Materials list: 3 yards of 41" ¾ ounce ripstop nylon. (1/2 yard per panel) Five 48-inch pieces of 1/8" pultruded Fiberglass rod. (or 1/8" carbon rod) Five 1/8" i.d. ferrules. 71 feet of 50 pound dacron line. 30 pennies. Nylon scraps to make penny weights. Why a 20 foot Circoflex? It makes the best use of the cheapest (
straight stitch ½” in
from the edge. Fold down flap and top stitch it. Fold all seams in the same
direction. Sew all 6 panels together, making one long panel 18" wide and
20 feet, 1 inch long. On the
(finished) side, draw lines for the sleeves 1" in from both edges and the
entire length of the panel. Crease along these lines. After the lines are
marked and creased, sew the ends of the panel together, the same as all the others.
Open out the folded sleeves, do not sew them closed. After the ends are joined,
fold on the line, and sew the sleeves closed. The front sleeve for the sticks
should have a 2” part left un-sewn at 6
o’clock. The rear sleeve for the tension line is sewn all the way
around, completely closed. goodFold the sail to find the 12 & 6 o'clock points. For the kite in the picture, the top, black panel was folded so its ends matched and pinched on the fold to mark the 12 o'clock point. The sail was then stretched out to find the exact opposite point of the sail for the 6 o'clock point. Measure to find the bridle points in between, Punch or burn a hole in the sleeve 3/8” back from the edge at every "hour" on the kite. Cut one slit in the rear sleeve at 6 o'clock.
push the stick
into the ferrule so that the ferrule is half on, half off) and put aside to
dry while you make the weights.
Make 6
weights, each with 5 pennies. Sew the penny weights evenly spaced between 5
& 7 o'clock, about
2" towards the back of the kite from
the leading edge sleeve. (Hint: 6 weights
= 5 spaces = 8 inches on center, for a 20 foot sail.)
Take the other end of the Secondary Bridle and thread it thru first the 12 o'clock bridle leg, then the 1 & 11 o'clock, then the 2 & 10 o'clock, then the 3 & 9 o'clock. Adjust so the mark on the Secondary Bridle is just showing away from the loops, and tie closed with several half hitches. Last bridle thing: Make a knotted loop by taking 12" of string and tying it closed with an Overhand Knot. Lark's Head (actually, a Prussik Knot is better to use if you know how to tie it) it to the Secondary Bridle. I fly mine close to the bottom. Identify the rear tension line. On one of the marks, pinch the mark and tie an Overhand Loop. Lark’s Head the Loop to a dowel fid and thread it thru the rear sleeve. Pull out the loose end, thread it thru the loop, pull to mark, and tie off. Pull all excess back into sleeve. Note: The relationship of bridle to kite is linear. These values are scalable. For a kite twice the size, double these values. This factor should be applied to the bridle, the circumference, the depth, the amount of weight, and the thickness of the leading edge spar. Note: The Bridle Table does not allow for Lark's Heads around the leading edge spar. If Lark's Head knots are to be used, add 3/4" to the Finished Length dimensions. No change in bridle length needs to be made if using the 'extra' sleeve and tabs. Gary Engvall (401) 942-3606 E-mail: gengvall@cox.net |
