What is claimed is: 1. Apparatus for securely holding and manipulating a workpiece for construction or repair, comprising: a fixed and stable base: a pedestal fixed to and upstanding from said base, and having a vertically adjustable threaded post therein, means atop said pedestal and engaging said threaded post for moving said post vertically as desired, and means for locking said post into a desired position; a workpiece support assembly; means mounted between said pedestal and said workpiece support assembly for rotating said workpiece support assembly about a horizontal axis while holding the workpiece securely, comprising a first member having a worm gear housed therein, means for rotating said worm gear, a second member having a second gear fixed thereto and engaging said worm gear, whereby rotation of said worm gear moves said second member through an arc; means atop said pedestal for holding said workpiece support assembly which is U-shaped, and is removably attached to said pedestal; means for securely attaching an workpiece to said workpiece support assembly; means for pivoting said workpiece support assembly about a vertical axis while holding the workpiece securely; and mechanical means integral with said pedestal for moving said workpiece support vertically. 2. Apparatus according to claim 1, wherein said base has a plurality of fixed legs projecting radially. 3. Apparatus according to claim 2 wherein said base has associated wheels for mobility. 4. Apparatus according to claim 3 wherein said base is provided with stabilizing means for preventing mobility, said stabilizing means being a fold-out base support pivotally attached to each of said legs about a horizontal axis, which when pivoted into the stabilizing position raise the wheels to prevent their contact with a floor. 5. Apparatus according to claim 1 wherein said means for holding said workpiece support assembly is U-shaped, and is removably attached to said pedestal. 6. Apparatus according to claim 1, wherein said workpiece support assembly is an instrument support assembly adapted to support a stringed musical instrument, and wherein said instrument support assembly comprises: a bar holder; a bar having spaced holes extending therethrough both longitudinally and transversely; means for fixing said bar in said holder an instrument support plate having a plurality of holes therein; means for fixing said plate on said bar; means communicating with said bar for holding the end of an instrument neck; and adjustable pin means attachable to said bar for supporting an instrument neck. 7. Apparatus according to claim 6 wherein at least some of said holes in said instrument support plate are elongated slots having closed ends. 8. Apparatus according to claim 1 wherein said means for attaching a workpiece to said workpiece support assembly is a plurality of workpiece clamps, each of said clamps comprising: a pair of opposed jaws spaced on a support pin plate, each jaw having a workpiece contact end and a remote end; a threaded thumbscrew threadedly engaging one jaw and bearing against the remote end of the other jaw; and a pivotal workpiece contact member at the workpiece end. 9. Apparatus according to claim 8 wherein the workpiece contacting face of each workpiece clamp is provided with a cushioning substance. 10. Apparatus according to claim 3, further comprising a wheel locking mechanism on at least one wheel to maintain the apparatus in a desired working position.
