Making method of crossbow and drawing video course

First prepare materials: a pole, an electric drill, a board, several nails, a rubber band, a hammer, a marker and a chisel.

Production method:

1. Make a mark in the middle of the pole with a colored pen first, then put one end of the board near the pole to make a mark, and fix the pole and the board together with nails and hammers.

2. Use a chisel to cut a wooden trough with strip structure in the middle of the board, starting from the position where the pole is connected with the board, the length must be appropriate, and the finished wooden trough should be polished smoothly.

3. Drill a hole at each end of the pole with an electric drill, then pass the rubber band through the hole and fasten the two ends of the rubber band.

4. Nail a nail at the farthest end of the wooden trough, and then pull the rubber band to the nail position, so that the rubber band can pull the shoulder pole to bend, thus making a simple crossbow.

When making crossbows, it should be noted that the rubber band must be fixed and have a certain tension, so that the crossbow will have strength and can launch the arrow further. At the same time, the finished wooden trough should be polished smoothly, and the rough wooden trough will affect the speed of the arrow going out.
