    Hi Daniel,

    you will get a lot of results if you google \”wig melding\” or \”tig melding\”. There are also a lot of youtube videos available.
    By means of an electrical arc you produce enough heat to meld materials like stainless steel. An inert gas like Argon protects the weld puddle and asures a high quality stainless connection.

    Regards, Robert

    otherwise, the electricity would focus a lot on the head of the screw, because it is so close.

    I thought as much 😉

    I use plumber\’s goop or household goop.

    Thank you for that information. You know, this kind of glue is hard to get in Europe. But it\’s a minor problem for me because I\’m often to Canada or the US respectively, so I will buy one there at my visit next week. 🙂

    I normally keep it assembled for cleaning.
    i fill the cell up and empty it out 3 times with decent water, and then let it drip dry for an hour, and then refill it with my good charged water.

    That\’s perfect. Because in this case I thought up a simple suggestion for improvement. In order to detour the forces from the core to the inner sphere, I will fix the 2 halves of the inner sphere together by means of my inverter melding machine. 3 dots should be sufficient and in case of – it will be possible to disassemble the sphere without major damage.

    Daniel, some other questions:

    • what ist the plastic cap of the bolt for? Mine is much too big, so it does not snap on the electrical connection bolt of the outer sphere.
    • which kind of goop do you use? I looked it up and found several diffenent types of goop
    • is it necessary to disassemble MoeJoe completely sometimes e.g. for cleaning purpose? If it is, how often should this be done?

    yes, i do have an objection, although i\’d like to first day i appreciate your good thought.
    it is an excellent thought for the physical solidness and robustness of the cell. however, with one rod, the very centre of the cell, the very very centre, would be
    iron, and we want a diamagnetic material to be present there.

    Ok, I understand. So what do you think about this idea? It should fulfill all requirements, is robust and has the Bismuth core in the very very center anyway. B)

    Hi Daniel,

    first of all thank you for your immediate reply, I really appreciate your support!

    Ok, I\’ll try to repair the core.
    In my opinion the Bismuth core with its 2 threaded rods is more or less MoeJoe\’s backbone. For that reason it should be robust to a certain degree. The weak point is that your construction has 2 rods. Why don\’t you use just 1 longer through going threaded rod and fix the Bismuth core in the middle of that rod? This way the Bismuth would not be stressed by any torque or any other force and it is also located exactly in MoeJoe\’s center. Do you raise any objection to such a repair?

    Best regards, Robert.
