretty straightforward. The key
to success is to carefully clean up all of
the castings and then to dry fit every-
thing before applying glue.
