Introduction: Customizable DragonflY Assault Crossbow

About: I seem to like building crossbow shaped objects.

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 8(Pic10): Add together.

Step 2(Pic3,4,5): Add these together as shown.
Step 3(Pic6): Build these parts.
Step 4(Pic7,8): Add the parts as shown.

Step 7: Trigger

The most complicated part, also the part I would be proud of.

Step 8: Pointy Stock

Pretty comfortable, if not a dangerous melee weapon. optional

Ofcourse the coolest thing to do =d

Step 2(Pic3): Attach like so.
Step 3(Pic4): Attach bow like shown.
Step 4(Pic5): Attach stock like shown.

Step 12: Adding the Rubberbands

It is pretty hard to get the rubberband in, just take some side panels off. You'll never have to do this again, as I haven't seen a rubberband snap here.

Step 13: Ammo Types

These are all the types of ammo it will fire, there may be some I haven't tried yet.

Step 14: 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 ;)

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

    2 replies

    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.

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

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

    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

    Piece count is without stock, as it is optional.

    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 =/

    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.

    1 reply

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

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