BLOCKHEAD
1. Fold sail material in half and lay half pattern on top with the spine line on the fold. As I do
not hot cut I use a very sharp knife to cut out the sail. Now cut. 2. Unfold the sail and place
the face side dawn and, add the leading edge stiffener. i use strapping tape for Mylar, orcon
tape for orcan and I make ripstap tape using peel and stick. You also can cut the leading
edge larger than shown and fold it over using contact cement. If you want a real stiff edge
add a .03 carbon or some other stiff material.
3. Now install the spine. Lay a bead of contact cement down the centerline of the sail and the
side, of the spine you are going to use, facing the sail. Don't forget to let the contact cement
become tacky.
4. Put on the photo corners. I use the clear plastic ones.
5. Cut the. OS carbon rod to length. Maybe a touch longer. Place into the photo corners
and see if it comes to the end of the leading edge and crosses over the upper bridal point
spot. Grind to fit.
6. Now is a good time to place the reinforcements for the upper and lower bridle points. With
the bow lying on the spine, measure the distance out from the spine and place the
reinforcements.
7. Spread the contact cement on the fold over for the ends of the bow and the ends
of the bow. Let become tacky. Careful to lie the bow down then slit the material
from the bow out, about half way, Fold the lower material over the bow and burnish
down, then do the top half.
Place the reinforcement patches on the nose, tail and bow ends. Also place a small
patch where the bow meets the fold over flap.
However you make the holes for your bridle lines now is the time. Hope you
remembered to mark the spots,
Cut the 7inch upper bridle. Tie a knot on one end. Run the line thru some bees
wax a couple times. Place around the bow and tie a slipknot. Tighten and then run the line thru
the hole and back in the other side and tie a knot in the end of the line then tie onto the bow with
another slipknot.
11. Cut the bridle 22 inches then fold over one end about one and a half inches to two. And tie a
loop. Bees wax this line also about 5 times. Larks head this onto the upper bridle and tighten
trying to get close to center as possible. With the loose
end, put it thru the lower bridle point and bring it out the other hole to the front. Here I tie an
over hand knot then a slipknot. (Like your shoe laces.) Then push the loop thru on hole to the
back and then the tail thru the other. If it is waxed well enough you can spin the two together
and the will stick.
12. Now for the tow loop. I know some have bigger fingers so make it to your size, Larks head it on
the bridle and adjust so the nose is about 1 inch off the table with the tail touching.
13. Hope you enjoy this kite. Let me know if you build it and how you like it. Email me at
