Finally, you have to drill from the face to the hook hole. The larger two sizes of this plug have offset line ties.
To get the angled hole to meet the center drilled hole in the hook hole I use a board with a nail to index the tail hole, offset the nail so the hole will travel at an angle to intersect the hook hole at the midline, and put a drill bit in the weight hole to help me keep everything aligned with the board. The tall nail in the picture isn't used for this plug.
