Claim:
A wire spool, comprising: an elongate barrel having a longitudinal rotational axis, the barrel has a first end and a second end that are separated by a wall with an inner surface and an outer surface; a first flange that is toroidally shaped and is substantially orthogonal to the longitudinal rotational axis, the first flange is disposed concentrically surrounding the first end of the barrel; a second flange that is toroidally shaped and is substantially orthogonal to the longitudinal rotational axis, the second flange is disposed concentrically surrounding the second end of the barrel; a key that is disposed on the inner surface of the barrel, the key is a rectangular prism that extends from the second flange toward the first flange along the longitudinal rotational axis; a recess that creates a hole shaped as a rectangular prism within the key, the recess is smaller than the key; a hook slot that is disposed within the outer surface of the barrel, the hook slot is located above the recess and receives a wire with a start end and a length of wire to be wound, the hook slot includes, a straight segment that directs the start end into the recess in a first direction; a transition that receives the length of wire to be wound from the straight segment and directs the length of wire to be wound approximately ninety degrees relative to the first direction, the length of wire to be wound is opposite the start end; and an exit pocket that receives the length of wire to be wound from the transition and directs the length of wire to be wound out of the hook slot and against the second flange.
