Why we offer only the complete chime-block

We now only offer the complete clock chime-block and rods. The rods are a press fit into the chime-block by machines and it is difficult to get a single rod out. Other times there are threads that go into the block but have such a secure tight fit, you cannot remove them.

Trying to do so would result in more rods breaking. Also there are various threads on the rods that are the replacements and it can create much confusion. It is for these reasons that we now offer the complete clock chime-block and rods.

Overall, it is a tricky thing to get the correct thread size for the individual rod in a chime-block and rod set and have it fit perfect. Not to mention, when the chime-block rod is not the correct size, often enough it gets sent back. Then we get into the situation of trying to swap it out over and over.

Moreover, all of it eventually ends up being a return for a complete chime-block and rods set. So, in the long run it is best to just get a new chime block and rod set from the beginning. That will save a lot of time and frustration.

Chime-block and rods volume

The volume of the clock chime is not alterable by means of the chime-block and rods or the hammer adjustment. These parts have nothing to do with making the clock louder or softer. The only thing that can make the clock louder or quieter is to move the clock case.

If the clock is on a hard wood surface it will be louder. A rug will be quieter. The proximity to the wall can also alter the sound. It has nothing to do with the chime-block and rods.

Clock Chime Block Styles

The first step in purchasing a new chime block is to determine the chime block style that is in the clock.

The Styles are side, bottom and back strike.

Figure out which style you need. Then, count how many rods are in the chime block. Measure through the chime block to get the length of the longest rod.

Correspondingly, find this information on the drop down list for the correct chime block and rods.

Bottom Strike Style A

Chime block style A For bottom strike and side strike units.  

Side Strike Style B

Chime block style B For side strike units. Occasionally, you can also use this for back strike diagonal Westminster units.

Back Strike Style C

Chime block style C is for floor clock models (and some wall clocks) with two rows of hammers on the back of the clock movement.

Chime sound in Clock Chime Block Styles

No matter which Clock Chime Block Style you need, there has to be some adjustments made. If the clock chime does not have a clear, crisp tone, do not panic. It could just be a matter of adjusting the hammers on the rods.

The hammer heads are on wires which are meant to be bent. Do this with your fingers, while the hammer head is down.

Just bend the wire that the hammer head is on, one at a time. Keep the hammer head about 1/8” from the rod when it’s at rest. In other words, in the up position. Bend one at a time.

Then, lift and drop it to see if there is a nice crisp tone. Subsequently, do this right down the line with each hammer on whatever chime block style. Make sure each one has a nice tone. In the long run, the chime will sound perfect.

Why does Chime Hammer Positioning Need to Occur

Mechanical clock chime hammer positioning is easy to do. It only involves bending the hammer head wires. Upon the initial installation, this was done by the clock maker as well.

When replacing a clock movement you need to bend the chime hammers to the chime rods. This is why the hammer heads are on bendable wires.

They are meant to be bent into the perfect position. It is not uncommon to bend them an inch this way or that way. The clock movement will not have the hammers in the perfect spot to make the correct sound when hitting the rods. This is why chime hammer positioning is so important.

Clock Chime Hammer Positioning

A mechanical clock movement has hammers that need to be bent into their final position. The correct clock-chime hammer position needs the tops of the hammer heads to be about 1/4 inch down from the chime block.

The hammers need to be 1/8 inch away from the rod. This would be when it is at rest. In other words, bend the hammer wires so the head is 1/8 away from the chime rod. This spacing between the head and the rod is so it will not thud or double strike.

Tuning the mechanical clock chime

Repeat this process for each wire, one hammer at a time, down the line. Continue in this manner until you can lift and drop the hammer to create a crisp sound. If each hammer head is done this way the clock will have a nice song in the end.

Often a customer will say the sound is not correct. This is due to improper hammer positioning. When performing the above directions correctly the sound is beautiful.

Positioning the 340 / 341 series

The 340 and 341 Hermle clock movement series went through a change in the hammer wires. The hammer heads were on wires, but now they are made on flat bars. The positioning is still the same, however it is a little more difficult to bend them.

The hammer head is on the skinny end of the bar. The bar gets wider as it goes back toward the roll pin.

With needle nose pliers, bend this bar where it goes from skinny to wide. The overall assembly will be slightly higher from the chime block. That is, if you are swapping out the movement with the older style wire hammer head rod.

It is an option to raise the entire chimeblock with a shim to help with this. It is not an absolute requirement. Bending the hammer arms are usually sufficient.

I recently purchased a Howard Miller 612-221 Jennison mechanical wall clock in like-new condition and had it shipped to me by a popular shipping company across the country. The clock was well-packed, double-boxed, and surrounded by lots of bubble wrap. The pendulum was removed, but the chime rods were not supported by any method.
 
After transit, there was no damage to the clock’s wood case, and the clock runs and chimes amazingly well while keeping accurate time. The only problem is that during unboxing, it was discovered that 3 of the 8 chime rods had broken during transit and were lying at the bottom of the case.
 
The clock’s movement is a relatively recent Hermle 1051-030 triple chime unit dated 2012 with a side-strike chime block and 8 rods, 14” the longest. The press-fit number 5, 6 and 7 rods were all broken at their press-fit base in the cast iron chime block. Fortunately for me, the chime block is easily removed on this model clock by removing only two screws.
 
I’m wondering whether Clockworks has ever seen this problem occur during clock shipment. I’ve had several other Howard Miller vintage mechanical clocks, both mantle and wall styles and some with less packing, shipped to me over long distances and never experienced this problem.

Hello, I have a Ridgeway clock with a Hermle movement 451-033 H recently purchased from Clockworks and installed by myself. I am experiencing a very flat note at the beginning and several other times throughout the Westminister sequence. The problematic chime rod is the shortest and located closest to the dial of the five chime rods.Do I need to replace the entire chime block? If so, please indicate the product that I must replace it with. Thank You.

I have an old St Charles school clock that needs new Westminster chime rods. It’s five rods with the longest rod over nine inches.
The movement is an Hermle 351-020 48cm/96.525. Do you have either the set of 5 rods or the rods with the mounting.

This one, in whatever length

The length of the rods do not matter so much, only the longer the rod the deeper the tone of the song

Does not matter really. The longer the rods the deeper the tone. Depends on what sound is wanted with the song

Hi,

What are the numbers off of the back plate of the clock movement itself? If it is hard to get to, usually you can stick a cell phone up behind the movement and get a picture of the numbers. Or through the side access panel if there is one.

I’m looking for a 5-rod Westminster, but the order of the rods in my 340-020 Hermle (Baldwin clock) is the reverse of that shown in the picture. In my chime block, the longest rod is furthest away from the mounting portion of the block. Can I order a chime block with this arrangement?

Can I replace a 5 rod side strike bimbam chime block with a westminster 5 rod chimeblock?

James Stoudenmire

The term bim bam would imply the chime block has 2 or sometimes 3 rods at most. So unsure of this question please rephrase

These are the only options for this style. Keep in mind the longer or shorter the rods only mean the deeper or higher tone only.
