## What is 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.
