Introduction: Knex ThatThing Ball Machine Instructions

Hey guys, this is my final ball machine for a while so I hope you enjoy it! If someone could tweak my design I would greatly appreciate it! I also decided to show you the crazy guy behind the curtain! Cheers!

P.S: This is the beta instructions, and a video will be posted soon.

Update 15-5-19: Added pictures of the original build from a while ago.

Update 15-5-19: Fixed fatal mistake with drive shaft for crane in step 1( added pictures of corrected shaft)

Update 21-5-19: Fixed fatal mistake with the connection with the claw and the drive shaft. Look for the annotation in step three.

Step 1: Base and Gears

Since this was sort of a Rushed instructable, you will be seeing chunks of things instead of pieces but you'll have more than enough views to make it. I also corrected a fatal mistake with the drive shaft. The first two pictures show the correct build of the shaft.

Step 2: Supports

Big step!

Step 3: The Claw!

Time for that new lift!

Step 4: Path 1

The bridge is 36 yellow rods long.

Step 5: Path 2

Almost done!

Step 6: Original Build Pictures

This machine was actually built 2 years ago and I used these pictures to copy it for the instructions. You can see some subtle differences like how it is geared differently for an electric motor which I omitted for convenience. If I could just see the connections from the crankshaft to the crane it would be working perfectly. Darn!

I like this better than those immensly big ball machines... Sure they are pretty awesome, but this is better available to more people as you don't need a ridicoulous amount of K'nex and still contains some paths.
I wonder how it looks when it's all moving ^^ And just one motor? Nice :D

Thanks! Yeah, Ballbuster was the biggest pain to make instructions on. Lately I've been trying to make smaller machines.

ahhh good ol ballbuster, im actually currently making it in my bedroom. Thanks Knexpert! You have some of the best knex instructions ive ever seen! No lie!

Is that you? O.o

Awesome! I'll be waiting for the video!

How do you start making ball machine instructions? I want to make instructions for mine but I don't know where to start! would anyone please help me?

I take pictures of the finished product, then write down the order of parts. I then take the ball machine apart in reverse order of the list and sort the parts to their steps. I then start putting the machine back together.

Oh OK :D Sadly I took it apart but soon I'll work on a new one! :D

you can also start with the machine, take a part away from the machine, take pictures of it and go on like that. that way you don't have to reassemble the machine and you have all the pictures for the instructable.
