• Upcoming updates
    Over the next couple of weeks we will be performing software updates on the forum. These will be completed in small steps as we upgrade individual software addons. You might occasionally see a maintenance message that will last a few minutes at most.

    If we anticipate an update will take more than a few minutes, we'll put up a notice with estimated time.

    Thank you!

    Atmos Help Please

    The bellows are indeed interchangeable. I swapped them out, and my other clock’s bellows were able to wind the clock in our normal home temperature. The bellows are actually influenced mostly by temperature changes and a very small amount by barometric pressure.

    Yes, the issue was that the spring was fully compressed (and immovable by the bellows) at our homes ambient temperature. I’m trying to think of a good way to explain the mechanics of it to you … So as you said, gas is compressible, but steel, not so easily. Once that thick counterbalance...

    That depends on if the friend that I repaired the clock for keeps his place above 72 degrees or not. If he keeps his home cooler than we do (which I think he does), then there won’t be a pressing need.

    That idea would work for a weakened bellows, but would be counterproductive for a weakened spring. The mass (thickness) of the spring material pressed together is what stops the bellows when the spring is weak. This means that once the bellows has fully compressed the spring, it can go no...

    Thank you all for your responses. I did find the reason why the clock wasn’t winding. An older post on this forum gave me the clue which lead to the solution. So it turns out that the optimal operating temperatures for Atmos clocks is from the lower 50 degrees to the lower 70 degrees (f)...

    Atmos screws

    I actually, just yesterday, broke a movement mounting screw on an Atmos, with the threaded portion remaining in the plate. My first observation was that the screw on my Atmos wasn’t brass, it was actually a plated iron or steel. I was able to remove the threaded portion from the plate by using a...

    Atmos Help Please

    Sir, I’m actually very near sea level here in south-east Georgia. Around 100 feet elevation. As for bellow’s health, all I could go by is measurement of the bellows’ cavity in various temperatures. It will go completely flat when placed in the freezer and then extend to within 22 to 25mm of...

    Yes, it does. It will wind effortlessly if I press and release the coil spring manually.

    Atmos Help Please

    Yes sir. Full disassembly, thorough cleaning of the spring, and all pivots, pivot holes and jewels; lubrication of the mainspring and first two (non-jeweled) arbor pivots with Moebius D3, and reassembled making recommended adjustments.

    I just remembered that there is a separate message board for Atmos and 400 day clocks. Would an admin be able to please move my post to that board?

    Atmos Help Please

    Atmos help please: A bit more than 6 months ago, I repaired and serviced an Atmos that had been in pretty rough shape. I got everything cleaned, serviced and adjusted according to the Atmos repair notes and the DVD instructions by Gerald Jaeger. It immediately started running like it should and...
