Customizable DragonflY Assault Crossbow

Here it is, a new design aimed at portability, but still packs more than a punch.
It uses a trigger previously seen on the Blockhead, which has never misfired(and believe me,that is important when playing with so much power).
This Instructable features 4 bows, one Y-shaped two normally-shaped and one odd block; all a personal choice. The stock is optional, however it makes it a lot easier to aim and makes it a lot more comfortable. The DragonflY is also very piece efficient and provides excellent firepower for 6 rubberbands.

Facts:
1. Lightweight
2. Comfortable
3. Easily fires 150 feet*
4. Modular: Instructable will be updated with different bow types, scopes and stocks.
5. Wide opening: The front bow is very wide, which means it can fire all sorts of ammo.**
6. Easy loading/Low friction: The trigger has been improved, which makes it easier to load, reduces friction.
7. Powerful: Shoots clean through cardboard.

Review:
http://www.instructables.com/community/Customizable-Dragonfly-Assault-Crossbow-Review/

Like it said, I will update the Instructable with new things for it.
If you happen to have made a good bow,stock or scope, you could always post a picture of it, I will build, make instructions for it in here and of course give you credit or the design.
Ammo will get a special section soon!

Don't forget to rate eh? =d

*Depends on length of handle and number of rubberbands.

Amazing! Outstanding! With the right rubber bands (#64's) and the right ammo (red rod with blue ball and blue rod) it managed to puch a hole through a 3 layer cardboard box. Thank you!

Will post a better parts list soon for a more accurate list ;)

could you try and make an angled handle, that one looks quite uncomfortable
Wicky (author)  shieldsam3 years ago
Yeah, it wasn't the best handle ^^
I was more focussed on making a solid trigger mechanism.


Not anywhere near my k'nex currently, but I do know that this trigger is obsolete.

The first/second picture contains a single-shot trigger, which will fit, but will require readjusting of the wheels on the bow. Might be even worse in terms of comfort ;x

If you really want to get creative, try the 3-shot trigger on picture 3-4, but it might be hard making the bow hold 3 strings. See topic for more info on this one.

do we actuly need to make this?
Wicky (author)  ub3rc00k134 years ago
These are the basic pieces required to build the y-bow
wehe-tehe4 years ago
I built this about a week ago. just got a pic and I love it ! :-) P.S I modded it alot so yay
wickybow.jpg
 is the piece count including the stock
Wicky (author)  imthatguy11254 years ago
Piece count is without stock, as it is optional.
Blackbird174 years ago
is there anyway around the hinge jount?
Wicky (author)  Blackbird174 years ago
Uhm I don't think so, you can try using a trigger like this one(don't build the casing):
http://www.instructables.com/id/S1DC0ZCFEXKLWZR/

or,

Just building the part until pic8 will work, just use a separate rod to hook the arrow onto and fire.

I will try and use a different trigger on my next bow, because a lot of people don't seem to have the hinges.

