Week 5 – Back work and Sound Hole

Posted on March 11, 2015December 1, 2019 by Iain 'Cutty' Carlin

Attaching back braces

  • Use block plane to round off back reinforcing strip, sand to get good finish
  • Cut slots in back reinforcing strip using template to mark distances
  • Saw through slightly and then use 6mm chisel to cut out
  • Plane tops of back braces to an angle so that the top is 4mm wide, but the bottom retains its original width
  • Glue the back braces in between the cut slots and use the go-bars to hold in till dry
    • 2nd from bottom brace goes in first then check it is square with the reinforcing strip
    • Put in the last 3 braces, measuring the distance between left and right sides with the first strip to ensure parallel

 Front work

  • Thicknessed the sound board to 2.5mm on the sander so that inlay is flush with top
  •  Cut sound hole using circle cutting jig. Gently at first and done from both sides till the circle can be pressed out of the hole.
