1. A modified honing brush comprising:
a brush hub having a face wherein said face of said brush hub has or a plurality of outwardly projecting bristles, wherein each of said bristles has a shaft having a length; and
a first plate having a first side, a middle section, and a second side, wherein said middle section of said first plate is disposed between said first side of said first plate and said second side of said first plate, and wherein said first side of said first plate is opposite to said second side of said first plate, the first side of the first place facing toward the face of the brush hub, the first plate having a plurality of holes or voids extending from said first side of said first plate, through said middle section of said first plate and through said second side of said first plate,
a second plate having a first side, a middle section, and a second side, wherein said middle section of said second plate is disposed between said first side of said second plate and said second side of said second plate, and wherein said first side of said second plate is opposite to said second side of said second plate, the second plate being removably stackable onto the first plate so that the first side of the second plate is adjacent the second side of the first plate in a stacked position and the second plate is also removable from the first plate, the second plate having a plurality of holes or voids aligned with the holes or voids of the first plate in the stacked position;
the shafts of the bristles being passed through the holes or voids of the first plate and the holes or voids of the second plate such that removal of the second plate from the first plate exposes a portion of the shafts that are within the holes or voids of the second plate adjacent to the second side of the first plate so a working length of the bristles is increased to account for wear of the bristles that shortens the length of the shaft of each of the bristles.
