length  of  tape  of  the  same  thickness  and  width as  that  of  the  broken  tape.  When  a  tape  is repaired,  it  is  best  to  use  a  good  section  of  the tape   for   calibration   (matching   a   whole-foot mark).   Place   the   section   used   for   calibrating beside the broken section to make sure that you will maintain the original length of the tape after rejoining  it. In splicing a broken tape, first align and rivet place  the  repair  stock  on  the  face  of  the  other section  of  the  tape  by  using  the  calibrating  section as a measure for the break splice. Insert one rivet at a time and arrange rivets in a triangular pattern. Do  not  place  rivets  closer  together  than  one-fourth in.  from  center  to  center.  Now  use  a  three-edge file.   File   partially   through   the   surplus   stock diagonally  across  the  tape.  The  segment  of  the surplus  will  readily  break  off,  leaving  a  clean the  repair  stock  at  one  end  of  the  break.  Next, splice.
