Antique Mantel Clock Gear Train Overhaul and Cleaning

The clock is a spring-driven mechanical mantel clock, roughly seventy years old, that has been running fast, striking the wrong hour, and stopping within a few hours of a full wind. The movement has never been serviced and the mainspring barrel is coated in old, hardened lubricant that has turned into a gummy varnish. I need a full mechanical restoration of the gear train, not just an oiling.

Scope of work: remove the movement from the case, disassemble the plates completely, and pull every wheel, pinion, and arbor for inspection. Check each pivot for wear grooves and out-of-round bushings — I suspect at least two worn pivot holes in the third wheel and escape wheel bridge based on the wobble I can see when the mainspring is under tension. Ultrasonic clean all brass plates, wheels, and the barrel in a proper watchmaker's solution, then rinse and dry thoroughly before any parts go back together.

The escapement needs real attention: the pallet fork looks slightly bent, and the beat is noticeably uneven — you can hear the tick-tock favoring one side. Reset the beat, check pallet stone angles, and true up the escape wheel if it is not running flat. Re-bush any worn pivot holes rather than just re-oiling them, since papering over worn holes only buys a few months before the wobble comes back.

Once the train is clean and true, reassemble with correct-grade clock oil at each pivot and a light grease on the mainspring itself, then regulate the pendulum for accurate timekeeping and correct strike sequence on the hour and half-hour. The case veneer is in decent shape and does not need touching — this project is strictly the movement and gear train. I can provide close-up photos of the movement and a short video of the current ticking pattern on request. Looking for someone who has actually serviced spring-driven striking clocks before, not just quartz replacements.
