I went to main city library and only 8 books on electrical anything
and nothing on coil winding or motors.
Any recommendations on practical teechnique ?

Motor coil rewinding is not recommended for a one-of repair! If you are
really serious, please know that you will make a substantial investment in
tools, materials and personal knowledge.

Yes, I have rewound stator coils and will never do it again! I have never
done a wound armature and know enough to avoid even thinking about it.
