I have a Howard Miller wall clock that is about 25 years old. It still looks like a brand new clock. It currently has a Hermle 351-03A single chime movement which was cleaned and rebuilt a few years ago. While it is working fine, I am planning to replace the movement with a new Hermle triple chime movement (1051-030A) because I want the triple chimes and more importantly, the ability to turn off the chimes at night. My question is about chime blocks. My current chime block has 5 rods (longest length 12”) of what appears to be bronze (back mounted). They appear to be pressed-in and not screw-in. I don’t know for sure that the chime block was made by Hermle but I am assuming it is because the original movement is made by Hermle. Since my new movement will be 8 hammers instead of the current 5, I will need to replace my current chime block with an 8 rod block. My question is: should I get a chime block with steel rods or bronze ones as my current one has? My current bronze chimes sound great and since I am quite content with their sound, I am inclined to replace it with an 8 rod Hermle chime block with chime rods of the longest length I can possibly find (up to 14” that is since my case will accommodate that length). I’ve been told that the longest chime rods possible will produce the best sound. I guess that my questions at this point are: - Is it true that the longest length chime rods produce the best sound? - Is there any advantage to using steel rods instead of bronze ones? - I’ve seen in the literature where they recommend mounting the chime block so that the hammers strike the rods at 1” from the base in order to produce the best sound. The hammers strike my current rods at 1/4” from the base and as I mentioned earlier, they sound great. Should I mount the new block so that the hammers strike at 1” from the base as I’ve seen recommended (there is room in my case to do this), or should I just go ahead and mount them so that they strike at 1/4” from the base as in my current movement and chime block? - Finally, does anyone know where I can get a Hermle 8 rod bronze chime block with rods up to 12-14” in length (assuming that is my best option)? I have checked with Merritt and Black Forest Imports and neither one has Herme chime blocks with chime rods that are as long as I am looking for. Thanks in advance for any feedback.
