It comes in two main forms: a handheld caul system that uses a C-clamp or specialized squeeze handle, and an arbor-press-mounted system with interchangeable radiused cauls. The caul has a curved underside matching the fretboard radius, ensuring the fret is pressed evenly across its full width. Inserts or cauls are available for all standard fretboard radii. ## Use in Lutherie Fretting is one of the most precision-critical operations in guitar building. Each fret must be seated fully and evenly in its slot for proper playability. The fret press offers several advantages over traditional hammer-and-caul fretting: it applies force straight down without risk of glancing blows, it seats the fret evenly across its width in one press, and it is quieter and less jarring to the instrument. The arbor press version is particularly valued for production work, while the handheld version is popular for repairs and one-off builds. ## Selection Guide The Stew-Mac fret press system is the most widely used in small shops. It includes a handle with interchangeable radiused cauls. For higher volume, an arbor press (0.5 to 1 ton capacity) with a fret press attachment offers faster, more consistent seating. Ensure you have cauls for each radius you work with. Budget 40 to 100 dollars for a handheld system, 100 to 250 dollars for an arbor press setup. ## Tips - Apply a small drop o…
