for a more detailed explanation (and some images)

Gimbal lock is the loss of one degree of freedom in a three-dimensional, three-gimbal mechanism that occurs when the axes of two of the three gimbals are driven into a parallel configuration, "locking" the system into rotation in a degenerate two-dimensional space.
The term gimbal-lock can be misleading in the sense that none of the individual g...

don't rotate stuff 90 degrees on the y axis

#

or make another bone in that rotated bone that isn't rotated (and animated that new bone)
