Introduction: 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

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

Step 5: 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

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!

do you have to use the blue spacers?

author

yes

I notice the wood had a pre-made hole in it as well as the cardboard...

author
Electroinnovation made it!(author)2008-12-29

Yes but still, how did that hole get there. I only have enough pieces for this and it took me a month to build.

author
guy-man made it!(author)2009-08-17

well it was worth one month

author
Electroinnovation made it!(author)2009-08-17

Yes it was. It was so hard for me to perfect the reinforcement. That took up almost 3 of the 4 weeks.

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

author
Electroinnovation made it!(author)2009-06-13

Yeah that's almost the exact same story as me. lol

author
xadevox made it!(author)2009-06-12

whats up with your name? not to be mean but why is it all numbers? just random? or did u pick it on purpose?

author
Electroinnovation made it!(author)2009-06-13

Actually I used to play Runescape and I traded accounts. That was the name of the account and I stuck with it ever since.

author
Electroinnovation made it!(author)2009-05-21

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.

author
Electroinnovation made it!(author)2009-05-21

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.

author
Electroinnovation made it!(author)2009-03-23

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.

author
Electroinnovation made it!(author)2009-05-14

And it failed so this will be the one and only version. Sorry

PS. I haven't built yours yet but it sure does look good.

author
Electroinnovation made it!(author)2009-05-14

Well I also have a more powerful one that shoots around 220 feet. Its called the Brickster LDS

author
travw made it!(author)2009-03-15

Do you have to make exactly 13? Can you use less?

author
Electroinnovation made it!(author)2009-03-16

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.

Psychic+Master made it!(author)2009-02-19

how do you load this?

author
Electroinnovation made it!(author)2009-03-02

Pull the rubber band on the white wheel and load the ammo an inch in front of the wheel in the track.

author
Chris09 made it!(author)2009-01-14

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.

author
Electroinnovation made it!(author)2009-01-14

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.

author
Chris09 made it!(author)2009-01-15

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

author
Electroinnovation made it!(author)2009-01-19

You have to put the rubber band on the white wheel then load the ammo on the track.

author
Psychic+Master made it!(author)2009-02-19

how does the trigger fire the gun?

author
Electroinnovation made it!(author)2009-03-02

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.

author
thomaswatton made it!(author)2009-03-01

whats the range for this?

author
Electroinnovation made it!(author)2009-03-02

100 feet with standard ammo and 30 feet with the grappling gun attachment.

author
Wicky made it!(author)2008-12-30

It does seem strong, but the hole in the wood makes the piece of wood very easy to break in half, also the red connector on the end of the ammo stops it from piercing through the whole box. If you have pieces left you could try making a fore-grip for extra support. Also I see you use purple connectors on the sides, I do not know on what part is the most tension, but if you can replace those outer purples with yellows, it makes it sturdier.(purple connectors have a tendacy to split apart when pulled on)
I think 4 stars would be fine.

I guess these crossbows want realism over power, as the track causes a lot of friction and slows it down =/

author
Electroinnovation made it!(author)2009-01-01

That is true but it is more accurate than one of your no track versions.

author
Wicky made it!(author)2009-01-01

I think you haven't tried them then...the arrows fly in a straight line and its very easy to aim as I use the tip of the arrow to aim, but I need to get the rubberbands lined up just right with the trigger in height. But I do think tracks can make it more accurate, but my arrows are stabilized at the trigger as it forms some form of barrel.

author
Electroinnovation made it!(author)2009-01-02

Actually, I have built the reaper, blockhead, and my own version. They are very accurate but if you put the rubber band too far to the left or right of the ammo it flies sideways. With mine even if that happens it wont affect the direction of the ammo.

alfpwns made it!(author)2009-01-18

tracks add friction

author
Electroinnovation made it!(author)2009-02-03

Yes but they add accuracy and allow to to do other things like maybe build a grappling gun with the ammo attached to a string. If my camera hadn't died I could post a video.

author
alfpwns made it!(author)2009-01-18

o btw oi got my crossbow 2 shoot 20 ft but i scraped it

author
Electroinnovation made it!(author)2009-02-03

Well then you have to add more rubberbands.

author
Owenmon made it!(author)2009-01-18

Wait... Plastic is more strong then wood? because i shot my most powerful gun yet (soon to be posted) at my WOODEN house and the ball connector broke! =O (there was a dent, though)

author
Electroinnovation made it!(author)2009-01-19

1st of all, almost any crossbow is at least 2x more powerful than the most powerful knex gun on this site(excluding gorkem's and KillerK's) and it is balsa wood. That is a lightweight wood that is easier to shoot through than solid oak wood.

author
Owenmon made it!(author)2009-01-19

Okay. But Gorkem's sniper just has like a million rubber bands on it, it even has a tan lock breech! that's like one of the worst magazine breechers. >:O

author
Electroinnovation made it!(author)2009-01-26

So what that is his. Besides, you have to build a frame strong enough to suppory all of the rubberbands you put on it, so his is pretty stirdy. Aslo, mine only uses 8 rubberbands. The Reaper uses 16 along with many of the high power long distance crossbows you see that are getting all of the glory.
