I am considering drilling a low flare Stinger with the pin in my track.  I am wondering whether any of you have a certain procedure for that drill pattern.  Do you place the pin 6 3/4" from your axis and measure back or do you have a measurement from your track to the midline?  Any thoughts would be appreciated.  I am drilling this ball with the intention of using it from outside angles on dry to very dry.  Thanks.
