I am looking for a AC yoke that will move in 3 directions.
Think X,Y,Z planes.
This would be like a Y-6 (Magnaflux) --OR-- B300 (Parker Research) or Yoke but the legs would be able to bend perpendicular to the body of the yoke.
Another way to describe it is a leg joint similar to a universal flex joint used in socket wrenches.
Purpose. Extra Confiuration flexibility.
