Step 2: Frame Side One


Just follow the pics and pay attention on image notes.

Step 3: Frame Side Two


Now you'll make the second side of the frame. Again, read image notes. !!!!-Important-!!!!! don't put the frames together after this step!

Step 4: Sorter Part 1


Again, read the image notes.

Step 5: Sorter Part 2


Again, read image notes!

Step 6: Sorter Ceiling


Again, read image notes.

First picture: 15 blue rods and 30 yellow connectores, there are two next to each other. In between each yellow connector is a green rod (It gave an error when trying to type that as image note).

Step 7: Putting Things Together


...not much left! Soon it will be easy for you to sort your rods! :)

I wish I had this when I got the pieces to make it.

Ahh...should've built this before spending hours sorting the new k'nex I bought before making my ball machine xD

It is actually quicker to sort manually than with this thing :P It's more like a proof-of-concept :)

you might have a new follower on twitter, just maybe....

looks nice :) it is going to be a tall one eh? :)

No idea, havent tried. But then again, try to fit multiple rods in there at the same time.
My guess is that it would work as it has no moving parts.

I think it would unless you have say a white rod on top of a red one. Then they would both come out the same hole.

No, if you look at the different size holes you'll realize that it does actually work. Well, it did at least for me ^^

I'm wondering if it would be faster to just sort them by hand? Instead of sending them down the chute. It's more fun to send them down the chute though. :D

Yeah, it would probable be a lot faster.

This is more a proof-of-concept than anything else ;)

Very good idea! I think making a lower piece count would be good (as in how many pieces are needed to build). I only watched the video but it seems very good.
