Our workbench focuses on exact mechanical restoration, eliminating skipped stitches and tension irregularities through disciplined calibration.
Hook timing & synchronization
Preventative overhaul
Motor & drive inspection
Full teardown and alignment of hook timing, needle-bar height, and feed dog clearances to eliminate skipped stitches across varying fabric weights.
Comprehensive ultrasonic cleaning of internal assemblies, complete removal of hardened grease, and lubrication using manufacturer-grade non-gumming mechanical oils.
Inspection of carbon brushes, foot pedal rheostats, internal wiring, and drive belts to ensure continuous motor torque and steady speed control.
Bench service protocol
Initial bench diagnostic
Deep clean and degrease
Mechanical realignment
Balanced stitch testing
We examine needle strike plates, assess bobbin clearances, and run initial diagnostic stitches on dense linen to isolate mechanical discrepancies.
Machine casings are opened to vacuum packed thread lint and purge varnished residue from drive gears, shafts, and shuttle races.
Hook-to-needle clearances and feed eccentric cams are set back to factory tolerances using precision feeler gauges and torque standards.
We balance upper and lower tensions across straight, zig-zag, and specialty stitches, returning sample sew-offs along with your tuned machine.
Bring your machine, foot controller, and standard bobbin case to the workshop. We provide comprehensive mechanical diagnostics before any bench work begins.
