Introduction: Knex Double- Decker- What- The- Hecker Pinball Machine Instructions
(The 4th picture shows where they are.)

If you really want a challenge involving long building processes and high piece amounts, then enjoy this instructable. If you have any questions regarding step clarity, let me know and I answer you(almost immediately). For now, this will be my only instructable. Enjoy! Please rate!
I've also took the pictures with a canon HD video camera so the pictures came out crystal clear, clear enough to be manageable as a pdf instructable. The pictures are over 2000x3000 in size and are over 950 Mb's worth of uploading.
Below is a video showing how to play it and also some of the bugs this design still has in it.
Step 1: The Big Piece Count
This may take you a while. Also, micro knex black gears and chain links will be used.
blue 3d- 451
purple 3d- 533
light grey- 11
gold tubing connectors- 76
medium tire rim- 5
medium tire tread- 1
small tire- 1
red gear- 3
blue gear- 3
grey electric motor- 1
purple flexi rod- 2
9- hole panel- 3
little triangle panel- 3
3- hole triangle panel- 7
orange flexi rod- 14
small square panel- 1
gold tubing splice- 10
blue spacer- 141
silver spacer- 234
tan lock- 40
blue clip- 20
y- clip- 29
black rod- 8
tan rod- 2
rubber bands- 12
micro knex black gear- 3
micro knex chain link- 45
knex balls- 3
GRAND TOTAL- 5700
Step 2: Lower Framework, Plunger Path, and Ball Collect Ramp
This step is the first longest step in the project. The dollar bills refer to the position of the area of the part. Look carefully at each picture.
Step 3: Lower Play Area, Lift Passage, and Drop Gate Pully System Tires
The second longest step. Take your time and carefully attach step 2 to 1 which is difficult.
Step 4: Legs
Now let's build the legs.
Step 5: Drop Gate Pully System
I would recommend thinner string for smoother movement. You will be working under the model so be careful.
Step 6: Upper and Lower Flipper Systems
This step is a little tricky. Look at the pictures very carefully.
Step 7: The Plunger
A short step.
Step 8: Ball Release System
My favorite part in the whole model. Follow the pictures carefully.
Step 9: Upper Play Area
Another piece consuming step but the last of them.
Step 10: Lift System
Now things get mechanical!
Step 11: Play Area Walls
Very important pieces! Attaching these walls may be a little tricky so try not to push too hard when snapping them onto the play area. You don't want to damage the play areas because it is very difficult to get under it to repair it.
Step 12: Motor and Gearbox
A complicated step. Look at the pictures carefully.
Step 13: Scoring Mechanism
The cool bit that keeps score which works like a ratchet. You will also need scissors, a sharpie, strip of paper, and scotch tape.
Step 14: Orange Ramp
The almost impossible to hit ramp.
Step 15: Rubber Band Bumpers
Yay, the last step!
Step 16: A Few More Tips Before You Play
You are done! Just a few more tips on how to play. Scoring is done when the ball reaches the score chute and a point will be awarded. The ball will shoot back down to the bottom play area and the process is repeated seven more times until you reach 8. The red connectors mentioned earlier in the motor section controls the reset sequence of the drop gate. This is normal mode. Remove them for easy mode which will disable the drop gate from blocking the lift passage. If the drop gate doesn't fully lock when reset, adjust the string attaching it to the motor section. Same situation goes for the ball release system. Have fun!
