Introduction: Knex 'Slider' Ball Lift

Picture of Knex 'Slider' Ball Lift

This lift is quite like the 'alternator' lift, but at a 45 degree angle. It's also a lot more piece efficient.

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 is the bit that slides up and down.

Step 3: Adding That

Clip the previous step onto the dark grey connectors in the gap.

Step 4: Roof

This is the part that goes above the slider so the ball doesn't go down.

Step 5: Attaching the Roof

Attach each of the blue rods to the scaffold.

Step 6: Entrance Track

This is where the ball enters the lift

There are six places to connect the green rods.

There are five connections to make.

Put a spacer on any of the red rods like in the pictures.

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

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.
