Slingshot gun, how to assemble

1. The thickness of steel wire should be determined when making steel wire. The length of the steel wire is 50 cm. After bending and merging, 10 cm is left as the handle.

2. Bend the two steel wires outward about 80 degrees from the upper end of the handle, taking two fifths of the distance, and then bend them upward for the second time, so that the top ends are bent into a circle.

3. After the slingshot frame is symmetrically formed, the two folding steel wires at the upper end of the handle of the slingshot frame should be tightly wrapped with thin copper wire and thick fishing line to prevent looseness.

4. Install rubber and elastic seat on the slingshot frame: circular rubber band and automobile inner tube can be used. Cut two 60-cm-long rubber strip with a meter ruler, symmetrically. The elastic seat can be made of cowhide or pigskin, and it can be strong.

5, 8 cm long and 4 cm wide, cut two seams at both ends and put them in the middle of the rubber. Put both ends of the rubber into the oblate shape of the fork head of the slingshot frame, and evert 2 cm each. Tie the everted part with the inner rubber with nylon rope, leaving a gap, so that the rubber strip and the steel wire in the oblate hole can rotate freely. The slingshot is ready.
