Model Overview When a guitar neck or headstock breaks, a simple glue joint often isn't enough. That’s where the Neck Spline Jig comes in—designed specifically to guide your router for creating precise spline channels that add critical structural support to the repair. Splines aren’t just filler—they’re reinforcement. By inserting hardwood splines across the glue joint, you dramatically increase the bonding surface and reduce the risk of future breaks, even under string tension. Why Use Splines? Added structural integrity to the joint Reduces flex and movement at the break Maximizes glue surface area for a stronger bond Ensures perfect alignment every time Features and Specs Guides your trim router for clean, accurate spline slots Easy setup and repeatable results Compatible with: Dewalt D26200 Bosch GKF600 Makita RT0700C Makita 3709 Pro Tip: Combine with the G&W Headstock Gluing Jig for the most stable and long-lasting headstock repairs possible.
