Hey everyone,

Here are instructions for my best working Knex Ball Separator to date. It's not too difficult to build, no motors are needed and works about 90% of the time when instructions are carefully followed.

You can check out step 1 for the special pieces that you'll need to build this separator. Also 11 Medium yellow (or grey) and 7 small bleu (or brown) gears are needed. If you don't have 11 Med yellow gears, don't worry, you can replace the 7 Med gears in step 9 and 10 with the Med red gears instead.

In step 19 you'll see that a little table needs to be made and fixed underneath the separator. This table puts the separator at an angle of 12 degrees, which is very important! So if you want to use this separator in one of your machines, make sure it stands at an angle of 12 degrees.

You can always watch the video to see how it works.

If there are any complains, problems or questions, feel free to pm me or tell me in the comments below.

Thanks for watching, building,

Thibault Art

btw: Sorry for my bad english, I'm working on it :).

Step 1: Special Pieces You Need:

You'll need 2 of these.

Step 12: Very Important Step:

Make sure that all 7 grey connectors attached to the yellow rods are exactly in this position.

Step 13: Another Imprtant Step:

A little bit of space between every grey and oranje connector is highly recommended.

Step 18: Third Important Step:

Make sure that there is 1 red connector going up and 1 down everytime you turn the octagonal wheel. If all 7 red connectors went up and down 1 time after the octagon did 1 complete spin, Congratulations! You placed every single gear perfectly :).

Step 20: Go Ahead and Try It Out!

Step 21: Little Detail:

It's possible that the ball jumps over a red connector. If this is the case, elevate the track just a tiny little bit untill the ball doesn't jump over the connectors anymore.

<p>are you going to make the first one in the vid?</p>
<p>Yes, I'll try to make instructions this weekend.</p>
<p>ok thx</p>
<p>still gonna make it???</p>
<p>I'm very sorry for the massive delay. It's coming this weekend without any dought.</p>
<p>ok thx its nothin :)</p>
<p>Sorry for not posting the smaller separator yet. Things got in my way, but its coming soon.</p>
<p>How does it reset the red connectors?</p>
<p>There is no reset system, When the wheel makes one complete spin it just starts over again. Just like my previous separator that was featured in my Ball Machine Exception you know. </p><p>If you really want to find out, you'll have to build it :).</p>
<p>I made it! and installing it on my ball machine</p>
<p>Thats Awesome, I hope it works well!</p>
<p>great it work's good</p>
<p>Thanks fo building! Were the instructions easy to follow?</p>
hi there, the instrutions were will set out and easy to follow thank's for that,
<p>starting on your sparator now, cant wait to incorperate it in my machine!(12k pieces)</p>
<p>Thanks! I hope the instructions are easy to follow. 12k? wow, looks like a big machine is coming soon. can't wait :).</p>
<p>'Here a Little Teaser of my build, only part of the framing (core) and fast networks arde done here, still need loads of framwork and elements, including your seperator!. this is a couple of weeks back, i like to keep it a bit of a suprise!</p>
<p>This is great! I might make this if it would have a parts count.</p>
<p>Thanks! yeah, I never make a list with all the pieces. Sorry for that.</p>
Awesome work!! What's your next instructable?
<p>Thanks! Next instructable will be another lift, and after that the second separator you see in the video.</p>
