Production of tt\ifmmode\bar\else\textasciimacron\fi{} by gluon fusion fullowed by t\ensuremath{\rightarrow}${\mathit{bW}}^{+}$, t\ifmmode\bar\else\textasciimacron\fi{}\ensuremath{\rightarrow}${\mathit{bW}}^{\mathrm{\ensuremath{-}}}$, and ${\mathit{W}}^{\ifmmode\pm\else\textpm\fi{}}$\ensuremath{\rightarrow}${\mathit{e}}^{\ifmmode\pm\else\textpm\fi{}}$${\ensuremath{\nu}}_{\mathit{e}}$(\ensuremath{\nu}${\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}_{\mathit{e}}$) is studied to extract the CP-violating chromoelectric dipole moment form factor of the top quark. The fact that the spin of the top quark, in its rest frame, is in the direction of the ${\mathit{e}}^{+}$ momentum facilitates the analysis. Expressions for the differential cross section and decays are given. We find that the Superconducting Super Collider or Large Hadron Collider, it is possible to put a limit of ${10}^{\mathrm{\ensuremath{-}}20}$${\mathit{g}}_{\mathit{s}}$-to ${10}^{\mathrm{\ensuremath{-}}19}$${\mathit{g}}_{\mathit{s}}$ cm on these effective couplings through the use of ``optimal observables.'' Naive observables such as simple triple product correlations are typically an order of magnitude less effective.
