## What causes a grandfather clock to run slow?

If you turn the nut as to lower the “bob”, the clock will run slower.

## What do you do when your grandfather clock is slow?

## How do I make my clock run faster?

To slow down the clock, loosen the adjustment nut (turn it toward your left). The bob will settle lower, making the effective length of the pendulum longer. The clock will run slower. To speed up the clock, tighten the nut (turn it toward your right).

## What causes a pendulum to slow down and stop swinging?

When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) slows it down and eventually stops it.

## How can I make a pendulum clock run faster?

The clock can be made to go faster or slower by means of the nut at the bottom of the pendulum. Turning the front of the nut to the right speeds up the clock, and turning it to the left slows it down (in other words move the nut up to speed up, or down to slow down). Turn the nut only a small amount each time.

## Should the weights on a grandfather clock drop evenly?

Yes, the order is critical for proper function. On 99% of floor clocks (grandfather/grandmother) with three weights, the heavier weight goes on the right-hand chain hook or pulley as you are FACING the clock.

## How do you fix a slow wall clock?

To remedy this, simply take down the clock, open up the battery compartment, and inspect the batteries to see if the batteries are worn out or rusted in any way.

## Why does my clock run fast?

3 Answers. These types of clocks usually keep time by counting mains cycles rather than using any sort of internal timer chip. So, if your mains frequency is too high, they will run fast. The fact that two clocks are running similarly fast is another clue that this may be the case.

## How do you hang weights on a Grandfather Clock?

## How do you change the speed of a mantle clock?

To slow the clock, move the lever down towards the “-” (minus). To speed the clock up, move the lever up towards the “+” (plus). A small change will make a quantum change in the speed of the clock.

## How do I reset my Grandfather Clock?
