    Hey, Nico,

    thanks! It works 😀
    It was in fact the rubber bands!

    Again: thanks.

    Hello, can you send me some picture of the overflow mechanism on my email, in order I can see it. I do not oil the mechanism, just set up correctly the mechanism. Is your digit works ? (carry mechanism). I assume that the rubber band of overflow mechanism is too tight which cause high force to release it. Try some smooth rubber band 🙂

    I have build your Mechanical Calculator full correctly, but the Overflow mechanism (powered by gravity) doesn´t work correctly, it doesn´t fall down like expected, so it doesn´t work at all.
    Do you have some tipps to fix the problems? Did you oil the mechanism?

    I´m every time really liking your buildings and have built one of the cars, the CVT, the two Planimeters and the helicopter ^^
    Id had some other problems with these, but I was able to fix them all by myself ;D

    But this time, I wasn´t able to find out the bug…

    I would be very happy if you had an idea 😀
