Knex Ball machine Twister - TGKTR3 Entry - Now with video! Answered


I finally finished my ball machine. Its by far my biggest build, eating thousands of pieces and many hours. I'm happy with the result though. It features a few larger elements, such as the "Yin Yang" as seen on KI, a switching element made of ball switchers, a large spiral bowl, a big arm dropper and a 2 stage element. All together it comes to over 90 feet of track!

The other main part of this ball machine is the lift mechanism, called "switchers" (I think...)
They are really cool. One of the drawbacks is that they require a fair bit of energy to work, so I had to gear my motors down t have enough torque. So its a bit slow, but I think its well worth it.

But enough of my biased intro, have a look for yourself!

Oh yeah, and thanks to The knex weasel, darth trainman, shadowman39, I used their ideas in this ball machine. Also thanks to Gortess, whom I borrowed a few pieces from.

Other cool facts...
Took a month and a bit to build
Took 2 hours to take apart
Uses 7000 pieces
Has over 90 feet of track!


The video has arrived! Sorry for the wait. Hope you enjoy it.

Here's the direct link.

I had to repost the video on a different account, so your comments/ratings are gone now, sorry. For anyone interested, there was 400 views when I took it down.


Cheers! ..And do as you wish :-p

If you were to build one like the labyrinth, you probably could, with it going around your house.

by th eway did you make wipe out just so you could make a video of it and are you working on a new ball machine

in that case the video was really bad becuase he did not take a video of each path but the ball machine is really cool

Oh, okay. I don't know why I thought it had 25, lol.

9 Tracks? Thats gotta be a new record.

where did you find the halp looped tyhing with drop in the center i would like to add it to my current ball machine

Its an element I came up with... There are a few others though, search "Yin yang" on youtube to find a few.

the lifts are a bit slow but the ball machine is very cool

hey iac i saw a post on your orange borad and i can post on there so im posting here

but i was wording if your could help me(plz pm me and i will tell you)

and i just had to give you this

below is what you posted

Ive seen those videos far to many times... Go ahead and pm me. I just posted those to show someone on KI, I couldn't post them there for some reason,

what does pm mean and by the way u used a ball arm that was in project NAOANO

There's close ups in the photos here.

There's an instructable for the lift too.

Do you have a Photobucket account if you do can you give me a link??

I do, but there is nothing on there I want anyone to see apart from to photos I post here, so there is no reason.

 I am rating .5 stars untill you remove the keyword "gun" from the tags, when you remove it i will rate 5 stars like it deserves. I do not want to see this is the knex gun top rated page. Not cool.

This is a forum topic.  And there is no "knex gun top rated page".  There is just a top rated page.

I am rating all of your instructables .5 stars because you care about rating.

WOAH, this is AMAZING !!!!!!!! This is what knex should be used for, not bloomin gunz !!

Oh my god! I could just imagine that! Firing his heavy cannon at this at point blank...

Duck and cover!

I also had the idea of someone building both the heavy cannon and the knexsayer, and putting the knexsayer right in front of the barrel of heavy cannon, then having the heavy cannon firing right into its side.

Aww I wish I saw this comment earlier! I had both made and I took them apart piece by piece! =(
