A method for positioning and fastening a second object (21) in a first object (14), the first object being provided with a seat for said at least one second object, both objects being made of a non-metallic materials. The method comprises forming at least part of the walls of the seat, preferably the circumferential rim, from a liquidifiable solid material (26) which is at least once reversibly liquidifiable by heating it, said solid material being other than said non-metallic materials, placing the second objects into the seat, liquidifying said solid material by heating it so that the latter material attaches the first object to the second object, and allowing said liquidifiable material to cool and resolidify, said liquidifiable material thereby forming a bond between the first object and the second object. |
