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! :-)
