Card trick kite

Materials List:

4 x 100cm CFRP 6mm ø

4 x 82.5cm CFRP 6mm ø

3 Pole Connectors

2 Eddy Crosses

approx. 2m sail material

Dacron for pole pockets and reinforcements

Sail:

The shape and size of the sail are based on the drawing. All measurements are without seam allowance. The design of the sail depends on personal taste. For example, I prefer a patchwork pattern. Reinforcements and pockets for pole attachment are attached to all corners (6). Dacron reinforcements are sewn onto the bridle points. Two straps are attached to the back (pole side) of each reinforcement. These are used to secure the center pole.

My suggestion for attaching the bridle cords:

Two eyelets are hammered into the reinforcements, one to the left and one to the right of the center pole. The bridle cord is threaded through the eyelets around the pole and knotted at the front.

Rods:

I assembled the center rod from four parts. The two Eddy crosses are attached in the appropriate places and secured to prevent slipping. The rods are adjusted so that the rods fit snugly, but not too tightly. Otherwise, the kite would flex excessively. Instead of the 6mm carbon fiber center rod I used, I could certainly use stronger rod material. This should allow the kite to fly even in stronger winds.

Bridge:

My bridle is a "random bridle." I placed my bridle points where several sail elements meet. The idea behind this is this: A composite bridle relieves the center rod of stress. No bridle points are needed to the left and right of the centerline. The kite stabilizes itself. The bridle can, of course, also be built to my specifications.
