Hello everyone! After 3 years, my ball machine Citadel is finally finished! This machine features around 50 new elements, 5 different lifts, and 2 new path separators that separate into 17 paths. It's also themed, with Knex men all over the place working on it, giving it a factory-type feel with catwalks and stairs. There are 3 total motors, one of which powers all 3 floor lifts. The actual time it took to build is one year, there was just a long break in between. All of the paths (except one) were built in 6 months, starting in December 2015. I hope you enjoy!

Here are the element instructions!

<p>Can you get me instructions for the elements at 1:25, 2:17, and 3:28? I know you are busy, but it would be much appreciated if you could get instructions or lots of pictures for them. I am going to make a medium sized ball machine and would love to have these in it. Thanks! </p>

<p>Are you making a knex ball machine out of those?</p>
<p>I won't make it with those, but yes, I am making a ball machine. The reason I won't use those is there wasn't very good pictures.</p>
<p>Ya. I got some too. They aern't very detailed but I still made them.</p>
<p>Alright, I sent you a PM with the links.</p>
How are the instructions for the elements/lifts coming along? Do you have an idea on when they would be posted? I've been trying to re-build the jigsaw lift with the pictures given on your Flickr page. I was able to figure out the design and of the lift, but I'm now struggling with motorizing it.
<p>They're going well, school takes up most of my time so it might be a while. I still have to get pictures for 14 elements and organize the instructions. For motorizing the jigsaw, you have to connect the top crank and bottom crank with a shaft, and attach the motor to that shaft (this part can be seen in the video).</p>
<p>I think this is one of the best knex ball machines. I love all the lifts especially the 4 ball one. </p>
<p>Thanks! I plan on making instructions of the vertical jigsaw and stair-arm lift.</p>
<p>Hi. Is it possible for you to do an instrucatable for the path separator and also for your lifts? especially the 4 ball lift shown at 0.50 seconds? looking at tackling my first custom ball machine and would love that lift at the heart of mine :) Understand your likely busy but would very much appreciate it if you can :) many thanks</p>
<p>I wasn't really thinking of doing instructions for those, as they use up a lot of pieces. Furthermore, someone made instructions of a twin elevator lift before I had the chance to post mine. I think it would be possible to rebuild the elevators and path separator from pictures though, since the concepts are simple. I will be eventually posting the other lifts, after the elements which I'm working on now.</p>
<p>When do you think you will be done with the new elements instructable? Thanks, KneXFAN200</p>
<p>Sometime near the beginning of next year. I'm not sure how long it will take but hopefully I can get most of it done before school starts.</p>
<p>Sorry to bug you again, but are you almost done with the element instructable? About how many more days till you finish it? The reason why I asked again is because I'm in the process of making a ball machine and want some of those elements on there, but I can't put them on because they don't have instructions. <em>I really wan't some of the elements on it! No rush though! Thanks, KneXFAN200</em></p>
<p>The full guide might take a while longer since I'm starting school soon. But, if you want to build any element in particular I could make the instructions of those elements first and send you a link to the pictures.</p>
<p>The element at 3:26 of the video, 4:13, 6:45, and 9:05. THANKS!!!</p>
<p>Alright, I sent you the links in a PM.</p>
<p>Awesome!!! I can't wait!!!! I loved ciradel sooooo much and really wanted to build the elements! Thank You!</p>
<p>Citadel, not Ciradel : )</p>
<p>Amazing it's incredible the time that you passed on it! </p><p>Great job, like everytime ;)</p><p>-Pro</p>
<p>Thanks!</p>
<p>Shadowman... Still waiting on those elements/lifts! (not in a negative way) </p><p>Good work by the way</p><p>-OfficialKNEXGUY</p>
<p>Sorry for taking so long, it just takes a while as I have to rebuild all of them for the instructions. Thanks though!</p>
<p>You know quite how many pieces there are yet?</p>
<p>No, the machine is still up.</p>
<p>You should totally post instructions to those elements.</p>
<p>I will, I've been busy with school lately.</p>
<p>Oh. My. Word. That's MASSIVE! </p>
<p>Thanks!</p>
<p>My jaw literally hit the floor upon looking at this. Truly ingenious and inspiring.</p>
<p>Thank you!</p>
<p>...and I felt my jaw breaking the wood flooring when I witnessed that green 'sector' at the bottom. This really has inspired me, Shadow.</p>
<p>Haha, I'm glad you like it, that part took a while to build.</p>
<p>Love the creativity, never seen anything like it!</p>
<p>OGM DIS IS DA BEST EXPLINATION OF PERPETUAL MOTION ON JUPITER!!!<br><br><br>No but seriously, outstanding job buddy! It's going to be hard for me to top this one haha Hope to see more :D</p>
<p>Haha, thanks Koolcoaster!</p>
<p>It's so beautiful. I almost got tears in my eyes. this looks SO cool!</p>
<p>Haha, thanks!</p>
<p>seriously, no joke, I really LOVE this one. The lifts, elements and everything just looks good together! I also like the Portal reference and the little guys everywhere :)</p>
<p>Great machine, worth the wait! Its overall look is just amazing, I don't know why but it touches my knex heart that, though a bit inactive the past months, still exists :)</p>
<p>Thanks Sandro! </p>
<p>Wow, I'm speechless, great work!</p>
<p>Thanks!</p>
Amazing!
<p>Thanks!</p>
<p>Excellent work, I knew you would finish it! It is more than worth the wait: with all the brand new element ideas and the theming, I am left speechless. (Beautiful use of hinges in this machine!) Citadel is a new pinnacle for ball machines. Thanks for going out of your way to make this machine almost completely new material, as it is a rarer treat these days. Glad to see you still have &quot;The Shadowman Touch&quot; as you continue to lead the Instructables community in ball machine innovation. :-)</p>
<p>Thanks MCM! I didn't know you were still around, how have you been?</p>
<p>Good! I've been around, though I haven't posted any new ball machines due to my first year of college keeping me occupied. I look around Instructables gleaning ideas for projects and seeing all the new gadgets. I intend to get more creations out there at some point, just taking it easy like you did for awhile. I'm just glad to see big time ball machiners still active.</p>
<p>Ah, I see, what are you studying in college?</p>