Sorry if I couldn't be of help =/

outa the reaper, block head and this crossbow, which one would you say had the best balance between, power, accuracy, and reliability, tho its mostly power that interests me.
Wicky (author)  TehPotato4 years ago
The blockhead has the same trigger and is the most powerful one.
razzlekunai5 years ago
I'm gonna build this as soon as you answer this: Which bow has the best balance of power and accuracy?
Wicky (author)  razzlekunai5 years ago
I think it would be the Y-bow as they are all accurate, but that one is the strongest.
Hmm... which bow would wear down rubberbands the quickest? I bet it's the Y-bow...
Wicky (author)  razzlekunai5 years ago
Yes it is the Y-bow, as the rubberbands hit the rod pretty hard every time.
I'm asking you too many questions aren't I? :P Here's another one (as I haven't built it as I said I would lol) How reliable is the trigger? Can it handle #64s tied up?
Wicky (author)  razzlekunai5 years ago
Well the trigger will hold it easily, the red connector on the arrow must be ductaped. (the one in the Ammo Types section) But bows are not made to handle those... One could try though =P
i tried on the quick bow and it bent and became unstable
Wicky (author)  imthatguy11255 years ago
The rubberbands could be too strong or you have too many on. I never saw it become unstable..but it could be possible as the bow is not made to be as sturdy as possible.
this was with 2 strings of 3 64s it works fine with 32s and i tried a ammo of a red rod with a tan clip and a grey clip it has great puncture
Wicky (author)  imthatguy11255 years ago
Yeah 64's are a bit too thick for a small bow, I did make a cannon using four strings of six 64's though =d
was it one of i am canadians
Wicky (author)  imthatguy11255 years ago
Nah, this one was rectangular and had to be put against the wall to load it lol
OK :D Speaking of which, I need to get more duct tape....
Hiyadudez5 years ago
Attached to each set of wheels are there 2 rubberbands tied together?
Wicky (author)  Hiyadudez5 years ago
There are two strings of three rubberbands tied together. See the last picture if you want to know how to attach them.
Do you want me to make a review?? I was planning on building it and do not mind.
Wicky (author)  Killer~SafeCracker5 years ago
If you want to, I don't mind at all =d
Should be up later today. Will you put a link on the instructable??
Wicky (author)  Killer~SafeCracker5 years ago
Yeah I'll do that, thanks for the review.
No problem.
builder9685 years ago
Whoa. Mesa gotta BUILD!!!!
Actually, I'm gonna build my own. The trigger system will be almost exactly the same, though, probably.
Dirtyboyy5 years ago
tank you ;) i realy like it ! 5* < 1000 times :D
rururupert5 years ago
hmm... i dont know which of your crossbows to build-reaper, blockhead, or this one? Which is the most reliable, still keeping good power? 5* on all 3 already
also, which is easiest to build?
Wicky (author)  rururupert5 years ago
Well this has every new improvement I have found till now, the others don't have these improvements.
The Blockhead should be the most powerful as it has the most rubberbands.
This one just aims at making the power portable, yet at the cost of some of that power.

At the moment I have everything taken apart, I am going to make something massive lol =d
thanks alot i think ill make this one-with y bow. now ive just got to get some of those rubber bands lol
knexguy5 years ago
I haven't built anything in a while so I think I'm gonna do this and the VSS.
Can someone please post a picture with the Block Bow on it!?
Wicky (author)  knex_builder_freak5 years ago
3rd Picture on front page:
100_4939 (Large).JPG
WoW I just finished and now I see your picture! Thanks for the fast reply anyway! PS. This is probably the MOST POWERFUL KNEX GUN IN HISTORY!
Wicky (author)  knex_builder_freak5 years ago
Well technically it can look like a gun, but crossbow-wise I did make more powerful things ;p
LoL okay
This looks great. What bullet has the best distance?? By the way I like the version in the second picture best.
Wicky (author)  Killer~SafeCracker5 years ago
From what I heard it would be one with a white connector on the top.
Okay thanks

Nice crossbow, 5*, but remember what I said about making something that is not a crossbow. (ps, I think your the crossbow king)
id have to agree, your number 1 in crossbows wicky :)
lol
Wicky (author)  DJ Radio5 years ago
I could always post a slingshot-sniper like thing for this ;P
knex mad5 years ago
hi I've made the cross bow and its excellent like all the rest of your work 5* and faved but step 6 is more barrel / fore grip not handle because step 7 is the trigger and handle
Wicky (author)  knex mad5 years ago
Yeah I know, but I've grown into using that for the parts =d
AAH! I built this with the BlockBow head, and shot it in my backyard, and it hit the fence DEAD ON, and the fence is 16m away! I've never actually have a gun shoot that far before! :D:D:D
Wicky (author)  agent harmsy5 years ago
Great to know that that bow actually works ;p

I didn't fire this weapon outside though =/
Oblivitus5 years ago
I like it.* Good job.** What is your favorite color?*** **** *If it actually fires 150 feet. **Still subject to possible epic failure. ***I ran out of comments. ****I like making stars. :)
Wicky (author)  Oblivitus5 years ago
Yeah makes for some easy side notes without destroying lay-out =D
Oblivitus Wicky5 years ago
Convenient. :)
Wicky (author) 5 years ago
First Update:
Ammo Types added.
BlockBow added.
Quick,Effective,Bow added.
VeryShortStock added.

Wicky (author) 5 years ago

Oblivitus Wicky5 years ago
Seems like some pretty cool stuff.
Wicky (author)  Oblivitus5 years ago
Gonna add 2 more bows right now and a part to cover the place the stock attaches if you don't connect one.
AWESOME!!!! I will probably build! Fived and Faved.

Hmmm..... Should I build the "Y" Bow or the Normal Bow?
Wicky (author)  benboy2075 years ago
Is your own choice, the Y-bow may be a bit more powerful with a shorter handle.
1. nice 2. i told you to post both ways forward and back so COOL 3. 5*
