Sail Attachment Points Modification
If the supplied PVC sail reinforcements have not been installed yet, do not use them; the pressure-sensitive adhesive will fail in a short
time. An improved method that has weathered many hours of heavy winds employs iron-on fabric reinforcements with crimped brass eyelets.
If the supplied PVC has already been installed, carefully peel it off (careful around the colored areas).
New reinforcements are made by bonding a double-sided, heat sensitive strip first to a piece of ribbon,
and then to the sail (both sides of the sail). 12 sets of triangular reinforcements must be fabricated as follows:
You should now have 24 triangles with adhesive bonded to one side. Following the manufacturer's instructions, remove the paper backing from
the adhesive and iron a triangle on one side of each sail where the PVC reinforcements used to be located. Align the long edge of the triangle
with the edge of the sail (see drawing below). Orient the triangles at the sail corners for maximum coverage (1-1/4" long piece used at the
top of the jib). Be careful not to dwell too long on the sail and reinforcement with the iron to avoid possibly melting the sail, but do dwell
long enough to get a complete seal. A little experimentation might be in order.
- Cut one 12" long piece of 7/8" wide Heat-n-Bond iron-on adhesive (by Therm O Web).
- Cut one 12" long by 7/8" wide acetate ribbon (by Offray).
- Following the manufacturer's instructions, iron the tape on to one side of the ribbon (try to keep the backing paper intact on the second
- Measure and cut the tape/ribbon into eleven 7/8" squares, and one 7/8" by 1-1/4" rectangle. The longer piece is used at the top of the
- Cut the twelve pieces diagonally to create 24 triangles.
Now, turn the sails over and iron triangles onto
the other side directly opposite of the other triangles. Be sure to press hard to assure that complete adhesion. Trim the overhang from the
sail corners as necessary.
Measure in 1/4" from the sail edges and at the center of the length of the triangles, and make a small "x"
with a pencil. This is where the 3/16" eyelets will go.
Although which side of the sail the eyelet is installed
from does not matter, I chose to have the finished (manufactured) flange of the eyelets on the colored side of the sails. Place an eyelet on
the eyelet tool with the small diameter facing up. The tool and eyelet will automatically punch the correct size hole in the sail. Align the
eyelet tool center with the pencil marks made earlier and carefully squeeze the tool until the eyelet is fully swaged in place. Be careful
not to squeeze so hard that the newly formed flange on the back side punches through the sail to the front side.
Rather than running the sail rings through the eyelets of the mainsail to attach to the mast, cut
short pieces of rigging string and tie loops through the eyelets. The sail rings are then passed through the rigging string loops. This configuration
allows much more freedom of movement around the mast.
A pair of small needle-nosed pliers can be used to reform the boom springs as
necessary to capture the eyelets. Attachment of the jib is similar; however, if the forestay modification will be performed, attachment of
the jib will be delayed until the new forestay configuration is complete.
Even during the busiest times of my life I have endeavored to maintain
some form of model building activity. This site has been created to help me chronicle my journey
through a lifelong involvement in model aviation, which
all began in Mayo, MD. There
is a lot of good information and there are lot
of pictures throughout the website that you will probably find useful, and might
even bring back some old memories from your own days of yore. The website began life around
1996 as an EarthLink screen name of ModelAirplanes, and quickly grew to where more server
