  The scalar interaction term of the top mode standard model can be generated
by a gauge theory. It is emphasized that in this approach generalization to
family space directly yields a heavy top quark while leaving all other quarks
massless. By generating the new interaction from gauge extension to custodial
$SU(2)$, the standard model bound $m_{top} \stackrel{<}{\sim} 200 GeV$ is
pushed to $m_{top} \stackrel{<}{\sim} 270 GeV$, thereby significantly reducing
the amount of finetuning required to match this number.
