SETTING THE TIME ON A KEYWOUND CLOCK: (moving the hands) To set the time, move ONLY THE MINUTE HAND counter Clockwise (backwards) until hour and minute hand are at the correct time. (See figure 6). DO NOT MOVE THE HOUR HAND WHEN SETTING THE TIME. The hour hand will move automatically when the minute hand is moved. By moving the minute hand counter Clockwise it is not necessary to wait for the Mantel Clock to chime as the minute hand passes each quarter hour. (See figure 6). The movement has a self correcting feature which synchronizes the chimes with the time. If after setting the Mantel Clock on time, it does not chime properly, permit it to operate 2 hours to correct itself. You may move the minute hand clockwise to set the chime, but you must pause at every quarter hour and let the chime complete before moving the hand to the next quarter hour.

More food for thought Anons. While trying to go back to basics on Q's use of clock referenced, I decided to go way back to the use of words used like wind the clock, which suggest an old type of clock- perhaps one the like the navies may have used in the past?

But in doing so, I have been thinking- that for every position of the HOUR hand, there is a corresponding position for the MINUTE hand. Every Clockfag should obtain an old-fashioned clock that they can move the minute hand around until the hour hand is pointing at the position of the "date" they are investigating.

This might be worthy of investigating.

"HOW TO WIND AN ANTIQUE CLOCK

Although the concept seems fairly simple, the actual winding of a clock can be quite confusing. This is because there are different types of clocks and some can have more than one winding point. Most clocks will have one, two, or three winding points. Some clocks are wound using a key or crank, while others are wound by pulling on a chain. Although there are many different kinds of clocks, they can be broken down into several different categories according to how they are wound. This tutorial will explain how to wind the following clocks:

Antique British dial clocks

Antique grandfather clocks

Modern grandfather clocks

CLOCK WINDING BACKGROUND INFORMATION

Clock Winding Key In general, the number of winding points correlates to the total number of gear sets. When there is only one winding point, the movement will only have one set of gears. When there are three winding points, there will be three gear sets within the movement.

To determine how many winding points your clock has, look at the clock dial and count the holes where a key can be inserted. Please refer to the picture below showing a dial with three winding points. The reason clocks have multiple gear sets is so a clock can chime on the hour and quarter hour while it keeps time.

All clocks require at least one set of gears dedicated to keeping time. Clocks with two and three gear sets will be able to chime on the hour and quarter hour respectively. Additionally, most clocks are set to run for eight days, before having to be wound. It's always a good idea to wind them every seven days. By winding every seven days you prevent the clock from stopping."

My fellow Anons, once again, I am going back to basics. According the advice for winding old clocks above, they recommend winding a clock every SEVEN days. Think there could be anything to that?

Also wanted to say that for 60 possible MINUTE positions of a full rotation, the HOUR hand can be found to have moved one position for every 12 minues.

To explain, for the non-producers,

From the 12'o'clock position, the MINUTE hand must move 12 minutes before the HOUR hand moves into the 1-second position in the clock. During the next 12 minutes, the HOUR hand will move from the 1second position to the 2-second position etc.

Along the lines of MINUTE hand correspondence to HOUR hand position, a chart can be made:

MInute hand @ 12mins = HOUR hand @ 1,11,21,31,41,51 secs

and @6,16,26,36,46,56 secs

Min. hand @ 24 mins = HOUR hand at 2,12,22,32,42,52 secs

and &7,17,27,37,47,57 secs

Min. hand @ 36 mins = HOUR hand @ 3,13,23,33,43,53 secs

and @8,18,28,38,48,58 secs

Min. hand @ 48 mins = HOUR hand @ 4,14,24,34,45,55 secs

and @9,19,29,39,49,59 secs

Min. hand @ 60 mins = HOUR hand @ 5,15,25,35,45,55 secs

and @ 10,20,30,40,50 60 secs
