In this video I evaluate my grandfather clock’s hammer mechanism to determine if I can correct for very poor sounding chimes caused by wore out leather pads on the gong hammers.
I will also show my clock test stand that lets me fully run, evaluate and service my clock mechanism on the bench.

Tubes(chime gongs) for my Howard Miller Grandfather Clock:
———
The strings that hang the tubes are heavy waxed string like very thick dental false.
The string holes are 0.355 inches from top
The hammers strike the tube just below the top edge by an 1/8 to 3/16 of an inch.
The tubes are brass and mine are chromed but I have seen these gongs as just lacquered brass as well.
The tubes are all the same dimensions with the exception of the length.
The tube wall thickness averages 0.04 inches.
The tube inner diameter averages 1.08 inches.
The tube outer diameter averages 1.12 inches.
There are 5 tubes (chime gongs) in my clock.

(I rate this eBook 3 stars out of 5)
It could have been a lot better more more details and photos but it was still very helpful read.
