step

1. Take a piece of light wood, and process it into 15cm, 2cm wide and 0.6cm thick wood chips with a saw and other tools.

2. Measure the center position of the block with a ruler. Mark the center point with a pen, and then draw a line at about 1.0cm on both sides of the center point (the top and bottom of the box should be drawn).

3. Cut the diagonal part into an inclined plane with a utility knife.

The treatment method is as follows:

Use a small saw to make a cut in the upper and lower parts of the scribe line.

(1) The upper kerf on the left side requires "low outside and high inside", and the lower kerf requires high outside and low inside.

The upper kerf on the right side is "high outside and low inside" and the lower kerf is "low outside and high inside".

The depth of the kerf at the lower end is 0.2 mm from the bottom surface of the bottom chip.

⑵ Use a utility knife to cut off the surplus wood from the kerfs on the left and right sides to the center.

4. Drill a small hole in the center of the block with a hand drill.

5. Take a wooden stick about 14cm long and cut the upper end to a suitable size.

After coated with white glue, insert it into the central hole of the bamboo piece.

6. Twist the bamboo stick at the lower end of the bamboo dragonfly for flight test.
