    Hi William, I was looking at your youtube channel, this machine is really cool. Why was this machine split in half temporarily?

    Thanks. By the way, this instructables page is shared by me and my brother. :) The machine fell apart in a few places because of support issues, so we split it in half and put it back together with more support. In the process, it became a lot better than it was before it broke. ;)

    Cool I wish my machines were big enough to even have support issues!

    Could you possibly tell me more about the contests? eg how often they do them how to enter

    well, they started it in 2013 in July through August (here's the link). Then they kept doing the same contest in 2014 (here's the link). Then they did it in 2015, but they did it at a weird time last year. They did it in March, so we weren't able to add our finished ball machine into it (we would have if they had kept it at the original time, we would have. Here's the link) I sure hope they do the contest this year, because we have a few projects waiting in line, so I will be upset if they don't.

    I hope this helps you! Look forward to seeing new instructables from you!

    Oh, here's a link to the upcoming contests! (it hasn't been updated in a while.)


    Thanks! I really really hope they keep doing the contests too!

    We will be coming out with instructions soon. In fact, they are done but just waiting for the contest this year. But if you want to you can try to recreate it and make instructions. Just remember to give us credit, ok?

    great i finish it now, i just need to post instruction and when you say that you are going to make instruction, it is elements of this machine ??

    if you still want to try to make instructions, feel free to.

    just the elements. :) That's great that you managed to rebuild it!
