Introduction: 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.
Step 1: The Main Tower
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.
Step 2: The Secondary Tower
This supports the whirlpool.
Just build what is in the pictures.
Step 3: The Bridge
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).
Step 4: The Top Gear
This is the gear that supports the chain at the top.
Step 5: Untitled
Idk. Just build it and mount where shown.
Step 6: The "Pusher"
This pushes the balls off the lift. Make sure it is centered.
Step 7: These Things
I don't know what to call 'em. Just build them and attach.
Step 8: Not Named
This is additional support for the switch
Step 9: The Wall
This supports the switch itself and prevents the ball from falling off when switching
Step 10: The First Path
Give a General Description of the Step.
There is really nothing to write here.
Step 11: First Path Part II
Build what is in the first picture, then whats in the third picture, attach them, and mount.
Step 12: The Chain
Build the chain, then throw it on
Step 13: End of First Trail
Go for it.
Step 14: The Whirlpool
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
Step 15: The Catcher
This catches the balls after they come out of the whirlpool.
Step 16: It
Make this. Be sure you have the spacing right. LOOK AT THE ANNOTATIONS ON THE SECOND PICTURE!
Step 17: Collector Track
This feeds all the balls to the lift.
Step 18: Nameless
Build this and slide on where shown.
Step 19: Beginning of Second Trail
Build these two rails and connect where shown.
Step 20: The Switcher
Decides between the two paths.
Step 21: Guard Wall 1
Step 22: Guard Wall 2
Step 23: Guard Wall 3
Step 24: Red Rods
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.
Step 25: Tension Adjustment
Build this, put it on, and leave it, for now.
Step 26: The Chain
Build this, then put it on.
Step 27: Done!
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!
We have a be nice policy.
