I use Corning Formular foam for the production of Compulsion/Addiction and
other custom wings. I do this because the Corning foam cuts much better and
is crisper at any given weight than its Dow equivalent. Unfortunately,
Corning foam isn't readily available in California so I have to import it
from either Arizona or Oregon and the transportation cost is almost as much
as the foam. However, by buying in large lots (more than 100 sheets), I'm
able to get the cost down to where it's comparable with the equivalent Dow
foam. I currently have available more Formular 600 and Formular 150 foam
than I'm going to need during my limited remaining time in production.
Consequently, I'm willing to sell some of this foam to bagging enthusiasts.
I have available many 4'X8'X3" sheets of both 600 and 150 foam. These
sheets were shipped palletized and shrink wrapped in an enclosed truck, so
they're in excellent condition with no gouges or damaged edges. The
advantage of using three inch thick foam for unlimited TD wings is that a
pair of wing cores can be cut from a single three inch piece of foam blanked
out to the proper size. This ensures that the matching left and right hand
panels are a perfect mirror image and saves the time of having to blank out
two core pieces instead of one.
Specifications of the foam are as follows:
Formular 600: 60 PSI crush resistance in all three axis and a weight of
2.4 pounds per cubic foot. I consider the Corning Formular 600 foam as
superior to Spyder foam as it has its strength in all three axis instead
of only one at very little increase in weight (about three percent). It's
also much less expensive and is the obvious choice for root panels or wings
that are intended for extreme loads (dynamic soaring, etc.).
Formular 150: 15 PSI crush resistance in all three axis and a weight of
1.35 pounds per cubic foot. This foam is the best combination of
acceptable strength with light weight and perfect for eigher HLG wings,
two meter wings or the outer panels of multi panel unlimited wings. It's
even lighter than Dow Gray Board and stronger as well. The only foam that's
lighter is the styrofoam popcorn foam used for coolers which is unacceptable
for vacumn bagging. If used for HLG wings, this three inch thick foam
has the additional advantage of allowing two complete sets of left and
right panels out of a single piece.
I'm not trying to make any money on this foam, so I'm offering it at the
same price I paid. Formular 600 is $30 per three inch sheet and Formular
150 is $24 per three inch sheet. It's too expensive and time consuming to
cut up, package and ship this foam, so it's strictly a cash and carry
offer. I'll be attending the HSS SC2 contest this Sunday in Costa Mesa and
can carry two sheets for delivery at the contest to the first person who
responds. The remainder of the numerous sheets can be picked up at my home
in Poway, CA, or delivered at the TPG SC2 contest in Poway in late
November. If interested, please e-mail to arrange a pickup time.
Thanks for your consideration;
Fred
