I wrote the following projects in the course of my work in clock and watch repair. The information in these projects was developed by me personally as I came across various problems and sought for solutions that I was unable to find elsewhere. Whether you are looking for information about antique clock repair, grandfather clock weights, stress corrosion cracking in brass, atmos clock repair, or what clock tools to buy, you came to the right place. The projects are offered in their complete form with additional files for downloading and printing as you wish. You can also download them as PDF files for future reference.

Be sure to visit my other website about collecting clocks and watches, with its large photo gallery of mechanical watch mechanisms.
