• the respective saddle of each of the hydraulic jacks fixed to the upper plate bottom at a respective one of the four upper plate corners,
• a first of the two floating rails extending along the upper plate top proximal and parallel to the first side, a second of the two floating rails extending along the upper plate top proximal and parallel to the third side;
• a first two of the four support brackets slidingly engaged with the first of the two floating rails, a second two of the four support brackets slidingly engaged with the second of the two floating rails, each support bracket configured to engage a workpiece positioned on the upper plate top,
• a first two of the four coarse threaded rod upper receivers positioned proximal to the second side, a second two of the four coarse threaded rod upper receivers positioned proximal to the fourth side, each respective one of the four coarse threaded rod upper receivers position above and in line with a respective one of the four coarse threaded rod lower receivers;
• the floating jack comprising a base and a saddle and configured to be positioned at a positioned at a point between the lower plate and upper plate, preferably between the lower plate center and the upper plate center, with base on the lower plate top and the saddle on the upper plate bottom;
• each one of the four coarse threaded rods threadingly engaged in a respective one of the coarse threaded rod upper receivers and the coarse threaded lower receiver in line thereof,
• each one of the four stabilizing nuts threadingly engaged with a respective one of the four coarse threaded rods, positioned between the lower plate and the upper plate, and configured to engage the upper plate bottom.

A method of servicing a large scale machine comprising:

• positioning a rigging table proximal to a component of the machine, the rigging table including:
• four bearing skates, four vertical supports, four horizontal supports, a lower plate, four corner hydraulic jacks, an upper plate, a floating hydraulic jack, four coarse threaded rods, and four stabilizing nuts;
• each of the vertical supports having a first end, a second end, a first horizontal support interface surface proximal to the second end, and a second horizontal support interface surface proximal to the second end each bearing skate fixed to the first end of one of the vertical supports;
• the lower plate comprising four lower plate corners, a lower plate top, a lower plate bottom, a lower plate center, and four coarse threaded rod lower receivers, each second end of the vertical supports fixed to the lower plate bottom at a respective one of the four lower plate corners;
• each of the horizontal supports comprising a first end, a second end, and an upper surface extending between a respective pair of the four vertical supports and along the bottom of the lower plate;
• each of the four corner jacks comprising a base and a saddle, and the respective base of each positioned at a respective one of the four corners of the lower plate and on the lower plate top;
• the upper plate comprising a first side, a second side, a third side, a fourth side, four upper plate corners, an upper plate top, an upper plate bottom, an upper plate center, two floating rails, four support brackets, and four coarse threaded rod upper receivers,
• the respective saddle of each of the hydraulic jacks fixed to the upper plate bottom at a respective one of the four upper plate corners,
• a first of the two floating rails extending along the upper plate top proximal and parallel to the first side, a second of the two floating rails extending along the upper plate top proximal and parallel to the third side;
• a first two of the four support brackets slidingly engaged with the first of the two floating rails, a second two of the four support brackets slidingly engaged with the second of the two floating rails, each support bracket configured to engage a workpiece positioned on the upper plate top,
