Chime Cylinder

[ticktock]

On an 8 hammer chime cyclinder which hammers are the first four notes of the Westminster Chime? How are the hammers numbered e.g. the hammer at the back plate is number 8 or 1?. I do not have gongs to check it out.

Thanks and Happy Memorial Day

We need more information. The first quarter of a Westminster chime sequence is a four note descending scale. Which hammers are used could depend on the manufacturer and age of the unit.

It is a Hermle 32316. Does this help?

That no. might mean something to MARK, but to most of us, we look for a sequence of two sets of nos. separated by a hyphen: like 1051-850, 1151-030, 1161-050 - nos. like that.
Now, even without knowing that, you simply look for FOUR pins arranged sequentially on the drum. Regardless of the number of rows, your Westminster will use only FOUR of those rows. When you identify those four sequential pins, you've identified the first quarter chime of your Westminster. Arrangement of hammers - which first: Allowing the pin drum to rotate under power will tell you rod arrangement by direction of drum travel - which hammer is lifted first.

Scottie has a good plan. Just be aware that the same four note sequence also occurs at the end of the 3/4 hour chime. You have a 50/50 chance so play it through one hour and if you are getting the four note sequential run at both the 1/4 and 3/4 you've got it :0)

Sounds good Scottie and thanks Shutterbug.

Erm, SB, it is the same four (or 8) notes - the chime barrel (drum) rotates twice in an hour, so there is only one descending scale on the barrel.

AFAIK most if not all chiming clocks use the hammers and rods in order, no problem to time it even with no rods present.
If this is a dual chime, it is better to time it on the Whittington chime - same descending sequence on 1/4 and last peal of 3/4.

Why have you no rods? Interested!

True enough, but you still have to have it in the right place in relation to the cam

Ticktock, 32316 is an Urgos number for a grandfather movement. Put it to the Westminister setting and see which 4 hammers are being used.

Scottie I think I have it. The same 4 hammers strike on both the first quarter hour and at the end of the 3/4 hour chime. Now the striking hammers for these notes are not "in line" meaning 1,2,3,4, or 8,7,6,5 but more like 7,3,2,4.
Is that ok? I don't have a gong setup in the shop to test it.
