The back has been carefully positioned, orienting it to the body according to the center seam and longitudinally. Each brace end is precisely scribed to indicate its proper trimmed length and its location is also scribed on the rim of the guitar.
Andy is shown notching the pocket in which the brace end will fit snugly. Notice that the end of the brace which he is fitting sits very close to the pocket for accurate reference and a perfect fit.
When all of the brace ends are properly fitted, the back is positioned on the rim and is scribed on it’s underside, around the perimeter of the guitar. The excess on the back is cut off on the bandsaw and the ends of the back support graft are trimmed to length.
