  • making the wall of revolution interconnecting one of the disks and the annular flange so that it has a local annular extra thickness of material;

    then, once said wall of revolution has become deformed in use, cutting through the extra thickness and removing the wall; and

    positioning a new wall of revolution to take the place of the removed wall, and welding said new wall to the drum.
