Raker File

Stop guessing file size, angle and raker depth. Raker File is an offline-first sharpening record and spec reference for arborists and firewood cutters who touch up saw chains in the field or at the woodpile. TOOTH GAUGE The app opens on a fullscreen side-profile drawing of one cutter and its raker (depth gauge). Adjust it directly: • Drag the handle on the raker tip to set raker clearance in thousandths of an inch or in mm • Turn the knob on the cutter to set the top-plate filing angle • Pick your round file diameter with the chip selector The drawing redraws live and turns amber or red when a value drifts outside your chain's spec. SPEC CHECK Set each chain's pitch and gauge, and Raker File shows the recommended round file size, top-plate angle and raker clearance to aim for. LOG TOUCH-UP One tap saves the session against the chain you selected. Record strokes per tooth, which side you filed, whether the rakers were checked, and a short note about hitting dirt, nails or rock. LOOP TRACKER A circular strip of drive-link teeth lets you tap each cutter as you file it, so no tooth gets skipped. Progress is saved if you are interrupted. CHAIN RACK AND HISTORY • Keep a list of your chains with saw, bar length, pitch, gauge and cutter type • See a sharpening-count badge and wear meter for each chain • Review a timeline of every sharpening with the numbers used • Follow a trend chart of cutter length remaining until retirement RETIRE ESTIMATOR Enter a minimum cutter length and the average length lost per sharpening to forecast how many sharpenings a chain has left. FILE SIZE CHART A searchable table of pitch to round file diameter, with a quick-fill that applies the size to the Tooth Gauge. REMINDERS AND WIDGET Get a notification after a set number of cutting hours or tanks of fuel logged. A home-screen widget shows which chain is due next. BUILT FOR THE STUMP • Works fully offline • Inch or mm units • Left-handed layout • Dark, high-contrast outdoor theme • JSON export and import through the system file picker for backups Raker File is a sharpening log and reference guide. Always follow your saw and chain manufacturer's specifications and safety instructions.
