Linear bearings and alignment method for weight lifting apparatus

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

• providing a bearing block with a first surface, at least one bearing block threaded through-hole, and a bearing block center aperture;
• providing a jack plate having a jack plate center aperture;
• providing an alignment tool having a throughbore;
• providing an alignment rod;
• mounting the alignment tool to the first surface of the bearing block;
• inserting the alignment rod through the throughbore of the alignment tool, the bearing block center aperture, and the jack plate center aperture;
• providing an adjustment mechanism;
• 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 alignment rod is centered in the alignment tool.
