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 <strong>wow</strong> 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 :) <br> <br>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 &quot;much smaller project&quot;? Ball machine?
that little box thing where the ball only exits on the corner? <br>HOW DID YOU GET THAT TO WORK????????
Are you asking about that mechanism that runs it?
yes!! <br>:D
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 :)
really cool ball machine!
Amazing! I tried to make something like your elevator lift, but I could never get it to work. Great job :)
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 :)<br><br>And thank you! I'm really glad you like it!
What was the backup-plan? ;)
Just a chain lift hahahaha
Oh, lol xD
31,000 pieces??!! That is all my pieces combined! You're amazing!
Thank you! I want more hahah
Incredible!!!!! So many pieces!
Thanks! :)
Do you have pictures from the elevator lift for me, so I can update the Official Guide to Ball Machine Elements?
I don't have instruction pictures for it, but I can find some pictures of it in the machine if you'd like?
If you have them, that's great! Instructions are not needed for the Guide, however it might be handy to have a picture showing the lift :P
screenie of the vid.....I could do it, to me it's just a matter of a few min<br>
*Lifts. The Elements one is dead :P
this is so nice !!!!!!!!!!!!!!! cooooool
This is an awesome ball machine! Great work on this one. I'm looking forward to your next project as well. ;-)
Holy. Your fingers must be sore. Nice work though it really payed off.<br>
i can't stop watching it xd it's soooo cool ;)
Why isn't this featured?
Probably because I don't have pictures :/
but some other videos are also featured...
Once again, Amazing mate! A lot of people are gonna use this one for inspiration!
Me for example xD
I subscribed. Can you tell me? :p
Nope! :D<br>But on the plus side, this project shouldn't take me nearly as long to complete. The only thing really holding me back from it is I can't start it for another four weeks, due to some stuff, and I'm a junior in engineering school, so my life will get crazy here in a month and a half or so. However, once summer starts it shouldn't take more than a few weeks to make this thing :D
Cool build! What do you have planned next?
You'll just have to subscribe and find out! :D
This is amazing. Possibly better than cataclysm?
Wow thank you! Cataclysm and Wipe Out were the machines that inspired me to actually do this, so to have someone compare it to those is such an honor!<br>
Thats just to awesome! Like I said in the video I love that switch!
That is just sooooooooooo cool! great work!
