Abstract: A spring-loaded waste shield and cleaning aid has a moving block, a fixed block, a blocking flange, and at least one spring and linear bearing that form an elastically biased friction fitting plate. When inserted between vise jaws, the friction fitting plate will compress and expand so that a work piece can be clamped in the vise or removed without the plate falling out. The friction-fitting plate provides a work-underlying shelf that: shields function-critical vise components from machining waste and is readily cleaned; supports and positions a work piece; will catch small parts, tools, or the like accidentally dropped onto the shelf for easy retrieval; and is sacrificial in the event of accidental impact or contact with a machining tool or other mishap. In some embodiments, parallelepiped geometry, a socket head shoulder bolt, and appropriately sized components ensure that force overload applied by a vise does not damage the apparatus.
