Introduction: Customizable DragonflY Assault Crossbow

Picture of 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.

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

Step 14: Done!

Picture of Done!

Yay! You're done with building, now go on and have some fun =D

You can come back to this Instructable and build a different bow, stock, scope..
Try experimenting with different kinds of ammo.

If you happen to have made a good bow, you could always post a picture of it, I will build, make instructions for it and of course give you credit or the design.
I will make a new section for ammo when I have the time.

Also keep in mind that I have thoroughly tested the damage it will do to humans..and let me tell you, it hurts ;p
Also avoid shooting straight into walls, unless you have some spare pieces and a vacuum cleaner nearby.

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 ;)

shieldsam (author)2011-06-24

could you try and make an angled handle, that one looks quite uncomfortable

Wicky (author)shieldsam2011-06-24

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.

shieldsam (author)Wicky2011-09-30

thanks!

shieldsam (author)2011-07-14

what do you mean by flings arrows very late?

Wicky (author)shieldsam2011-07-14

Good one, I have no clue what I said two years ago =s

Its just a normal bow, nothing special on this one, so dunno =d

danbaha (author)2010-08-31

Awesome

cokeman (author)2009-11-28

the ammo flung back and hit me in the face why ?

tjdtjd1 (author)cokeman2010-04-14

this may sound cruel but....
roflcopter

cerj (author)cokeman2010-02-09

 I'm sorry but i laughed so hard to that. i can just imagining the rod go up your nose XD

ub3rc00k13 (author)2010-03-19

do we actuly need to make this?

Wicky (author)ub3rc00k132010-03-19

These are the basic pieces required to build the y-bow

wehe-tehe (author)2010-03-08

I built this about a week ago. just got a pic and I love it ! :-) P.S I modded it alot so yay

imthatguy1125 (author)2009-10-19

 is the piece count including the stock

Wicky (author)imthatguy11252009-10-19

Piece count is without stock, as it is optional.

Blackbird17 (author)2009-08-28

is there anyway around the hinge jount?

Wicky (author)Blackbird172009-08-29

Uhm I don't think so, you can try using a trigger like this one(don't build the casing):
https://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 =/

TehPotato (author)2009-08-19

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)TehPotato2009-08-19

The blockhead has the same trigger and is the most powerful one.

razzlekunai (author)2009-04-09

I'm gonna build this as soon as you answer this: Which bow has the best balance of power and accuracy?

Wicky (author)razzlekunai2009-04-09

I think it would be the Y-bow as they are all accurate, but that one is the strongest.

razzlekunai (author)Wicky2009-04-11

Hmm... which bow would wear down rubberbands the quickest? I bet it's the Y-bow...

Wicky (author)razzlekunai2009-04-12

Yes it is the Y-bow, as the rubberbands hit the rod pretty hard every time.

razzlekunai (author)Wicky2009-04-17

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)razzlekunai2009-04-18

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

imthatguy1125 (author)Wicky2009-06-23

i tried on the quick bow and it bent and became unstable

Wicky (author)imthatguy11252009-06-23

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.

imthatguy1125 (author)Wicky2009-06-23

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)imthatguy11252009-06-23

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

imthatguy1125 (author)Wicky2009-06-24

was it one of i am canadians

Wicky (author)imthatguy11252009-06-24

Nah, this one was rectangular and had to be put against the wall to load it lol

razzlekunai (author)Wicky2009-04-18

OK :D Speaking of which, I need to get more duct tape....

Hiyadudez (author)2009-06-20

Attached to each set of wheels are there 2 rubberbands tied together?

Wicky (author)Hiyadudez2009-06-20

There are two strings of three rubberbands tied together. See the last picture if you want to know how to attach them.

Killer~SafeCracker (author)2009-06-13

Do you want me to make a review?? I was planning on building it and do not mind.

Wicky (author)Killer~SafeCracker2009-06-14

If you want to, I don't mind at all =d

Killer~SafeCracker (author)Wicky2009-06-14

Should be up later today. Will you put a link on the instructable??

Wicky (author)Killer~SafeCracker2009-06-14

Yeah I'll do that, thanks for the review.

Killer~SafeCracker (author)Wicky2009-06-14

No problem.

builder968 (author)2009-05-19

Whoa. Mesa gotta BUILD!!!!

builder968 (author)builder9682009-05-19

Actually, I'm gonna build my own. The trigger system will be almost exactly the same, though, probably.

Dirtyboyy (author)2009-05-10

tank you ;) i realy like it ! 5* < 1000 times :D

rururupert (author)2009-04-17

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

rururupert (author)rururupert2009-04-17

also, which is easiest to build?

Wicky (author)rururupert2009-04-17

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

rururupert (author)Wicky2009-04-18

thanks alot i think ill make this one-with y bow. now ive just got to get some of those rubber bands lol

knexguy (author)2009-04-17

I haven't built anything in a while so I think I'm gonna do this and the VSS.

Vynash (author)2009-04-14

Can someone please post a picture with the Block Bow on it!?
