 I made these pages as basic tech. help to others in the horological field and to give the public an idea of what it takes to do even the smallest repairs.  If anyone has any comments or something they would like to add to list please email me.  Many minds working together will accomplish much more than one working alone.  Please note that there are many ways to do different things in horology and I am not implying that any ideas in these pages are the best or only ways to do any given project.

I will be adding pages to this list on a regular basis so be sure to check back often.
