Abstract:
A method for preparing a first work piece to facilitate joining the first work piece to a second work piece using a finger joint, the method comprising:forming at least one finger on a first end of the first work piece;applying a coating to the finger of the first work piece;checking the coating applied to the finger of the first work piece to determine whether the coating includes an imperfection before the first work piece is joined to the second work piece using a sensing mechanism arranged to scan across at least a portion of the finger, wherein checking the coating includes obtaining luminescence data by scanning across the portion of the finger, the sensing mechanism being arranged to substantially reduce the luminescence data; andidentifiying the first work piece as including an imperfection when it is determined that the coating includes the imperfection.
