ABSTRACT:
An especially configured angle plate apparatus having a workpiece holder mounted thereon for precision positioning of the workpiece holder relative to a supporting surface. The angle plate and workpiece holder are cooperatively adapted so that the workpiece holder may be precisely and selectively positioned in parallel relationship with the supporting surface, perpendicular relationship with the supporting surface and angular relationships with the supporting surface and all at adjustable distances relative to the supporting surfaces. The angle plate apparatus is also provided with fixed V-block structures and an adjustably movable V-block structure for holding and supporting workpieces and a special grind stone dressing tool for precision dressing of a grind stone.
