An improved method and apparatus for media blasting a workpiece 20 is described. The media blasting apparatus 10 of the present invention includes a media reclaim and recycle system 35 , which reduces media wastage, advantageously improves peening of a workpiece 20 and provides better coverage of the workpiece surface. The media blasting apparatus 10 also includes a pressure chamber 90 for creating a media blast stream, a media metering valve 105 for controlling media flow rate and a powered part hold-down apparatus 130 for holding the workpiece 20 in a predetermined position during a blasting operation. The controlled media flow rate in combination with the powered hold down of the workpiece 20 ensures even and thorough peening of a workpiece surface.

[ What is claimed is:] [1.]1. A method of processing a work piece in a peening process with a media blasting stream comprising the steps of:providing a pressurized blasting system;directing a recycled media mixture at a work piece, said recycled media mixture comprising a mixture of virgin media and recycled media which have been used in a previous blasting operation;collecting said blasting media;separating said blasted media into media of a predetermined range of sizes for reuse in further blasting operations and media of a size insufficient for reuse in further blasting operations;monitoring a supply of virgin media;regulating introduction of virgin media in relation to a supply of said blasted media; andmixing said predetermined size range blasted media with virgin media to produce a recycled media mixture for use in processing a work piece.
