Introduction: Knex Chinatown Hill Ball Machine Instructions

Alright, it took a headache and a couple Advil but I finally got done with this ball machine. It uses ping pong balls and is very quiet when it is on. This design is a little different from its previous version but not much has changed. Have fun building this and wish me luck in the Knex contest:D


Step 1: Main Support and Lift

This is the largest piece in the ible. Carefully follow the pictures.

Step 2: Path Part 1

Here we go!

Step 3: Path Part 2

Let's continue!

Step 4: Path Part 3

Doing great!

Step 5: Path Part 4

Halfway there!

Step 6: Path Part 5

Almost there!

Step 7: Path Part 6

Home stretch!

Step 8: Let's Go Tubing!

Unfortunately, there is no easy way to put the tubing on. I would start from the top and work my way down to the bottom but take your time. I would buy tubing from which has two strips just long enough for this machine otherwise the length is around 30-32 feet long. When you get done, great job! Thank you for building!
