Bitting Chart

Bitting Chart is an offline-first locksmith rekey bench sheet built for locksmiths and cylinder techs who pin one named job at a time. Cold start opens a fullscreen pin-grid for the active cylinder so you can lock bitting, keyway, pin stacks, and cylinder count at a glance—and pin right the first time. BUILT FOR THE BENCH, NOT FOR NOTES This is a pinning chart, not a generic notepad, key catalog, or job journal. Columns are pin chambers from tip to bow. Rows stack bottom pin, master pin(s), and top pin lengths under the keyway profile and cut-depth line. Tap a cell to set cut depth or pin length. The grid recomputes stack height against the shear line and flags problems before you load the plug. LIVE PIN-GRID • Chambers as columns with tip-to-bow labels and keyway profile header • Bottom, master, and top pin rows with live stack totals vs plug diameter • Per-position cut depth entry with instant recomputation • MACS (maximum adjacent cut specification) violation highlights across neighboring cuts JOBS YOU CAN TRUST AT THE VISE • Named rekey jobs with keyway code, system (KW1, SC1, WR5, and more), cylinder count, and finish notes • Pinning kit picker: common pin sizes per system with quick-fill from cut depth to bottom pin • Multi-cylinder copy: duplicate bitting across N cores on the same job with per-cylinder checkmarks • Job history with search by site name, keyway, or bitting string—reopen any chart fully offline FAST FIRST RUN Seed sample jobs (office KW1 6-pin, apartment SC1 master, padlock rekey) so you can try the grid immediately. Preferences cover default pin system, chamber count, units (inch thousandths), and grid density. Whether you are master-pinning a multi-core system or rekeying a single cylinder, Bitting Chart keeps the live stack, cuts, and MACS checks on one glanceable sheet so the work leaves the bench correct the first time.
