(1) Tool preparation: soldering gun (electric soldering iron), solder paste, solder wire, No. 1-5 Iseni hook, two pieces of wood (used to make simple molds), clamps, flat file .
2) Mold making: Make a cylindrical notch 2 mm deep, 4 mm wide, and 8 mm long at the edges of the two wooden blocks (if possible, you can clamp the two wooden blocks first, Drill with an electric drill).
(3) Hook tail surface treatment: The surface of the hook has a coating, which is difficult to weld with tin if it is not removed. The treatment methods can be file filing, iron sandpaper grinding, blade scraping, etc., as long as the surface coating can be removed That’s it.
4) Soldering the tin: First, stick some solder paste on the hook tail, put it into the mold, and clamp the two pieces of wood with a clamp. Second, use a welding gun to melt the wire into the mold notch. Finally, after the solder has cooled, take out the upward hook made in rough steps.
