We present a new analysis method which directly reconstructs the $W$ charge asymmetry using $W^{\pm} \rightarrow e^{\pm} \nu$ decays at the Collider Detector at Fermilab. The $W$ mass constrains the unknown longitudinal momentum of the neutrino from the $W$ decay, leaving two possible $W$ rapidity solutions. We determine the relative contributions of the two solutions for each event according to the V-A decay structure of the weak interactions, resulting in a determination of the $W$ boson rapidity spectrum.
