Grandfather Clock Does Not Chime At Proper Time
Posted on May 11, 2015 | By clockde | 27 responses
If your grandfather clock is not striking exactly on the hour and the deviation is less than 15 minutes, you may adjust the minute hand to get it as close as you wish to an exact hour strike. You may have to do this several times to get it right as it is a trial and error method. As soon as you tighten the hand nut, it may change.
GRANDFATHER CLOCK DOES NOT CHIME AT PROPER TIME
If the Grandfather Clock chimes more than one minute before or after the proper time, How to Adjust the Chime Time on your grandfather clock? The minute hand should be removed and adjusted.
CAUTION: When performing this operation be careful not to scratch the hand nut, hand or dial.
1. When the Grandfather Clock starts to chime, stop the pendulum and record the time.
2. Using pliers, carefully remove the small nut that holds the minute hand in place by turning the nut counter Clockwise while at the same time hold the minute hand with your fingers near the small nut.
3. Remove the hand from the hand shaft by grasping it with your fingers at the point where it attaches to the shaft. Pull the hand straight off. This hand is not screwed on and should come off easily. The minute hand has a small raised area on the back side directly around the shaft hole, this is the hand bushing. Using
pliers, grip the bushing firmly by its sides so that it cannot slip in the pliers. With your other hand, turn the Grandfather Clock hand forward or backward the distance necessary to chime at the correct time. (See figure 20).
4. Re-attach the hand to the shaft and turn the hand nut finger tight. Make sure the hand points to the correct location that you recorded in Step 1 plus any corrections you made in step 3. If the hand does not point to the correct mark, repeat steps 2 and 3.
5. Snug up the hand nut with the pliers. Do not over tighten.
6. Start pendulum.
7. Re-set the time by moving ONLY THE MINUTE HAND counter Clockwise (backward) as described in Step 5 of the set-up operation.
EXAMPLE: Grandfather Clock chimes at 1:10 but should chime at 1:15.
Step 1: When Grandfather Clock chimes at 1:10 stop the pendulum and record the time of 1:10.
Step 2: Carefully remove the small nut.
Step 3: Remove the minute hand. Grip the bushing by its sides and turn the hand forward 5 minutes.
Step 4: Reattach the hand so it points to 1:15. Attach the hand nut finger tight.
Step:5 Snug up the hand nut.
Step 6: Start pendulum.
Step 7: Reset Grandfather Clock to the current time.
The following video will help to explain this process.
