Linear bearings and alignment method for weight lifting apparatus

A method for aligning a weight system comprising the steps of:

• providing a laser;
• providing an alignment tool having two linearly spaced apart alignment apertures;
• providing a bearing block with a first surface, at least one bearing block threaded through-hole, and a bearing block center aperture;
• providing jack plate having a jack plate center aperture;
• mounting the laser to the first surface of the bearing block such that the laser is centered with the bearing block center aperture;
• mounting the alignment tool to the jack plate such that the two linearly spaced apart apertures are centered with the jack plate center aperture;
• providing an adjustment mechanism;
• emitting a laser beam from the laser in the direction of the bearing block center aperture, the jack plate center aperture, and the two linearly spaced apart a ligament apertures;
• inserting the adjustment mechanism through the at least one bearing block threaded through-hole to make contact with the jack plate;
• and
• aligning the bearing block with the jack plate by adjusting the bearing block relative to the jack plate by tightening or loosening the adjustment mechanism until the laser beam is centered within the linearly spaced apart alignment apertures.
