ABSTRACT:
A precision guide assembly (11) comprising a receptacle (13) having an at least part-cylindrical passage (19) with an axis (27), a guide pin (15) sized to be inserted into the passage (19) of the receptacle (13) and having an axis (31). The guide pin (15) has a part-spherical head (33) and an at least part-cylindrical stem (35) joined to the head by a neck (37). The stem (35) and head (33) have substantially the same diameter and a lesser diameter than the diameter of the passage (19) so that the guide pin (15) can be slid into the passage (19). The neck (37) has a cross-sectional dimension less than the diameter of the stem (35) and an inclined surface (39) which is inclined with respect to the axis (31) of the guide pin (15) so that the inclined surface (39) extends radially inwardly as it extends distally.
