Project Micro - a Mini K'nex Ball Machine by Son

(son's project from long ago) Project Micro is a small, desk-top ball machine that contains 2 trails; when adjusted correctly, the balls never fall off.

Unfortunately, I am way too lazy to sit there and count all the pieces. If you aren't, let me know. My guess is around 500 to 600.

I'm going to apologize in advance for the size of this step. I didn't feel like taking apart the drive shaft, etc. Make sure you look at the annotations for the last couple pictures.

This supports the whirlpool.

Just build what is in the pictures.

This holds both towers together and makes sure they don't fall over. Build what is in the first picture, then assemble what you've built so far (pictures 2 and 3).

This is the gear that supports the chain at the top.

Idk. Just build it and mount where shown.

This pushes the balls off the lift. Make sure it is centered.

I don't know what to call 'em. Just build them and attach.

This is additional support for the switch

This supports the switch itself and prevents the ball from falling off when switching

Give a General Description of the Step.

There is really nothing to write here.

Build what is in the first picture, then whats in the third picture, attach them, and mount.

Build the chain, then throw it on

Go for it.

This is the flashiest part of the machine. Make it; make sure it totals 720 degrees (two times around) and mount. Once you get to testing this trail, make sure it is consistent. It might take a while

This catches the balls after they come out of the whirlpool.

Make this. Be sure you have the spacing right. LOOK AT THE ANNOTATIONS ON THE SECOND PICTURE!

This feeds all the balls to the lift.

Build this and slide on where shown.

Build these two rails and connect where shown.

Decides between the two paths.

Self explanatory.

...

Yay

Put these on. This will stop the ball from falling off, and, as a bonus, the ball makes a very satisfying plunk when it falls in.

Build this, put it on, and leave it, for now.

Build this, then put it on.

Add the balls, and you are done. Those crappy loopin' lizard balls work fine even though they are lighter and slightly bigger. You will probably have to adjust a couple things to make it work.
Enjoy your mini ball machine!
