Check the minuet hand and see if it has a brass bushing in it where it attaches to the arbor. If so remove it and insert a square tapered tool of some sort, and turn hand to line up. Don't bend the hand. The end of a rat tailed file will sometimes be the right size.

You might want to try and fix the problem yourself. If you're lucky, the minute (long pointer) may be inadvertently installed up-side-down. Some clocks hold the minute hand on with a threaded nut and cup washer. Others have a cross pin through a hole in the center arbor and the cupped washer. Most have a square hole in the minute hand that fits on the matching square of the arbor.

If you remove the minute hand, it's important to replace it with the same squares aligned even if you turn the hand up-side-down.

To explain better, most minute hands on striking and chime clocks have the hand made of blued steel and have a brass bushing with a square hole staked in place. The staked or peened fit of the bushing to the steel hand is very tight, although it can be forced to twist somewhat with care. Thus the precise position of the pointer will be exactly at the proper quarter on the dial when the striking train is unlocked and allowed to run.

If a new hand is installed, very often a slight adjustment is required to assure the strike train is unlocked precisely at the quarter. Experienced clockmakers usually find it most convenient to use the square end of a small file pushed into the square hole in the brass bushing of the hand, then carefully forcing the steel portion of the hand to rotate a few degrees. Then trying on the clock for more or less adjustment.

The technique is not for the faint-of-heart as the steel portion of the hand is easily broken. Some luck and skill are both required for this adjustment.

Hi Les,

Point of clarification please,as I am a neo-phyte,are you saying that there is an original fit of the minute hand on the post at point of intial construction/ manufacture,and even though both the post and hole are square,if you reposition the minute hand in any of the other three possible positions it will affect its position ( + or - )regarding the time for strike?

Thanks,

Bruce
