Mercury pendulum tubes

Recommended Posts

I have a french four glass clock that has a mercury pendulum, I have noticed that the tubes where placed upside down I have placed them the right way up, how long does it take for the mercury to run to the bottom of the tubes because its not exactly free running stuff, I think it would be pointless trying to regulate the clock until it has is this correct ?

Are you sure its a real mercury pendulum?

I've heard of cheaper clocks having fake mercury pendulums, could it be the pendulum was taken apart and put together incorrectly with the pretend mercury parts upside down?

The whole point of mercury is it is liquid and flows freely as Old Hippy says

From what I see the clock is a genuine French Four Glass. Mercury can solidify only with extreme cold. Myself I have never come across these what I will call dummy type pendulums. It would probably be best to replace them. I don’t think here in the UK you can post mercury.

No I'm sure these are mercury its a very good quality french clock I dont think they are replacement mercury vials I may put them in some slightly warm water and see if that helps.

Thats the problem they only seem to be readily available in America and I think it would be illegal to try and import mercury via the postal service into England and they are also very expensive.

    • I would imagine decreased amplitude if applied to fourth or escape wheel, but i noticed hardly any difference with the 3rd wheel in most cases so i think thick oil would be the proper lubrication here in most cases. My question is  why would Seiko make the distinction between capped and uncapped jewels? Why on the same wheel apply thick oil on the uncapped end and thin oil on the capped end? Is there some rule against applying thick oil to capped jewels that I haven't heard about?
    • Just noticed that Mark Lovick uses thin oil (Moebius 9010) for the 3rd wheel in his ETA 2824-2 service video (@8:58). This goes against the recommendation of the ETA technical sheet for the 2824-2, but I believe he does so for a reason. If you read this Mark your comment would be appreciated! While on the topic; what would the effect of using a thick oil be when applied to a pivot where we'd usually apply a thin oil, such as the escape wheel?  
    • Good work. You don't need much. Pity suppliers don't sell it in tiny amounts. 
    • Just to update: I got about a tablespoon of shellac flakes from my BHI DLC assessor, and they work great. I just put a tiny chip of it on top of the pallet, heat it until it becomes semi-fluid and spread it to the right places with a sharpened oiler. Then heat a bit more so that it flows out nicely. I think one tablespoon will fix a lifetime of pallets.. All the other shellacs I have I'll use for cementing workpieces etc. Cheers!      Rob
    • I'm not sure how up to date that guide is. Pretty much every service manual I come across lubes 4th and escape with thin oil but 3rd with thick oil. Even Seiko agrees, showing thick oil being applied to the uncapped side of the 3rd wheel.
