Improvements relating to tactile ground surface indicators
There is disclosed a method of manufacturing a tactile ground surface indicator having a head and a downwardly projecting member connected to the head to be fixedly receivable by a cavity formed through a ground surface for anchoring the head over the ground surface, in which method an element defining the downwardly projecting member or from which that member is to be derived is positioned such that an end portion thereof extends through an opening formed through a piece from which is to be derived an exterior portion of the head arranged to be visibly exposed when the head is anchored, and plastic deformation of either or each of the end portion and the piece is effected whereby there is created an interlock between the piece and element in which a plug portion of the element precludes downward withdrawal of the downwardly projecting member from said head, the method including directly mounting said piece to a machining apparatus and machining said piece using the apparatus to form a profile of said exterior portion. 14 --- 12 8 27~ 8 / 7A 5A? = 16' 10 10--- -15 17------ 5A 1 05 5 19 FIGURE 5 5A
