Bendy Spiral | a K'nex Ball Machine Element
Intro: Bendy Spiral | a K'nex Ball Machine Element
Hello! Here is the final element from my k'nex ball machine 3XODUS. It is a spiral but doesn't use any tubing. This was a big challenge as I had to get the shape and steepness correct or the ball wouldn't roll down! I have made many improvements to it since it was on my ball machine. It is very well supported now. Remember that this is a very heavy element so make sure it is extremely well supported in your ball machine or it will fall off! Want to build it? Let's go!

Anywhere that the ball gets stuck, put this under the track that is having that problem. Over time, the element should sort itself out. Some places you may have to modify yourself.
