Knex Ball Machine Lithium W/ Instructions




Introduction: Knex Ball Machine Lithium W/ Instructions

About: Hi, I'm KneXtreme. I'm a Christian and I'm home schooled. I love to build with almost anything especially knex. I also do Taekwondo and collect coins. Just so you know, I don't hang around youtube ...
               Introducing my ball machine Lithium. It has 2 lifts including Keggore1's car lift and ChassisDude98's Quarter Arm Lift. I have modified Keggore's car so that it can work on the thin and thick roller coaster track. If you want your car to have better grip than use the thick roller coaster track, but if you want it to turn easier use the thin roller coaster track. The angle I used is the steepest possible angle the car can climb.
              Lithium also has 6 tracks and 6 new elements. It also contains martb95's spiral panel stairs. All of the new elements (including martb95's spiral panel stairs) will be posted on my guide plus a few extras. So be sure to check it out.
              Lithium is the biggest project I've ever made instructions for, so if you have a question or are confused about something please leave a comment. If you like it please vote for it in the Toy Contest. Enjoy the video.  p.s. The first song is by me.

Step 2: Building the Track

The track is what the cars will run on. The bottom turns are the ones that don't have the grey rod, the top ones do.

Step 3: Building the Support Towers

The support towers will... uh... support the track. First you will build the left one. Then the right. And finally the middle.

Step 4: Attaching the Support Towers and Track

Step 5: Building and Attaching the Base

Step 6: Building the Quarter Arm Lift

This lift was originally built by CassisDude98. I just modified it a little.

Step 7: Building the Support Tower and Loading Mechanism

My ball loader is a bit different then Keggore1's.

Step 8: Building the Ball Loader, Main Paving, and Basket Lifter

Step 9: The Left Side

Both the left and right side contain 3 levels.

Step 10: The Right Side

The right side is almost the same as the left.

Step 11: Extra Supports

Just a couple extra supports.

Step 12: The Top

Step 13: The Tunnel

The green tunnel part is not a necessity. It just makes it look cool.

Step 14: Track 1

Step 15: Track 2

Step 16: Track 3

Step 17: Track 4

Step 18: Tracks 5 and 6

Step 19: Attaching the Roller Coaster Tubing

You can use thick or thin roller coaster track. You may have to trim it a little shorter once you put it on.

Step 20: Building the Cars

You can build as many cars as you want. If your using the older boxier motors make sure you take off the battery covers and put some tape around it so the batteries won't fall out.

Step 21: All Done!

Congratulations! Now that your all done throw some balls in it and have fun watching the cars pick them up and take them up the hill.
Remember to check my guide out for those new elements. Hope everything was clear enough.

I don't have enough pieces to make this, but I think that this is the best knex ball machine on instructables with instructions. Congrats on winning in the toy contest!

Hi! I'm excited and getting through building this. I would like a closer look at the lifting arm please, I don't know what's off the screen to the left of this picture. Or did I miss it?


Reply 6 years ago on Step 6

Huh? That's odd. I guess I forgot about that. Do any of these help?


My only gripe with this is I already took that name once:

Otherwise, great ball machine.
