HOT-WIRING
INTRODUCTION
.....
In this section, you will hot-wire the foam cores for the wing,
canard, rudder, vertical fin, ailerons, and elevators.
.....
Begin by reviewing the COMPOSITE MATERIALS EDUCATION chapter. That
means more than just glancing through the chapter; study it thoroughly
until you can recite it in your sleep.
.....
Hot-Wiring is not difficult, but will require two people and a
precise, careful approach to obtain good quality cores.
.....
Before we continue, let's emphasize a few important points that you
have already read in the COMPOSITE MATERIALS EDUCATION chapter:
1.
Always hot-wire cut from the leading edge back to
the trailing edge to minimize wire lag; always go
slowly around the leading edge of any airfoil.
2.
Pause at any notches in the templates to let any
wire lag catch up.
3.
Retain all scraps; they may be used later.
4.
All foam blocks must be weighted down carefully;
all template level lines must be re-checked just
prior to hot-wiring.
5.
Hot-wire cores at the top of each block first, to
make weighting the cores down easier.
6.
Any part of the template projecting aft of the
"eventual trim lines" may extend beyond the edge
of the foam block; many template locations are
critical, so strive to minimize wasted foam it
will all be used later.
7.
Mark level lines on each foam core with a felt
tipped marker.
8.
Smile! This is one of the funniest jobs in the
whole aircraft.
MAIN WING CORES
.....
Find the two 10" x 24" X 96" nominal dimension blocks of
polystyrene foam.
.....
Using straight edged trim templates, square up three sides of one
block to generate a core 50.0" long. The fourth edge (along the 50" side
- see sketch) can remain scalloped. The sketch shows the positioning of
the appropriate templates on each end of the block. Note that the sketch
end views are oriented to duplicate the "picture
”
one sees looking at
each end of the block.
