Transform raw timber into expertly measured string instruments with automated dimensional tracking and conflict resolution built for professional luthiers
Download JackbenchAccess proven dimension sets from professional builds. Each template saves hours of calculation and ensures accurate proportions from nut to saddle.
Templates apply saved proportions to new builds. All measurements remain fully adjustable. Timber selection and final dimensions are your design choices.
Jackbench calculates interdependent measurements across every component of a string instrument. When you adjust scale length, the software recalculates fret positions, saddle compensation, string spread, and board taper automatically. No manual math required.
The conflict detection system identifies dimensional impossibilities before you cut timber. If your nut width, string spread, and fretboard length create geometric conflicts, Jackbench flags them immediately with specific warnings about which parameters need adjustment.
Progress tracking monitors your build through seven distinct stages from stock selection to final setup. Record actual measurements at each phase and compare them against design specs. Version control lets you save states before major changes and restore previous configurations if needed.
Define nut, fretboard, frets, neck, body, and bridge measurements that update automatically when any parameter changes. All dimensions stay mathematically accurate across the entire instrument.
Real-time detection of geometric impossibilities. Color-coded status indicators show which components have issues, with specific feedback on margin conflicts and dimensional mismatches.
Automatic compensation values based on scale length and action height. Adjustable saddle positioning with calculated offsets for accurate intonation across all fret positions.
Track progress through stock selection, worked parts, assembly, bench finishing, and final setup. Document completed stages with timestamps and actual measurements at each phase.
Visual catalog of wood species with realistic grain patterns. Track which blanks cover required dimensions with status indicators for Sitka spruce, mahogany, rosewood, ebony, and custom species.
Save successful dimension sets as templates for future builds. Apply proven configurations including fingerstyle flat-top, low-action solid, traditional classical, and short-scale parlour setups.
Jackbench serves professional guitar makers, instrument builders, and technical woodworkers who need precision measurement management. The app handles complex interdependent calculations that would otherwise require spreadsheets or manual trigonometry. Conflict detection prevents costly material waste by identifying design issues before cutting begins.
