The turbine blades have end tangs which protrude through preformed slots in the bands. 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. Preferably the washer stripstock is a composite; that is it includes its own brazing material which melts and brazes the blade to the band in a subsequent operation. For carrying out the method a blade seat, a stripstock retainer and a mechanically driven punch simultaneously punches the washer out of the stripstock and drives the washer onto the end tang of the blade. |
