Intro: K'nex Ball Machine Tartarus


Here it is after a year and a half!  My largest k'nex project to date; Tartarus!  It has over 31,000 pieces and touches my ceiling.  I started building in October 2010, and the final piece went in in January 2012.  I hope you enjoy!  Feel free to ask any questions you may have!

All I have to say is wow and nice job. how long does it take to cycle through the tracks?

Nice! So big! What are you building now?

I finished a much smaller project - but I'm not sure if I'm going to post it or not. We'll see :)

Otherwise, I have plans for another large project this summer, with a few restrictions that should make it really interesting. Similar to Metropolis, but obviously with different paths etc.

What is the "much smaller project"? Ball machine?

that little box thing where the ball only exits on the corner?
HOW DID YOU GET THAT TO WORK????????

Are you asking about that mechanism that runs it?

Alocke 11 years ago

It's actually pretty simple. The axle coming through the center is offset by an orange connector width. There are two axles that run perpendicular to the main axle that have wheels connected to them. These wheels run on small tracks which stop the whole table from spinning.

how do you make the maze thing tilt at 6:55

Whaoh, sorry this reply took so long! It's basically 4 offset axles, with each offset 90 degrees from the others. Go check out the circle ball machine someone else posted; it's basically an adaptation of that :)

Amazing! I tried to make something like your elevator lift, but I could never get it to work. Great job :)

Alocke 12 years ago

The elevator was one of the first things I built, but I didn't get it to work until about a week before the video was taken! I had a backup plan the entire time in case it never worked haha. But one day I just spent the day working on it and got it to work that night, so it's in the machine :)

And thank you! I'm really glad you like it!
