Board kite practice

To make a product, you must first conceptualize it in your brain, envision its shape, then draw a drawing, and then make it according to the drawing. Making a kite is no exception. First of all, you have to conceptualize what type of kite to make and determine its shape, and secondly, you have to draw a sketch of the structure. The design of the pattern should conform to the principle of kite flight. The dimensions of the thickness, thinness, length and shortness of each part of the skeleton should be marked on the pattern as a basis for processing.

The production of the diamond-shaped plate kite, designed in Figure 1: (Figure marked dimensions are in centimeters)

Two, the choice of materials:

According to the design, choose two 0.6 × 0.5cm thickness, length of 75cm or so of the bamboo sheet two, bamboo joints should be long, to be another optional 75 × 75cm nylon silk a piece of fine line a number of spare.

Three, bamboo strips of chipping:

The first electrician knife (knife should be sharp) will be bamboo knots, and then the gabion will be more than one gabion yellow with the method of removal, the basic design to achieve the thickness of the bamboo strips, and will be the bamboo strips of the two sides of the design of the width of the chipping to the light. The whole piece of bamboo must be processed to flat, smooth, thick and thin as much as possible, do not like sharpening pencils like a small piece of a small piece of gnawing, so that the cut is impossible to do smooth and uniform thickness. Processed bamboo strips, in addition to measuring with a ruler, skilled can also be used visually, and can be used to pinch two fingers bamboo, from one end of the slide to the other end, with the sense of touch to find out the uneven thickness of the place, and then processed. Basically meet the requirements, and then file the bamboo part of the file flat, and finally use sandpaper to lighten.

Four, the skeleton of the binding:

After cutting the gabion, first cut off the length requirements of 65cm, 72cm, and then in the 65cm gabion marked 13cm, 15cm marking, 72cm gabion marked on the center point. Then the 72cm center point and 13cm marking point according to the cross-shaped cross tie. When winding the cross direction of each winding 3-4 turns can be, and drops of quick-drying glue fixed. (See Figure 1.) Finally, tie the line at the 72cm gabion end point and pull it to bend or bow it. Pull the line through the 15cm marking point (see Figure 2). Knot the thread and then sequentially pull the thread through the end points of both gimps to make a rhombus, with the top two sides of the rhombus equal and the bottom two sides equal. (Not all four sides are equal.) The tension should be moderate, not too loose or too tight, which will deform the skeleton. When the measured dimensions meet the requirements, drop the quick-drying glue, a diamond-shaped kite skeleton is completed.

Fifth, the kite framing:

Firstly, the prepared fabric is flattened on the desktop; then the front side of the kite skeleton (the gabion side) is coated with Baeder's glue (or white glue), and the pulling lines on the four sides should also be coated with the glue, and then the skeleton of the coated side is carefully put on the flattened fabric and pressed a little bit side by side, so as to make it sticky; finally, the kite is turned over, and the paste is checked to see if it is flat or not, firm. If there are wrinkles, it can be flattened moderately; if there is leakage of glue or de-glueing, small bamboo pieces can be used to stick on some glue to make up the glue. You can leave 0.5cm of the backside of the kite on the four sides, cut off the excess, then apply glue and fold the backside on the line to make the kite's sides straight.

When the laminating is finished, you can draw the pattern you envisioned on the surface of the kite, such as a rose, a cartoon character or a flying bird. The pattern can be whatever you want, as long as you find it interesting yourself. Of course you have to be careful when you draw the picture, you have to proof and color it so that it looks and feels colorful and lifelike before you can do it. You have to treat the kite you make as a craft. Since you are a beginner, you don't have to be overly obsessive. When everything is finished, you can also paste one or two colorful ribbons of 50cm long and 4cm wide at the lower end of the kite to increase the beauty and stability of the kite (see Figure 4)

Sixth, the layout of the kite's outline line (also known as the middle line or lifting line) and the test flight

This is a board kite without a tail, and it only needs two outline lines, each line is about 1.5 times of the length of the kite. Each line is about 1.5 times the length of the kite. The upper line is tied at the intersection of the two gabions, and the lower line is tied at the lower third of the longitudinal axis gabion. The upper and lower lines form an approximate right triangle with the longitudinal axis of the kite, the upper line is basically perpendicular to the plane of the kite, the lower line becomes the hypotenuse, and the intersection of the two lines is fixed with a knot. After this work, you can use the release line to test fly. If the test flight is not stable, you can tie an adjusting line (i.e. horizontal line) on the bow-shaped gabion with the center as the point, which is 6 to 8cm long. The top line can then be attached to the cross line and moved from side to side to adjust the center of gravity of the kite. If the kite is deviated to the left, then move the upper outline line to the left a little; if the kite is deviated to the right, then move it to the right a little; (after adjusting, use glue to fix it); if the kite is far away but not high, then shorten the upper outline line; if the kite is high but not stable, then shorten the lower outline line.
