    Hello, here is a video to know how to disassemble the shock absorbers, basically by pushing the two plastic parts inside and pulling the rod. Then you take the spring and put it on the axle.

    Hi Nico, how do we break down a shock absorber to make a button? at the end, are we just using the spring on the shock absorber with a new axle? Thanks!

    1/ panel 5×11 ref 64782
    2/ spring : use spring from lego shock absorbers (grey one)
    3/ push hutton : down : 3941 up : 2654
    All this items are in the bill of material and on rebrickable 🙂

    I have a question on 3 items:
    1) # of item on img_3360
    2) # of item of the spring and the pushbutton on img_3343

    Thanks for your help,

    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 😀
