Setting a Grandfather Clock

1. Tips to setting a grandfather clock

by fine-tune the bob on the pendulum: That circular metal disk at the base of the rod is known as a pendulum bob.

This nut situated on the base on the bob is employed to modify the grandfather clocks running speed. Should the bob be lifted , the clock should probably increase its speed, when put at a lower postion, then the clock is going to go more slowly.

You'll be able to keep this principle in mind, using the expression


Assume a precision that is at least one minute, slow or fast each week. Begin by setting a grandfather clock to a precise electrical or even quartz timepiece .

Compare the time on both clocks a day afterwards. Should the clock run too fast, move the nut left ( facing the clock) also the bob should be moved lower, this will slow the clock. However , when the clock is too slow, move the actual nut right, that will move the bob upwards, the clock will move faster.

Go on by setting a grandfather clock on the right time . Have an itemized report regarding the length that you move the nut every day and also the subsequent minutes off. Do that every single day til you have come within one minute of the right time. After that, change to verifying the grandfather clock exactly each seven days, employing the same procedure until finally the clock keeps the time around a single minute each week.

Grandfather clock restore tip: A lot of grandfather clocks have been made in order that a single complete turn with the nut on the pendulum is equal to one minute each day. Which means that, for instance, in case your grandfather clock happens to be two minutes fast inside a twenty-four hour interval, turn the nut two complete turns left.

Remember that this particular principle will not be accurate for all tallcase clocks.

And, please remember, mechanical timepieces are certainly not as precise as present day electrical or modern quartz clocks!

Whenever you adjust the pendulum on the grandfather clock, you're trying to get best timekeeping achievable with a mechanical clock in between regular weekly windings. When you wind your grandfather clock weight every week, it's a smart idea to turn it into a exercise also to set the minute hand on the precise time as as it shows on any quartz timepiece in the home.

2. Check your grandfather clock to see if it has 2 nuts connected to the pendulum rod.

A number of grandfather clocks have not just 1 but 2 nuts at the base on the pendulum rod.

In case your grandfather clock features 2 nuts, the chances are you possess a truly precise grandfather clock!

Quite a few owners of such clocks assume that the lower nut is needed being a "secure" nut for the the upper nut. This is not true!

Grandfather clock restorer top-secret: Ensure the lower nut does not get into contact with the upper nut. Move the upper nut up or move the pendulum bob down till the best time is secured.

After that, through turning right or left, use the weight of this very nut for a more precise adjustment to setting a grandfather clock.
