Week 3 – Reinforcement and Sound Hole Sculpting

Posted on by Iain 'Cutty' Carlin

Back reinforcing strip

  1. Glue reinforcing strip made from cross cut strip taken from guitar top/front.
  2. Burr side up and overlap top and bottom ends on back and glue down. Won’t necessarily be a strip the whole length of back so glue a shorter strip if necessary. Hold down with masking tape.
  3. Clamp down using the clamping/joining jig for 5 minutes. Cover with paper to prevent wood from sticking to clamp bar
  4. Remove clamps and wipe off excess glue and re-clamp for 1 hour

  2. Identify and mark the top side of both halves.
  3. Long plane both top and bottom halves along the join edge.
