Abstract
A compliant workholder for use with woodworking, metalworking, or other machinery which pushes against a workpiece with substantially constant pressure while moving in and out to accommodate variation in the size of the workpiece. Preferably, the workholder uses a feather board mounted on one or more sliding guide rods. Rollers, a low friction shoe, or other elements may also be used to contact the workpiece. A pneumatic cylinder is the preferred mechanism for applying outward pressure to the feather board. The workholder will retract on activation of a momentary switch by the user and will remain retracted for an adjustable time period to allow positioning of the workpiece.
