Introduction: Knex 'Slider' Ball Lift

Picture of Knex 'Slider' Ball Lift
This ball machine lift is piece efficient (according to me) and is a bit like the 'alternator' lift, but on it's side.

It is also easily modified to get higher.


Step 1: Making a Scaffold

Picture of Making a Scaffold

This scaffold will be made of 'cubes' and a slope down the side.

Part of the scaffold is left out, on the black rods around that there are dark grey connectors.
There is also a small ramp at the orange connectors, a yellow connector at the top, and extra base at the bottom, front.

Step 2: Moving Part

This bit slides up and down.

Step 3: Adding That

Clip these onto the dark grey connectors in the gap.

Step 4: Parts of the Top Side

These next for bits combine to get the full top side.

Make 1 of the first part, 5 of the second part, six of the third part, and ten of the fourth part.

Step 5: Connecting the First 3 Parts of the Previous Step

For each of the third part, clip it onto either the first or second part.

Step 6: Assembling the Top Bit

Now put those pieces together. The blue rods should being pointing together.

Step 7: Entrance Pieces

Each piece is laid out to where they fit together.

Step 8: Assembling Entrance #1

Combine the red track with the short stick, strange shape, then yellow track.

Step 9: Assembling Entrance #2

Now add the sides and roof.

Step 10: Adding the Entrance

Easy addition!

Well almost. Just make sure that you count 6 connections.

Step 11: Motor Parts

There it a large motor, a crankshaft, and 2 grey rods.

Step 12: Putting the Motor Bits Together

As it shows.

Step 13: Add That, and You're Done!

Clip it on at 5 connections (don't forget the crankshaft to slider connection), and you're done!


That was easy (or at least, to me).

I made this. It works very well. I like the way it pushes the balls up. I made a video of it lifting up 3 balls at a time. It handled them quite well.

Neat lift, I like the fact that it uses waaaaay fewer pieces than Shadowman's Alternator Lift (which always kept me from building one). Although the movement appeared in the video to be slightly delayed with more balls, I consider this a well-crafted lift. Great job!

Don't worry about the jumpy movement. I've edited it to remove that in step 4 (see tags)

Ohhhh...Nice! :-D

would it work if I made it bigger

Awesome lift!

Works very good, I'll use it in my next ball machine.
It took me only half an hour to build.

If I ever build another ball machine I will try this lift. thanks

Very ingenious! I like how the balls can enter from any point.

I like this lift, simple and piece efficient.
