Suspension Spring 12-Piece Assortment (timesavers.com)
I bought this assortment a while ago and have used several of the suspension springs to repair various German clocks. The replacement spring assembly doesn't have to be an exact match to the original as...
The original spring may be pressed in. If you have a lathe, you could try drilling a small diameter hole in the center bottom of the screw slot. Then a suitable diameter steel pin could be used as a drift to push out the remains of the original spring.
This might sound obvious, but I had an issue identical to yours on a T & S Gustav Becker with a rod gong.
Turns out the brass rod which connects the strike hammer to its pivot was barely contacting one of the movement holder posts, making a clacking sound as it struck. Re-contouring the rod...
Very cool, nice job!
What's the thread size?
Looks like you used aluminum flat bar, what dimensions?
Is that steel square tubing?
If you wouldn't mind posting a photo of your assembly next to a ruler it would be appreciated!
In your earlier post you state, " The chime barrel for the HH is hollow, while the H 1/2 movement's chime barrel is solid. "

Thanks for the info, it is appreciated! Sorry I missed your previous post, thanks for the link.

One annoyance, there seems to be no chime correction feature on this movement...
Recently finished overhauling this German Westminster chime clock. The movement has no manufacturer's markings I am aware of. I would appreciate any comments re. who manufactured this clock, and when.
