This tool is used to wind the [[Mainspring|mainspring]] of a watch so that it can be safely inserted into the [[Barrel|barrel]].

This style of mainspring winder is no longer widely available for purchase. The example above features three interchangeable drums to accommodate [[Barrel|barrels]] of various diameters. The [[Arbor|arbor]] is not interchangeable.

== How to Use the Mainspring Winder ==

[[Image:Vise-held-mainspring-winder-closeup-drums.JPG|thumb|320px|right|A close-up of the interchangeable drums in which the mainspring can be wound]]
To use the mainspring winder, the base of tool must first be clamped tightly in a [[Tooling/Vise|vise]]. Affix the inner coil of the [[Mainspring|mainspring]] to be wound onto the hooked [[Arbor|arbor]] of the tool. Wind the crank until the [[Mainspring|mainspring]] has been wound entirely into the drum. Place the drum, with wound [[Mainspring|mainspring]], as deeply into the [[Barrel|barrel]] as it will go. Pull the drum backwards, allowing the bottom of the drum (which is mobile) to push the [[Mainspring|mainspring]] into the [[Barrel|barrel]].
