Smithy Lathe/Mill/Drill

Has anyone out there ever done any CNC modifications for these
machines...or know anything about them? They are available now as
"cnc" ready. You can purchase optional CNC packages (including
fourth axis control) for them but I doubt if it controls the Z axis.
This looks like a really interesting machine. The lathe would make a
great "replacement" for my existing lathe ...well maybe an add on
:)... for my barrel work and I'd be able to do my wax pattern
machining and possibly small mold manufacturing on it too.
