Abstract
Fitting a shroud band to the tenons located at the tips of a blade of a turbine uses a jig. The precise location of the tenons relative to pitch, radial and axial location is determined by fingers which can interlock with an elongated segment. The fingers have apertures which define the position of the tenons. The apertures in the fingers are transferred to a shroud band into which apertures are formed. The shroud band is progressively apertured to form a long arc shroud for adjacent blades of the turbine.
