Step 25: Tiny Wheel Lift

First featured in Citadel, this lift is the smallest a wheel lift can get, so small that it doesn't really resemble a wheel. It uses these small wheels and has them stacked up. The larger wheel lifts use a track with two rods/strands of tubing, but this one uses one. With the way I have it built it uses two medium yellow gears, so it isn't very ideal to make it very tall unless you use chain or different gearing. This lift is best when it's a red rod to two red rods tall, and it fits in small spaces nicely.

Currently, this lift is in my ball machine Citadel, which is still under construction. Click here for the update video that shows this lift working. The picture above is from Citadel's construction album.
<p>I had an idea for a lift, but not the time. It is a high powered motor in the middle and it is essentially a long tube on the outside. It picks the ball up on the bottom and uses centrifugal force to push the ball to the side. Not only does it bring the ball up, but it gives it a kick at the end for a little jump element. If someone wants to try and build this, feel free.</p>
<p>This is a very interesting idea. I think I might try it.</p><p>Could you explain your design in a bit more detail please?</p>
This would require a lot of structure. There would be a few diagonal shafts coming from a base. They would lean outwards, and as the base with the shafts spin the ball would be able to rise up the shafts and be launched out at the top. Loading the ball might be hard as well as making the area to cach them. If you have any ideas, let me know.
<p>So do you mean a combination of these?</p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/x_lz-B3bmsE" width="500"></iframe></p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/JTtLqa5rIRM" width="500"></iframe></p>
Not really. You know the tubes used in some K'NEX ball machines? There would be 4 of those on an 80 degree angle. They would be closer together at the bottom. The whole lift would spin.feel free to ask anymore questions.
<p>The guide has finally been updated, I would have replied to everyone's comments but Instructables won't let me...</p>
<p>Hooray, more lifts! :-) Thanks for updating this guide!</p>
<p>Amazing guide! Very useful and informative. The next time I need a lift for my ball machine, I will come here.</p>
<p>Thanks, I'm glad you find it useful!</p>
<p>You're welcome! :-)</p>
<p>A new lift I made about 2 years ago but forgot to put on here I guess its just another variation of a wheel lift....</p><p><a href="http://www.instructables.com/id/Knex-Slanted-Wheel-Lift/" rel="nofollow">http://www.instructables.com/id/Knex-Slanted-Wheel...</a></p><p>I also made another lift thats a variation on the slider lift except its vertical (basically an alternator lift) I'll attach some pictures </p>
<p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/hNHSGusXFWA Link to the slanted wheel lift video" width="500"></iframe></p><p>Link to slanted wheel lift video</p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/KPkiiKTaGjU" width="500"></iframe></p><p>Link to vertical slider lift video</p>
<p>Nice, the sliding movement is really smooth!</p>
<p>Here are a few new lifts: <a href="http://www.instructables.com/id/Spinning-Push-Lift-a-Knex-Ball-Machine-Lift/">http://www.instructables.com/id/Spinning-Push-Lift-a-Knex-Ball-Machine-Lift/</a></p><p><a href="http://www.instructables.com/id/Versatile-Chainsaw-Lift-a-Knex-Ball-Machine-Lift/">http://www.instructables.com/id/Versatile-Chainsaw-Lift-a-Knex-Ball-Machine-Lift/</a></p><p><a href="http://www.instructables.com/id/Short-Start-Arm-Lift-a-Knex-Ball-Machine-Lift/">http://www.instructables.com/id/Short-Start-Arm-Lift-a-Knex-Ball-Machine-Lift/</a></p>
<p>A new lift!</p><p>http://www.instructables.com/id/Sliding-Arm-Lift-a-knex-ball-machine-lift/</p>
<p>Sure wish he would actually add the new ones to the guide I wonder what happened</p>
<p>Yeah me too, he's just not that much into knex anymore I guess.</p>
<p>bummer</p>
<p>We'd reach 86 lifts if we include the ones from <a href="http://knexflux.net" rel="nofollow">knexflux</a>.</p>
<p>New Lift!</p><p>Double Jigsaw Lift! </p><p><a href="http://knexflux.net/instructions/double-jigsaw-lift/">http://knexflux.net/instructions/double-jigsaw-lif...</a></p>
<p>Cool lift! It looks to me like the time saved by making two jigsaws has an unwanted side effect of requiring gears to slow down the lift. Then again, complexity is admired.</p><p>Also, did you create the website?</p>
<p>Thank you! The extra gearing wouldn't be necessary if using a 12V motor which I actually highly recommend on this one :P</p><p>As to Knex Flux, it uses the SMF forum software with a custom theme made by me and the instructions engine is also 100% self-written, also featuring things like importing instructions from instructables!</p><p>Overall we (That is, the admins) created that site to have a dedicated website for all knexers to unite, thus any feature requests for it, no matter how big or small, are always welcome. And OFC we hope for the site to take off, you could do your part and join + contribute to it! :D</p>
<p>Also, I posted about it here: <a href="http://www.instructables.com/community/General-purpose-Knex-forum/">http://www.instructables.com/community/General-pur...</a></p>
<p>I'm working on making a hand for the end of an arm lift. Here's my progress: </p><p><a href="https://www.youtube.com/watch?v=Szd0svTT-e4" rel="nofollow">https://www.youtube.com/watch?v=Szd0svTT-e4</a></p><p>It's currently no so reliable and swings a lot. The height increase is so small it's practically an element.</p><p>I'm about to enter my final year of high school, so I probably wont have time to make this a worthwhile lift. Feel free (open to all) to use this concept and take the credit.</p>
<p>Another new lift!</p><p>http://www.instructables.com/id/Tube-Claw-Lift-a-knex-ball-machine-lift/</p>
<p>New lift!</p><p>http://www.instructables.com/id/Ferris-Wheel-Lift-a-knex-ball-machine-lift/</p>
<p>I built this lift... I used orange track clips instead of the gray connectors on the blue rods on the helix... the balls go up much smoother.. awesome design.</p>
<p>That sounds like a nice addition, thanks for building!</p>
<p>correction ... oops.. I meant white rods... getting color blind in my old age.</p>

