The Triple-S Clock Mainspring Winder
User safety is paramount. Unlike more traditional designs, this winder operates vertically and the spring is enclosed within an open safety cage formed by carefully located pillars. All mainsprings, whether new or old, can fracture when wound. By enclosing the spring in a safety zone, risk of personal injury is significantly reduced. Most traditional winders operate with the spring coiled in front of the operator's face, and human error, component failure or spring fracture can result in serious injuries.Strength
Constructed from heavy gauge steel on a thick plywood base, very powerful clock and gramophone springs can be wound with ease. No plastic handles, knobs or levers. No flimsy click springs.Simple design
Deliberately designed to avoid expensive and delicate components wherever possible, this winder is so simply constructed it can be purchased in kit form or even as plans. The kit version now means that a mainspring winder is within reach of almost every repairer and enthusiast.
- Winds and unwinds left and right handed hole end and loop end springs as well as gramophone springs with hub centres.
- Fits and removes springs from barrels up to 70mm in diameter, 55mm wide and up to 0.70mm thick.
- Over 20 sizes of optional retaining barrels are available. Unlike most retaining barrels, the winder uses 'open' retainer rings that can be fitted and removed while the spring is still in the winder.
