ABSTRACT In a hydrostatic support member with at least one pressure pocket in the head portion of the support member, the or each pressure pocket opening opposite a surface which is to be supported, the inner side of the lining wall which defines the pressure pocket relative to the environ ment of the support member is inclined relative to the pressure axis of the support member, so that the profile of the pressure pocket becomes larger towards its base. The outside of the lining wall extends relative to the inner side in such a way that when this wall is lowered towards the base the hydrostatically effective surface of the head portion, facing the surface which is to be supported, increases in size. A method of producing or finishing the support member according to the invention is proposed: The support member is first prefabricated with the head portion having a relatively small hydrostatically effective surface, compared with an operational one, the walls having been made higher. It is then used under conditions which simulate actual operation. The prefabric- ated walls of the at least one pressure pocket being so lowered by a lapping type process. As the hydrostatically effective surface of the head portion increases in size during this lowering, the lapping stops automatically at the stage when the optimum operational hydrostatically effective surface for the head portion has been obtained.
