Putting A Mainspring in the Barrel
By ARTHUR DES ]ARLAIS
When all the spring is in the barrel except the brace end, by holding the end an instant, it will be drawn in of its own accord when sufficient coils are wound in towards the center to make room for it. As the spring uncoils in the barrel, it will firmly anchor itself. It would be well to practice this method several times using an old barrel and mainspring until proficiency is attained, when it will be found superior to any mainspring winder as it works equally well on all sizes, and most important of all, the arbor always fits the spring correctly. The writer has been using this method for several years with satisfactory results, and it has reduced mainspring breakage to the minimum.
