Crack Repair
Crack repair is a crucial skill in musical instrument repair and restoration. It involves fixing breaks, splits, or cracks in wooden instruments like violins, cellos, guitars, and other stringed instruments. This process requires careful attention to detail, as improper repairs can affect the instrument's sound quality and value. Repair technicians use various methods including gluing, cleating (adding small reinforcement pieces), and sometimes filling to restore the instrument's structural integrity while maintaining its acoustic properties.
