Interlocking tool for forming stator winding end turns

An interlocking tool for forming stator end turns comprising:

• a first member including a first base having a first surface and an opposing second surface, a first ring extends from the first surface and a second ring extends from the first surface radially outwardly of the first ring, the second ring being spaced from the first ring by a first gap;
• and
• a second member including a second base having a first surface portion and an opposing second surface portion, a first ring element extends from the first surface portion and a second ring element extends from the first surface portion radially inwardly of the first ring element, the second ring element being spaced from the first ring element by a second gap,
• wherein the second ring is positioned in the second gap, and the second ring element is positioned in the first gap, the first member being rotatable relative to the second member.
