ok guys..question....am i supposed to simply use the screw as a wedge to tap inbetween these three peices? or do i actually screw the screw down inbetween them? ive made this tool you guys have shown me but when i turn the screw to wedge and expand the three peices to press against the ring and lip....the 3 peices keep spinning and turning out from catching the lip. haha man and ive tried to tap the screw in as a wedge but it just goes to one side or the other....cant get it to stay inbetween the 3 peices. i got a grab ONE time, and when i went to tap it out...the tool just popped off the lip. :::ulling hair out:::: WHAT AM I DOING WRONG????
