The shuttle (54) is then moved to place a free end of each of the pins (20) in a gripped position within an insertion apparatus (55). The shuttle (54) is manipulated so that the shank portion (24) is allowed to return to a normal axis of each respective pin (20). The shuttle (54) is then removed from about the pins (20). ## Claims ### Claim 1 A pin supporting shuttle for supporting pins in a predetermined uniform spacing where each pin has a shank portion with a tip, which comprises: means for enclosing an intermediate section of each of the pins while maintaining the uniform spacing therebetween;
