Jump Lift, a Knex Ball Machine Lift

Introduction: Jump Lift, a Knex Ball Machine Lift

About: Hey! I'm Sandroknexmaster. I like building with knex, especially ball machines. I live in Belgium. I speak Dutch, but also English and French. I hope you like my stuff, and like always comment, rate &...
Hello knexers!

This is the last of 4 new lifts all first seen in my knex ball machine Paradox.
It's a small lift that was used to lift the balls from the low white floor to the high white floor, but you can use it like you want.

You can make this lift stronger by adding more than 1 rubber band, and it also depends on wich rubber band you're using.
That's the reason why I didn't make an exit for this lift: The height and distance of the balls will be different for everyone.

If you build this lift, read every image note! It will help you a lot!
If you have any problems or questions, feel free to comment or PM me.

I hope you like it and have fun with building!

Very nice for how little pieces it uses.


I really like this lift! So small and piece efficient! Here are the pictures that you asked for on my instructable. The first picture is of the lift itself, and the second picture is where the balls are thrown to. It's the white floor that's in the picture. The lift is in my ball machine called legacy, which is the one I said was coming soon. :P


I love this lift! It has probably the lowest piece count of any lift (disregarding chain lift), is most compact, and has the simplest yet most amusing function. How could any ball machine builder resist? ;-D
P.S.: You can tell I like it, right? :-)

Nice! If only it could achieve cartoon height, like six feet of vertical. That would be awesome! This is a great lift as is.

For the six feet of height, I'd say add a lot of rubber bands and a 12v motor, but I don't think this design is strong enough for that ;)
