For this Barn Door, you need...
6 bamboo BBQ skewers, 30cm (12") in length
2 short 0.15SL (4.4cm, 1 3/4") lengths of skewer
2 short 0.25SL (7.3cm, 2 7/8") lengths of skewer
See the photo...
The photo below shows how the pieces of bamboo are all glued together. The skewers at the top of the photo form the horizontal spar. See how each tip is raised away from the table top. The short bits in the middle just lay flat against the table.
The other skewers form the 2 diagonal spars. These have all the bamboo lying flat against the table top.
To make sure there are no kinks at the joins, get your head down low and look along the spars. Shift one or 2 skewers a little, if necessary, before the glue dries!
All the construction details for the bridle are contained in the large photo below. Look and read carefully, and you can't go wrong on this rather important bit! Just use 20 or 30 pound flying line for the bridle pieces.
If you are new to this, you might need instructions on how to tie the following knots...
TIP: Secure the slip knots around the bamboo with a blob of wood glue, so they can't loosen.
Once your kite + bridle looks like the photo up there...
Adjust the Prusik knot that is closest to the kite. It needs to be as close to center as possible.
Next, hold the short bridle line up so all the bridle lines are straight, with the kite laying flat on the table or floor.
Referring to the diagram below, shift the other Prusik knot to the shown position. It's not necessarily the perfect position for your individual kite, but it should at least fly on the first attempt!
Later, you can experiment with shifting the position away from the nose a little at a time to improve how high your kite flies in light wind. Alternatively, you can experiment with shifting the position towards the nose more, to help the kite cope better in very windy weather.
Cut out a long rectangular piece of dark plastic for the tail. Black garbage bag plastic works well. Make it about 0.3SL (8.7cm, 3 1/2") wide and 12SL (350cm, 140") long.
Tie one end around one diagonal spar, and the other end around the other diagonal spar, as close as possible to the bottom tip in each case. See the photo on the right.
A single Half Hitch for each knot will do, since there are very low forces on the tail in flight.
You can see the full length of the tail in the 'Flying' photo further down...
At this point, you've finished making the 2-Skewer Barn Door!
To attach the flying line, just Lark's Head the flying line to the short bridle line as in the photo.
