Balancin Props

[Bootlegger]

   Mornin Guy's,
          First I must appologize for postin my question in the wrong place.
          I am curious about balancein props, I read to sand the "face" of the prop not the back.
          What is the reason for this ? My thinkin is that the airfoil is what makes the prop "work".
        Sanding the back changes the pitch though doesen't it ?
        Sure could use some help in this direction........

You're correct. For balancing, sand the "face" of the prop. You can ahieve a small amount of "re-pitching" through changing the angle of the "backside" of the prop, but any significant effort here will also reduce blade area.

Put on a latex glove and smooth super glue on the face of the light blade until it balances.
