[Boatanchors] Help on drilling out knob setscrew

[Al Parker]

Hi Lee,
    Go to a good hardware store and get a cupla small size left handed 
drills.  They might bite enough to turn the screw out, inside of tightening 
it like normal drills.  The hole probably isn't deep enough for using an 
EZ-out, which is left handed.
