Abstract
A work holder for locating a workpiece of arbitrary or irregular shape during treatment comprises a flat horizontal table in which is mounted a two-dimensional array of vertically disposed spaced-apart rods which protrude upwards through the surface and can be moved upwards individually, either manually or by springs or by fluidpressure means such as rams, then clamped in position so that their tips form a cradle conforming to the shape of the workpiece, in which the workpiece rests.
