A method for mechanically securing turbine blades to mounting bands to form compressor stages. The turbine blades have end tangs which protrude through preformed slots in the bands. According to the method, a washer is pierced from stripstock and driven onto the end tang such that the tang stabs or pierces through the washer as the washer is driven flush against the band. In the preferred embodiment the washer stripstock is a composite; i.e., it includes its own brazing material which melts and braizes the blade to the band in a subsequent operation. An apparatus for carrying out the method comprises a blade seat, a stripstock retainer and a mechanically driven punch which substantially simultaneously punches the washer out of the stripstock and drives the washer onto the end tang of the blade.