<p>I was too late O_O</p>
<p>New lift:</p><p>http://www.instructables.com/id/EQVP22RHVS19501/</p>
<p>Added!</p>
<p>For some reason, whenever I try to make a lift other than a chain lift, it DOESN'T WORK. And I am getting VERY bored of chain lifts.</p>
<p>Have you tried helix lifts or arm lifts? There are many choices, so at least one of them will have to work for you. I agree that chain lifts get boring, haha.</p>
would it be possible to set the connected arm lift at a 45 degree angle?
<p>Reaching 45 degrees would be difficult due to the formation of the ball holders in relation to the arms. Looking back on the multiple arm lift (step 30, my design) I think it is geometrically impossible to achieve 45 degrees or higher while keeping all arms the same size and shape, and keeping the parallel-like pattern.</p><p>You could ditch the parallel-like pattern and try something like the Right-Handed Arm lift (step 31), as it has consistently designed arms, then you could modify it to 45 degrees, but this complicates the gear system.</p>
Yeah, you're right, I've been trying for days now and not much progress. It's impossible to get the arms to tilt enough to tip the ball onto the next one.
<p>I had the same problem when trying to make a staircase of Small Rotating Arm Lifts (Step 17). I should probably try a smaller angle...</p>
<p>some new lifts in here: </p><p>https://www.youtube.com/watch?v=zBZBZ7akolc</p>
<p>There was ACTUALLY instructions posted for the stepper lift before Retrograde:</p><a href="http://www.instructables.com/id/Knex_Inverter_lift/" rel="nofollow">Link</a>
<p>I think those instructions are incomplete.</p>
<p>I know this is a late reply, but I actually did use that link for the main structure (though never could find it after!) The problem was that it mentioned nothing about entrance and exit paths or the crank mechanism at the top. Those all had to be improvised...thanks again to <a href="http://www.instructables.com/member/knexpert%2310829476/" rel="nofollow" style="font-size: 15.0px;">knexpert#10829476</a> for making better instructions of the Stepper lift from my Retrograde pictures. :-)</p>
Too bad bezempje deleted his account and ibles :-( This look like a cool lift/shooter.I'm gonna try to build this from the pics, if I succeed I will post an ible on it...
I'm sure people will be glad to see an Ible of this. :-)
YAY!!!!! I rebuilt it perfectly!! :-D One Q - What height do you think this should reach? At the moment I seem to get 1 metre + in height.... but I have like 4 rubber bands on the end and the motor does not have enough torque so I am yet still tinkering around. I have also modified some parts of the shooter. <br> <br>I can post if you would like, let me know and i'll begin a Ible if so. :-)
