Knex Ball Machine: Revolution, Elements

About: Hey! I'm Sandroknexmaster. I like building with knex, especially ball machines. I live in Belgium. I speak Dutch, but also English and French. I hope you like my stuff, and like always comment, rate &...


Here are the instructions for the 5 new elements from my knex ball machine Revolution.

Not as many as usually, but the reason is that Revolution isn't as big as some of my previous machines.

If you have any questions, you can always post a comment or PM me.

Thanks for watching / building!


Step 1: Side Exit Arm

An arm where the ball exits to the side.

Step 2: Lift Arm

A cool element where the ball gets lifted up a bit after the arm is pushed down. This element works better when the arm is slightly tilted to the left, as seen in the last picture of this step. Make sure the ball enters slowly, or it won't work.

Step 3: Zig Zag Drop

This started as a lift idea but ended up as an element :D

Step 4: Clicking Path

Nice alternative path.

Step 5: Double Cross Tie Path

The parts under the path may seem pointless, but without them the ball gets stuck between the edges of the cross ties. And of course we don't want that to happen.

    Just realised the new path I made for my new ball machine is basically the same as one on here xD

    Love these elements. You always bring new things to the world of knex. I'll be sure to use some in my ball machine. (Like the clicking path.)

    Here's the picture you wanted of the clicking path! I'll also give you a video so you can see what the clicking path does in my ball machine, that is, if the video will EVER FINISH UPLOADING! :0


    I'm actually not sure how much I have. I have quite a few pieces, but not nearly as much as Sandroknexmaster does. ;)

    Yay! Finally got it to upload. This is just to show you what the path is and how I used the clicking path. It works very well! (The path, that is.) Sorry about the background noise; I have to build this in my basement and I think the water heater was running when I filmed this.

    Hm... This the video only plays when you're using a computer. Also, do you know if the element at the end is new? I'm pretty sure it is, but I thought that you might know.

    Thanks! It's nice to know that that's a new element. I actually made it because my other new element didn't work. I can't work on the ball machine for a week, or publish my new instructable for another week. Oh well.

    It's not bad at all, cause I'm on vacation! My guess for the contest is no, unless I really work on it because I still have 5paths to do. But I do have another entry that I'll post when I get back!
