Introduction: Knex Multiple Arm Ball Machine Lift
Hi! Here are the instructions to the multiple arm lift.
Here's a video: http://www.youtube.com/watch?v=0IF4ZdzzzVs
This isn't the exact same as the video though, because I forgot to make the instructable when I made this.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: That Section There... ?
Nah, this has a name. This part holds the ball dispenser, I just can't summarise it into a title.
Step 2: Extra Safety to That Part
This section fits on top of what's been built so far.
It should give a clear view where the arm comes to.
Step 3: The Ball Dispenser
As the name explains.
Step 4: Adding the Dispenser
Again, self explanatory.
Step 5: Roll Into Dispenser Part 1
This section will hold the path coming into the dispenser.
Step 6: Roll Into Dispenser Part 2
Here's the actual track the ball goes on.
Step 7: Putting That Part Together
Here's the side bit attached to the dispensor bit with the path on it.
Step 8: Adding 4 Red Rods
Just get 4 red rods and add them like in the picture.
Step 9: The Real Part Beggins!
It's just a hexagonal prism, only with a bumper at the front. I'll stress it in the picture.Y
Step 10: Adding It In
This fits in to the four red rods. All together it didn't fit into the picture, so that's why it's split into 2 steps.
Step 11: Layer 1
Layer 1 excluding the main base. There should be a missing blue rod (that's where the lower arm comes).
Step 12: Sticking It On
Now stick that layer to the rest of the lift.
Step 13: Layer 2
Now the second layer. This time there are 2 missing red rods. They get in the way of the crankshaft.
You might realise extra parts sticking out, they're to hold the motor.
Step 14: Adding the Second Layer.
The bit on the side should help with the orientation.
Step 15: Layer 3
This is layer 3, as the name says. Like layer 1, it's missing a blue rod.
Step 16: Adding Layer 3
Sorry about the photo, the side bit should clear things up.
Step 17: The Motor
This part is for the motor (of coarse).
Step 18: Adding the Motor
This motor attaches to the side part.
Step 19: Motor's Rod
The picture is of the rod that clips into the motor with gaps where the motor, white connector and the orange connector go.
Step 20: Adding That Rod With Spacers
Here is a demonstration where the rod goes.
Step 21: The Crankshaft
This is a doulbe crankshaft which is why there's no room for two extra red rods. (an excuse to save pieces).
Step 22: Adding the Crankshaft
There is space for two more blue spacers on the tan rod, enough for the crankshaft.
Step 23: The Lower Arm
Here's the lower arm, there is a large hub as a counterweight.
Step 24: Adding the Lower Arm
This is why a blue rod was missing in layer 1.
Step 25: The Upper Arm
You might've realised this arm is shorter. Good, you should have.
Step 26: Attaching the Upper Arm
This is why there was a blue rod missing from layer 3.
Step 27: The Other Side Bit
This section supports the side opposite the motor.
Step 28: Adding the Side Bit
Put this on the side opposite the motor. The orange connector should clip into the crankshaft
Step 29: Layer 4
This layer Holds the exit track. The last picture is for if you want a split path afterwards.
Step 30: The Exit Track
Almost done! Build this, add it, and thats it!
Step 31: Adding the Exit Track
Just stick it in and you're good to go!
Step 32: Done!!
Now you're done (as the title suggests). Try to make sure there's not much tilt in the room because it added to the trick photography in one of my videos, I mean, HAPPY BUILDING!
