Introduction: Knex Simple Modified Stepper Lift

By My YouTube Channel
About: I like to build with K’NEX as you can find many things I’ve built here. I also love to watch YouTube videos, have played piano and drums for over 10 years, listen to music (not country), and play video games (…
This is a simple version of 39shadowman's Modified Stepper Lift orginally built by Thibaultisthebest. This one is a remake of speedydog550's stepper and has instructions. Wow! What a surprise! This lift is based on the original stepper lift that was in a Knex set, except it doesn't use as much friction when the carts have to slide on rods. Instead, the carts are on small towers that are attached to axles.

HERE'S the lift IN ACTION:

Step 1: The Base

Gathered your pieces for building with the newer black/white balls? Good, let's start out with something simple. Building the bottom of the whole structure. You NEED to look at all the pictures in every step even this one to be sure of everything. Right?

Step 2: The Dispenser Holder

This is what will hold the thing that will dispense the balls one by one.

Step 3: Layer 1

The first main layer of the structure. I have a lot of close-ups for this.

Step 4: Add a Entrance Track

Simply just add a yellow path to easily load balls one by one.

Step 5: The Dispenser

This is what will dispense the balls into the first claw when it lowers.

Step 6: Layer 2

The second main layer of the structure.

Step 7: Layer 3

Really simple, right?

Step 8: The Motor Section

This is were a crankshaft is motorized to rock back and forth a see-saw thing (which is in the next step) to work the lift.

Step 9: That See-Saw Thing

This is the important part that controls the lift rocking back and forth. Refer to the video to see how the whole lift mechanism works.

Step 10: Layer 4

The fourth main layer of the whole structure. Just remember what is showed in pic.2.

Step 11: Layer 5

Just another layer to the structure. The last main layer will be built in the next step.

Step 12: Layer 6

The top of the structure where the exit track will go.

Step 13: The Blue Supports

You're gonna need these to hold the claws on the axles just like the main layers do.

Step 14: The Exit Track

This is where the balls will exit from when a ball gets pushed off of the top claw.

Step 15: Building the Steppers

Now it's time to build the stuff that'll help transfer the balls to the top.

Step 16: Attaching the Steppers

Now to attach everything you built in the previous step. Be sure to look all the pictures to see how everything is attached.

Step 17: Motor Placement

Lastly (if your using a battery-powered motor like me), you're probably gonna need to put that red battery thing somewhere so your dog doesn't have it for lunch. lol

Step 18: You're Done!

Congratulations! You now have your own simple version of a modified stepper. Now, just load some NEWER balls into the dispenser, turn the red motor switch to the right, and let the fun begin! If it doesn't work, try putting new batteries in. If it still doesn't work, I don't know what else to say for you. If you really want to use the OLDER balls and it doesn't work, just try to modify it to the best of your ability. 

If you built this, send me a picture and I'll put it on this step.

Till next time
