Introduction: Knex Micro Rollerball Lift

Picture of Knex Micro Rollerball Lift
This is a remake of my first ball lift: the micro rollerball lift. My previous ball lift almost gained no height.

This is made to be customized at the car entrance, car exit, motor attachment, ball exit, or the entire thing could be customized; just follow the steps but ignore the pictures.

Great for collabs with people who like knex rollercoasters.

Step 1: What You'll Make

You'll make these, but can easily be customized.

Step 2: The Scaffold

The scaffold raised at a 45 degree angle at most.

Step 3: Addition to Scaffold

If you're following the pictures you would notice the scaffold can't hold up now, so this piece will hold it up until you decide something better.

Step 4: The Bottom Gear

Something needs to hold the chain: the gear. Make sure it almost touches the track if you're making a custom version.

Step 5: Top Gear

Picture of Top Gear

If your scaffold is a micro red rod across then the axle for the top gear should look like this. The motor gets attached onto the black rod.

Step 6: Connecting Track Pieces

These few pieces will attach the track on.

Step 7: Bonus Bit to Hold Back Track

This is to curve the track back on itself. Don't add if you're making your own custom version.

Step 8: Adding the Track

Get some track and connect it. If you're following the pictures and struggle to get the track on, look closely at the track connections and align it by that.

Step 9: The Chain

Picture of The Chain

The car needs a chain to pull it up. Use 102 links if you're following the pictures.

Step 10: Support Sides

These will stop the ball from falling off the sides until they reached the top.

Step 11: Entrance and Exit Track

Picture of Entrance and Exit Track

The entrance track is a path leading to a rod which is high enough to let the car under, but low enough to stop the ball going under. The exit track is like that too, except at an angle so the ball gets pushed off.

Step 12: Adding the Entrance and Exit Track

If you're making a custom version, you would've made the previous step on the lift to the description, so skip this.

Step 13: Done!

Now to add anything else custom to it, such as the rollercoaster track, motor, and enhance the exit track.

Nice, but I hate micro K'nex.. I'm sorry.. /:

mathsboy314 (author)dickheijboer2013-07-09

Me too, but I really want to make the rollerball lift.

dickheijboer (author)mathsboy3142013-07-09

Hmmm, I got no micro K'nex.. :D

It will still work with normal K'nex, but you will need to improvise....just make a normal diagonal lift and add sides to the track as shown in this Instructable....

Sure it can!

This is a great idea!...I have made a ball machine and roller coaster that intertwine with each other, but this gives it a whole new way of working together!!
