He films on graphite show evidence of layered growth with increasing number density via a
succession of first-order phase transitions. These so-called ``layering transitions'' separate uniformly covering
phases, such as monolayers and bilayers. The present work is a detailed theoretical study of such layering
transitions using a Maxwell construction. We model the graphite surface by a strong substrate potential, and
using a microscopic variational theory we obtain the uniform coverage solutions for liquid helium. For each
layer, the theory yields the chemical potential and surface tension as functions of coverage n, and from
