Introduction: Bendy Spiral | a K'nex Ball Machine Element

Difficulty: Very Hard

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!
