This is a K'nex pinball machine I built. I really hope you like it and vote for it. Also don't hesitate to the build your own and improve it. Please comment as well.
Step 1: Frontal Support
Step 2: End Support and Scoreboard
Step 3: Field Support
Under the playing field is a sort of exoskeleton. It consists of a large platform with railings and supporting ribs running through the middle and sides. Theses are essential to hold the weight of the field.
Step 4: Build Your Field!
This is the part to get creative. You basically build a court out of pieces laid side by side and connected together. And then you put walls and holes where needed to implement your tracks. (See video)
Step 5: Pins and Plunger
Step 6: Tracks
Step 7: Scoring
I score this game by time. I build a timer on to the scoreboard. Every minute = 100 points. For example If you were able to keep the ball alive for 1min. 35sec. you have 135 points. Make records and dominate all others!
