This is very easy way of making nice twisted wire. We should use soft wire, engraver, vice and hook.
Fold the wire in half and press 2 end in the vice. Pull the hook into the loop and engage the engraver at low speed.
If you use too thick wire, it's best to rotate it manually, not a tool. This twisted wire is too hard. So you can use butane torch to heat it and make it soft.
