So I made my first ball machine...Subduction! (Subduction-a process dealing with tectonic plates sliding under each other) It has four paths. Anyway, it's not so great perhaps because my elements (those I had) aren't so original. But I did invent my own version of the wheel lift, and I designed a new pathing type I haven't seen yet. So, here goes...

Step 1: The Lift

This is the wheel lift...or is it an arm lift? At any rate, the balls come in through the bottom track, are whisked upward by the wheel, and deposited at the top. I made a "gate" of sorts to control ball flow, but it didn't work as well as hoped. And for those of you wondering, I have no Knex motors, so I have to make do with a crank. (If you build this, feel free to add a motor)
 
99% made:)

I like the slide in path 3. Can't wait to see your next ball machine (is it bigger?)
Thanks!
My next ball machine is taller, but as to bigger....I don't have millions of pieces like lots of people, so I pretty much use everything in each machine. But never fear, I added some more complicated elements to round 2.
You can buy a lot of random pieces on ebay for a good price
I know, I just haven't gotten around to that yet.
Cool! Can you make a vid?
Sorry, I don't have access to a video camera. :( But on my next ball machine, I may try a stop-motion animation. (Also I already broke it down awhile back. But I'm glad you like it!
Cool that's a good idea! I even think that nobody ever tried before to make a stopmotion of a ball machine...
And I like it because it's good, sure if you don't have many pieces. :)
This is cool! Even though it's not the biggest I like the different paths. 4.5* (.5 off for no video ;)
