Picture of Knex Modified Stepper Lift
Hello everyone! It sure has been a long time since I made an Instructable.  This lift is based on the 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. So, you can make it as high as you want! This lift was originally built in my unfinished Knex ball machine (pictures below). Since then, I have improved it, and it works much better than the original. :-) Also, I decided I would make this lift in the Power Tower Crane/Lost Mines color scheme, mainly because I was out of yellow connectors at the time of starting it. :-P

Here is a video of the lift in action:

Note: This version does not work with newer Knex balls (from Motorized Madness, Big Air Ball Tower, etc). But, you could modify it to fit those types of balls.

I hope you like it!
Also, I thought I might mention about my inactivity. I haven't been building Knex for a year or active on any websites because I was playing Minecraft the whole time. :-P But now I'm back into Knex again, and I'm building a big project (not a ball machine) that I will keep as a surprise as usual. I'm excited about being active again! :-)

What is that knex tower in the background of picture 8? (Intro)
Shadowman39 (author)  Sorunome3 years ago
It's a lift I was building for a collab, but we gave up on it.
The one between you and rnb?
Shadowman39 (author)  Sorunome3 years ago
No, me Tornado and ALocke.
I never knew of that one D:
What was the error with multiple balls
Shadowman39 (author)  Orangeprofessor3 years ago
The balls wouldn't transfer from one side to the other due to its height, and the force that it took to push the balls out. That's why I modified it to this version.
In the previous version couldn't you have just a stronger motor or used a counterweight
Shadowman39 (author)  Orangeprofessor3 years ago
I don't think that would've helped. Each side was basically balanced anyway, since there were two sides that alternated.
So what was your way of fixing it
Shadowman39 (author)  Orangeprofessor3 years ago
Building it like this one. :-P

Picture seven looks like my room, messy.
Shadowman39 (author)  KneXtreme3 years ago
Messy rooms are da bomb! :-D I need to clean it up and vacuum, the rugs are growing hair it seems.
Absolutely! :) Luckily I have hard wood floors ( witch doesn't really help much) I've got dust bunnies running around all over the place :)
Shadowman39 (author)  KneXtreme3 years ago
Having three cats doesn't help with the hair issue haha.
If you think three cats is bad I have four and two dogs.
And bunnies
Thanks for reminding me. I forgot about the bunnies :)
