Luthier Toolkit

Luthier Toolkit puts the numbers you need at the bench in one place: fret positions, string tension, radius, spacing, neck angle, compensation and more, with printable full-size templates and records for every instrument you build or set up.

BUILD • Fret positions for any scale, with a printable 1:1 slotting template • Multiscale (fanned) frets with nut and bridge angles and a full-size template • String tension from published unit weights, with balanced sets matched to any string, multiscale and custom string counts • Compound radius, edge drop and cross-sections • Nut and bridge string spacing, equal gaps or equal centres, with a printable template • Neck angle and saddle height • Saddle compensation per string • Plate thickness by deflection and stiffness • Air resonance of the body • Tap tone: live spectrum and tap capture with peaks and notes

SETUP • Chromatic tuner with needle and strobe • Intonation: how far and which way to move each saddle • Published factory setup specs • Wiring diagrams with parts and lead colours

RECORDS • Instruments you build or work on: specs, strings, setup history, truss rod log and photos, with a one-page setup sheet • Humidity log with safe range and wood moisture

REFERENCE • 60 tonewoods: density, hardness, stiffness, speed of sound, shrinkage • Fret wire sizes with refret wire length • Wood movement from humidity • Fraction calculator, board feet, shellac, epoxy and hide glue mixing

Every tool explains itself: a short guide the first time you open it, and ⓘ notes on the fields.

Inches, fractions or millimetres throughout. Works offline. No account, no ads, no tracking.
