Woke up thinking about this today...I know, I know; things usually go tango uniform when I think too much.
The "OD Groove" wizard in the standard Lathe Turning Wizards page already has all the pecking, depths, etc. needed for X-axis drilling but the "Groove Width, "Tool Width" & "Stepover %" input boxes screw things up. I tried but wasn't able to cheat the box inputs to get it to work. Would it be a huge VB editing job to kill those boxes and still have the needed inputs working? Like my Pappy used to say: "Shouldn't be a hill for a stepper, son."
