    This could be one of the most valuable resources on the site, but it's hard to find (how about establishing a section on the website called "Resources" or "Quick Links" that would contain such basic information as this and include Timesavers and other suppliers' (ie, ones still in business) part numbers? This chart lists "LaRose" as a source in most cases, and LaRose has been out of business for some time now. On a related note, I find this particular site to be very confounding to navigate; it could be far simpler and still accomplish its goals.

    How about Encyclopedia? With clock repair as a sub-topic. Also you will find all the links in the Clock forum, Repair Hints, How-to's, Supplies and Services
