Tips

  • Use good quality wood glue for a stronger bond.
  • It doesn't need to be perfect; focus on getting a tight fit.

Common Mistakes to Avoid

1. Using the Wrong Type of Glue

Reason: Using a glue that's too strong or too weak can damage the tuner or prevent it from setting properly. Super glue can be difficult to clean up if you make a mistake and wood glue may not provide enough hold.
Solution: Use a strong, quick-drying wood glue specifically designed for small repairs.

2. Insufficient Glue or Improper Application

Reason: Not applying enough glue to the toothpick or not adequately distributing it around the tuner post will lead to a weak fix that won't last.
Solution: Apply a small amount of glue to the entire length of the toothpick, ensuring it's evenly distributed before inserting it into the tuner hole.
