Build a Mainspring Winder A mainspring winder is an essential tool for the clock repairer. Without one, a mainspring cannot be properly serviced. A mainspring cannot be removed from a barrel, nor can a mainspring be stretched out for the necessary inspection, cleaning and lubrication. However one major obstacle to obtaining a mainspring winder is its cost. Professionally made mainspring winders run anywhere from $200.00 to $350.00. The mainspring winder described in this book has a reversible locking ratchet mechanism which is essential for safe efficient operation of a mainspring winder. It can be made for around $25.00 dollars. It can be made just using simple hand tools and some store bought items. Or, if one has a lathe, some of the pieces can be home made. This book describes in painstaking detail with 17 line drawings and 7 black and white photos how you too can make your own mainspring winder and save big bucks. No shipping charges. No waiting for the mail. After payment, you can instantly download a PDF to your computer or Kindle. You can zoom in on photos and diagrams, translate, and print the PDF. Nothing comes in the mail. $4.99
