Picture of Knex High Power Crossbow
Check out my new gun. Check This out.This is one of the most powerful single track crossbow on this site. It can go through 4 layers of cardboard and shoots over 100 feet straight. My patented ammo rarely twists or turns while it can still pierce very well. Please comment and rate. Look for version 2 in a few months. It will be even better than ever. The second video went through balsa wood and the cardboard.

Step 1: Barrel

A super strong and sturdy design.

Step 2: Handle

I couldn't take this apart but it shouldn't be too hard to build. Look carefully.

Step 3: Bow

The longest step.

Step 4: Support

Picture of Support
This gives you an area to hold and strengthens the handle.

Step 5: Rubberbands

Picture of Rubberbands
Use 2 strands or if you are strong and daring, 3.

Step 6: Final Assembly

Finally you are done with my best instructable.

Step 7: Destruction

Picture of Destruction
Go crazy. Here is a picture of the ammo. There also is a missile and night shot. Do not aim a people as it will hurt.

Step 8: Grappling Gun

Shoots 30 feet and it is recommended to build multiples and then replace the whole thing instead of winding it up.

now, mine isn't as good as your version, but my crossbow that i made uses less pieces and fires pretty darn well. I might post some instructions on how to make my crossbow.

but nice one man!

Cool. Send me a message if you get around to making the instructable

i built it i made a mod to it and used 10 strings of rubberbands!!!!!!!!!!!!!!!!!! ;) :) i used a arrow in it and it made a hole in the trash can lol

do you have to use the blue spacers?
Electroinnovation (author)  chip01525 years ago
I notice the wood had a pre-made hole in it as well as the cardboard...
Yes but still, how did that hole get there. I only have enough pieces for this and it took me a month to build.
well it was worth one month
Electroinnovation (author)  guy-man5 years ago
Yes it was. It was so hard for me to perfect the reinforcement. That took up almost 3 of the 4 weeks.
Its not bad.

ooooh.. i used to play runescape but my java is messed up bad right now, so i can only play it at my friend's house every once in a while
Electroinnovation (author)  xadevox5 years ago
Yeah that's almost the exact same story as me. lol
xadevox5 years ago
whats up with your name? not to be mean but why is it all numbers? just random? or did u pick it on purpose?
Electroinnovation (author)  xadevox5 years ago
Actually I used to play Runescape and I traded accounts. That was the name of the account and I stuck with it ever since.

Guess what. I just created a realistic crossbow trigger. All you have to do to load it (after a short sequence to prepare it) is pull back the rubberband and let it go. It has a latching lever with a quick release. I am currently working on it. It is going to be V2 of this.
And it failed so this will be the one and only version. Sorry

Because that would be a bit difficult for a crossbow that uses a track. Those are a bit bulky and are not good for these types of smaller crossbows.

Well that is true BUT the heavy cannons use 2 tracks and the Dragonfly actually doesn't have a track. Sorry but I'm not building any more crossbows of this version. I may build other ones though so keep your eyes open.

Do you have to make exactly 13? Can you use less?
Electroinnovation (author)  travw6 years ago
You can use 4 less and make 9 or you can make 4 more for a total of 17. You just have to change the support slightly so it fits the size.
how do you load this?
Pull the rubber band on the white wheel and load the ammo an inch in front of the wheel in the track.
Chris096 years ago
How do you attach the rubber bands and where to? I think i've got it. But how do you load and fire it? I can pull it back, but there isnt anything that locks the ammo in place... But otherwise, good stuff.
Electroinnovation (author)  Chris096 years ago
The friction from the barrel holds it in place and sorry about the rubberbands. 8 go on the bow and use one more on the trigger. It is easy enough to do without pictures.
i've worked out the rubber bands on the bow. i think i've sussed the tigger. its just, how does the ammo stay in place? I load it, pull it back and then it just flies. =S
Electroinnovation (author)  Chris096 years ago
You have to put the rubber band on the white wheel then load the ammo on the track.
how does the trigger fire the gun?
The trigger stops the white wheel from spinning and when you pull the trigger, the rod pulls away and allows the wheel to spin which lets the rubber band go.
whats the range for this?
