A precision assembly table and method includes a plurality of rigid bars connected to adjustable support members which can individually adjust the position of the rigid bars above a surface and a frame to create a desired contour. The structure to be assembled, such as a magnetic levitation guideway, is positioned and held in place on top of the rigid bars which have been positioned so as to define a desired contour of the structure and to which the structure will mechanically conform. The position of the rigid bars is monitored and adjusted by a computer to maintain the desired contour while the structure resting on the rigid bars is being assembled.

[What is claimed is:] [1.]individually adjusting a plurality of rigid bars to the desired contoured surface of a portion of a structure on a precision assembly table comprising said plurality of rigid bars whose position is capable of individual adjustment to define said desired contoured surface;positioning said portion of said structure on said plurality of rigid bars;holding said portion of said structure in position on said plurality of rigid bars disposed to form the desired contour with a hold down fixturesuch that said structure mechanically conforms to said contoured surface established by said plurality of rigid bars; andconnecting any remaining portions of said structure to said portion of said structure positioned on said precision assembly table after said portion of said structure has conformed to said desired contoured surface to form a contoured structure;measuring the position of said rigid bars during assembly operations; andadjusting the position of said rigid bars so that their position conforms to said desired contour.
