The Chu-ko-nu was created around 181-234 A.D. by chinese strategist Zhuge Liang. I have recreated his invention out of k'nex. I know that there are other repeating crossbows on this site, but i believe that this is the first instructable for a Chu-ko-nu style repeating crossbow. Here are some basic stats about my weapon:
Range: 30-40 feet. This is moderate range and I know most crossbows can shoot farther than this, but it is pretty good for the type of crossbow i think.
Magazine holds 9 red rods. But it only shoots 8 of them. The last one usually falls out because there is no pressure holding it in, but sometimes you may get lucky.
Power: It is not very powerful, but with a sharpened rod, you can get it to stick in cardboard
Piece count: (To make sure you have all of the pieces) Also if you do not have enough and would like to know other ways, please post on this instructable or pm me, i will be glad to help.
Rods: stock+bow+lever+magazine=total
green: 35 + 2 + 10 + 68 = 115
white: 44 + 58 + 6 + 67 = 175
blue: 44 + 23 + 4 + 16 = 87
yellow: 8 + 68 + 0 + 3 = 79
red: 11 + 0 + 8 + 0 = 19
gray: 0 + 0 + 4 + 0 = 4
Connectors: stock+bow+lever+magazine=total
gray: 36 + 18 + 10 + 26 = 90
light gray: 0 + 0 + 2 + 6 = 8
orange: 9 + 0 + 0 + 37 = 46
red: 8 + 6 + 0 + 5 = 19
green: 8 + 18 + 4 + 30 = 60
yellow: 22 + 54 + 6 + 36 = 118
white: 8 + 20 + 2 + 5 = 35
purple: 40 + 0 + 2 + 8 = 50
blue: 1 + 0 + 2 + 0 = 3
Misc: stock+bow+lever+magazine=total
blue spacers: 4 + 0 + 0 + 16 = 20
small wheels: 0 + 2 + 0 + 2 = 4
rubber bands: (this depends on the size) I used 4
duct tape
Uses a total of 932 pieces. As you can see, the magazine uses lots of small rods, so it will be complicated. Lets start with that to get it out of the way.

Signing UpStep 1: Magazine(part 1)
I am going to split the magazine into several steps to make it more manageable.
Note that I have the steps on the picture as well. If you find that easier.
Steps:
1. Make 2 of these
2. Add white connectors and blue spacers to one side
3. Connect the other side
4. Make this
5. And this
6. And this
7. Connect the finished product from step three to step 6
8. Put step 4 and 5 on top of the other thing you built, and use white rods to keep the top layer attached. Also add green rods inside the green connectors, they won't stay right now, but they need to be there.
9. Get a strip of duct tape about that long and wide.
10. Wrap the duct tape around the bottom and up onto the green connectors like this
Done with the lower track of the magazine!
