Are there any clock makers or experts on here.

[Rudi McAnichal]

I inherited a “Napoleon Hat” chiming clock that had probably not been running for at least 60 years. I took out the chimes and movement, then cleaned and lubricated the accessible bearings (with proper horological oil). The clock now keeps perfect time and chimes correctly (selectable Westminster/Whittington).

Unfortunately the two springs for the chimes need to be re-wound every second day (they can only be wound about half a turn). These are fully-enclosed springs, and I am guessing that they are clogged up inside. The main clock spring only needs winding once a week.

I don’t feel competent to fully dismantle the entire mechanism, and a professional repair would almost certainly cost far more than the clock is worth. Is there any way to clean that type of spring in-situ by flushing out the gunge?

Just remember there is tremendous power in the coiled springs.
When you buy new ones, they come bound with wire.

i cant believe they still sell the part I need!

You can get a surprising selection of clock type bits, I've improvised a suspension with bent wire on occasion but best to get the pukka part
The clock oil looks just the job too

I've cleaned out enclosed springs, to a degree, also by the petrol bath method, they've usually got a kind of vent or drain hole on the casing, quite a bit of crap can come out.
