An 8-day clock is a kind of grandfather clock that needs to be wound once every week, with an extension of one day in case you forget to wind it exactly after seven days for some reason. These are usually important pieces that can be passed from one generation to another as a type of family heirloom. These grow in value as precious items sold in antique stores as time goes by.
These clocks, unlike the modern day clocks, these do not work with the use of batteries or electricity, but with a spring, much like a music box. You have to be sure how to wind your 8-day clocks so that you will not have to set them again and again. You may ask your parents, if you inherited your clock, or you can ask a clock expert if you purchased it from an antique store. Here are some basic steps on how to wind an 8-day clock.
Know the parts of your clock. Clocks have the usual hour, minute and second hands that can be set according to the time you desire. 8-day clocks have additional features like winding mechanisms or holes that can be used with keys. These holes are for strike and time weights. Some have an additional hole for the chimes. Some have attached and some have detached keys. Be sure to keep your detachable keys where these cannot be reached by children and where you will not forget.
You can get a replacement for your winding key if this is lost or destroyed. Some clock experts can make a replica of your lost or destroyed key or may refer you to a clock shop that sells this kind of key. Be sure also that you will not use a winding key that shows any sign of damage. You will never know when it will snap out and hurt your fingers.
Using your winding key - Be sure that the winding key that you are using fits perfectly the winding hole so that you will not find any difficulty in winding your clocks. The 8-day winding clocks usually wind clockwise, but some are wound otherwise. An indication that you are winding towards the wrong direction is when you will not be able to wind it at all.
You have to turn your keys slowly but surely. This is to ensure that you will not break your key and you will not destroy the clock as well, since these clocks are usually cased in wood, whether mahogany, oak or pine. Pay attention that the sound made by the teeth of the clock's ratchet wheel. You are done winding your clock if the ratchet will already be locked in, the sound of the teeth stops or there is a complete resistance.
Winding an 8-day clock, as simple as it is, should be done in a correct manner. This is done so that you will lengthen the lifespan of your old grandfather clock and you will also be able to pass it on to the next generation.
