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. <br> <br>but nice one man!
Cool. Send me a message if you get around to making the instructable
dude last night i almost finished it after an hour and a half, and then accidentally pressed cancel...sucked.
i built it i made a mod to it and used 10 strings of rubberbands!!!!!!!!!!!!!!!!!! ;)&nbsp;:) i used a arrow in it and it made a hole in the trash can lol<br />
do you have to use the blue spacers?<br />
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
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.
great...this gun made a hole in my wall
great gun tho! i built it. its pretty fun to shoot. Im trying to find a way to use killerk's fins on this gun.
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
Yeah that's almost the exact same story as me. lol
whats up with your name? not to be mean but why is it all numbers? just random? or did u pick it on purpose?
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
good work , try to make my gun he is a lot more powerfull maby you try it out ;) 4* <br/>
PS. I haven't built yours yet but it sure does look good.
Well I also have a more powerful one that shoots around 220 feet. Its called the Brickster LDS
Do you have to make exactly 13? Can you use less?
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.
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.
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<br/>
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?
100 feet with standard ammo and 30 feet with the grappling gun attachment.
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)<br/>I think 4 stars would be fine.<br/><br/>I guess these crossbows want realism over power, as the track causes a lot of friction and slows it down =/<br/>
That is true but it is more accurate than one of your no track versions.
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.
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.
tracks add friction
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.
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)<br/>
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.
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
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.
Its good, but i think that gun would be kinda heavy so i woulden't want a regular tigger
Well what kind of trigger would you like??????????????
What i mean is i think the trigger should be on a differnt spot, like on top of the barrel
it don't looks very powerful...
