Abstract
A well bore liner is carried on a working string into a main bore of a well. A well bore liner is directed from the main bore into an auxiliary bore of the well with a whipstock. The whipstock is coupled to a working string without withdrawing the working string from the main bore. The whipstock is then relocated in the well using the working string.
