Recommended Glues
Sig-Bond (alphatic resin type) glue works best for the majority of the general framework construction. Areas subjected to
unusual strain, or including metal pieces, should be epoxied with Sig Epoxy Glue (slow drying) or Sig Kwik-Set (5-minute)
Epoxy Glue. You will also find that the cyanoacrylate type adhesives (Hot Stuff, Jet, etc.) can be extremely quick and handy for
some applications. Some of the steps in this instruction sequence call out the specific type of glue to use for that particular
assembly. In other areas you can use your own judgement as to which type is best suited to the purpose and your building
schedule.
About The Building Sequence
The quickest and most efficient way to complete a model is to work on several pieces at the same time. While the glue is drying
on one section you can start on or proceed with another part. The numbering sequence used in this book was chosen as the
best way of explaining the building of each major assembly and is not intended to be followed in exact one-two-three fashion. It
may be desirable, for example, to start building the wing or tail while the preliminary parts of the fuselage are drying. It is
suggested that you read the instruction book and study the plan carefully before beginning to build. That will help make it clear
where construction out of the descriptive sequence can be done.
Notes Before Beginning Construction
Any reference to right or left refers to right or left as if you were seated in the cockpit. Building large airplanes requires a large
building board! For this Cub, you will need a board that is at least 18" wide x 72" long. It must be perfectly flat and untwisted. If
you don't have one that big, go to the local lumber yard and purchase a "door core" of at least these dimensions. Door cores are
normally very straight and true (be sure to inspect it before buying), and they are not too expensive.
A piece of thin foam board or celotex-type wallboard makes a handy top surface for your building board, into which pins can be
easily pushed. Don't be afraid to use plenty of pins while building, particularily when gluing planking on the top curve of the wing
or the round top of the nose. Due to their large size, the full-size fuselage and wing plans had to be drawn in two pieces. Cut out
the adjoining pieces and carefully tape them together along the break lines. Wax paper should be used to protect the plans
during building.
Be careful where you use a ball point pen for making marks on the model during construction. If not sanded off, these marks
may bleed through many coats of dope and show on the finished model. Cut all long pieces of balsa first, followed by medium
lengths, before cutting up any full length strips into short pieces. Leave the die-cut parts in the sheets until needed in
construction. Remove pieces from the sheets carefully. If difficulty is encountered, do not force the part from the sheet. Use a
modeling knife to cut it free. A jig saw is best for cutting out the printed balsa parts. Cut just outside the lines, leaving all of the
line on the part. When fitting the piece into the structure, use a sanding block to bring the edges to an exact fit.
