QUESTION: Hi Michael,
I have a mantle clock with a Franz Hermle 141-070 movement. Since the clock was originally used on the set of a Soap Opera the strike hammers were removed so that the clock would remain relatively quiet. Any idea where I can fine a replacement?

ANSWER: Thanks for providing the photo. There is an easy way and a hard way to do this. Based on your photo it looks like someone cut the hammer wires instead of simply removing the hammers. Now the rods are too short to reach the bells. The wires are pressed into the round collets and those collets are pressed onto the shafts that go through the movement. The easy fix is to solder some more wire onto what is left of yours. I can give you more detail on that. I also can provide you with the hammers and wire.
The hard way requires you to get new hammer assembly (and I'm not sure one can be purchased). The movement would have to be disassembled to replace these. Please don't try this unless you know how to do it. The mainsprings must have their power let down before the movement can be taken apart.
Let me know if you want more detail on either option.

QUESTION: Sounds like the first option is the way to go. Can you give more info on that option?

Answer
I can sell you the hammers and some wire material. You (or someone else) would solder the new wire material to your hammer wires. The movement must be removed from the case.
The way to do attach the new wire to the old is to overlap the material by at least an inch. Some people wrap a thin wire around the two hammer wires to hold them together. You would use flux. Lay a piece of solder on top of the two wires you are soldering and heat from below. I would use a cigarette lighter but you can use a torch if desired. After you have the new material soldered to the old you can cut to the length you need to reach the bells. The new hammers go onto the wire and are held on with a small set screw. This allows for easy installation and adjustment of the new hammers.
If you are interested in purchasing the hammers and wire you can get my contact information from my website at:
