Introduction: Knex 'wheeled Crankshaft' Ball Lift
Step 1: Parts You'll Make
Each piece is a step (there is one hidden at the top).
Step 2: Main Scaffold
This will be the main scaffold. Notice how there are no red rods connecting the middle, and how some rods (tagged) are different sets of pieces.
Step 3: Additional Scaffold
A quick addition to the previous step. I just didn't want too much in one step.
Step 4: Aligner
This makes sure the ball holder doesn't move away from the entrance track.
The larger rod must be a 'gold rod'. (They're the same size as a red rod, but come with specific spacing.)
Step 5: Wheel Supports
These support the wheel when they go up and down. Notice the gap in them.
Step 6: Adding the Wheel Supports
Remember how you had to have a different version of the red rod? This explains it!
Step 7: Ball Aligner Aligners
These parts help align the wheel aligners, and the more complicated part is the exit track.
Step 8: Adding Those Pieces
Add them where you see them in the picture. Check the orientation.
Step 9: Ball Holder
This is the ball holder. The wheels align them, the rod (above it) attaches to the crankshaft, and the connectors (below it) aligns it.
Step 10: Add the Ball Holder
Easy storage, and better done now than later. Make sure the rods align with the wheel.
Step 11: Crankshaft Pieces
This is double layer, but you only need a single rod for the second layer. You don't need these exact wheels for a counterweight, but you do need a counterweight.
Step 12: Adding the Crankshaft
Just 8 connections.
Step 13: Motor Part
A small addition to the scaffold which holds the motor.
Step 14: Adding the Motor Piece
Just 8 connections (depends what counts as a connection).
Step 15: Extra Counterweight
Because you can never have enough counterweights.
Step 16: Entrance Track Mechanism
There must be gold connectors.
Just 2 connections.
Step 18: Entrance Track Floor
Make this 'white floor' with a gap in it to align with the entrance track. Don't forget the 4 pieces above.
Step 19: Adding the Entrance Floor
Use the extra pieces in the previous step to attach the white floor. Also use the Y-clips.
Step 20: Finished!
You're finished! If you plan on increasing your floor, causing momentum, add the pieces in the second 2 pictures to slow them.
