Pointing Wire Needles

A hardened metal wire is given a bullet nose point by holding the wire under severe tension while heating it with a high temperature name.

One end 1 of a music wire is tightly clamped while force is exerted at the other end 2 to put the wire under tension. While the wire is under tension, a high temperature flame 3 is held near the wire. As a result of the heat and the tension, the wire is severed adjacent the flame 3. The severed ends of the wire have the bullet nose configuration shown in the above drawing.

This configuration is suited for the threading of core planes. Thus, the portions 1 and 2 of the wire can be used as needles for threading of core planes by attaching them to the wire to be used in the core planes and threading them, bullet nose first, through the cores.
