    Hi folks,

    So now that i have a little bit of experience with my cardboard designes i wanted to max out the concept.
    And 50 hours of cutting, glueing together and wrapping in tape this is what came out.

    I am a little bit proud i have to admit :rolleyes: (i really like the black and white look)

    Ps: could anyone tell me where to get a chrony (or a similar product)?
    maybe i am just to stupid, but i could only find american sites and the
    shipping would be very expensive.
    I really would like to know how fast these marbles are :)

    impressive weapon for cardboard!

    you spent a lot of time making it, but at least it's not as noisy as working on wood and makes much less sawdust. ;)


    maybe you could get even more power out of it? how long did you cut the bands and how far do they stretch?

    So, now i have done some test shoots with Chrono connect. (nice app!)

    i was shooting a glas marble which weights about 6 grams.
    Of course i don´t know how accurate this app is but i get steady results
    between 85-90 m/s and 21 - 25 Jouls.

    unfortunately i didn´t have more rubber (but it´s already ordered).
    It can easily take twice as much draw weight, so i hope for even better results, i will keep you informed.

    Wow! And those results I think are pretty darn good for a marble shooter!

    Very well done, Mr Cardboard Master :D

    That is some helpfull information.
    Honestly, to this point i was always just concentrated on the weapon itself and when it was finished i just cut off some rubber which seemed to be the right lenght and put it on. (no thoughts put into the rubberlenght etc.)
    i know, it´s not quite the most effective way ;), but now i will start calculating beforehand.
    Thank you very much, it´s so nice to get this kind of feedback!

    Great job again!! You have every reason to be proud, that is a lot of hours spent slicing cardboard and gluing!
    Great video, as well. It looked like your cat really was enjoying your curtains too:D

    Honestly i think hey were just playing with each other, but maybe i am wrong.
    Considering how often i was woken up by them, because they broke a lamp or something, i think it´s fair to scare them once *jk*:D




    Thank you very much.
