8. A method for installing a slip assembly in a structure, comprising:
running the slip assembly into place in the structure;
setting the slip assembly, including:
holding a helical slip of the slip assembly against axial movement;
wedging a core of the slip assembly into a bore of the helical slip, to apply a force that acts to radially enlarge the helical slip; and
engaging an outer surface of the helical slip with a wall of the structure; and
locking the core into the helical slip, wherein locking is by engaging interacting ratcheted surfaces on each of the core and within an inner diameter of the helical slip.
