Abstract
A method is disclosed of removing a plurality of rim blade dies around the circumference of a disc while the disc, blades and blade dies are at a temperature approximating those during the forging operation. The upper disc forming die is removed along with a restraining back-up member around the rim blade dies and the rim blade dies are forced radially outwardly to prevent interference between the blade dies and blades during their cool down period. A blade die removal tool has a plurality of individual radial arms extending outwardly from a central hub. The free ends of the arms engage the blade dies and the ram of the press moves the central hub downwardly to move the blade dies radially outwardly.
