Instructables
Here it is, the block-bowed-crossbow called BLOCKHEAD.
(V6 in the series)

It features a massive punch, while still able to use a true-trigger perfectly.
One can still detach the trigger to be able to fire 4 arrows in a row like the Reaper.

Although I was in a hurry (work after school \o/ ), the pictures should be fine.
Just in case I have a .rar archive included with all the full-sized pictures (2576x1932) in it, if you need to take a better look.

PRO's:

Extremely powerful
Long range
Very accurate
Perfectly working true-trigger
Very sturdy where it needs to be
Easy to mod

CON's:

Not the fastest loading with trigger (goes faster once you get the hang of it)
The front handle needs improving
Its very heavy (dunno if this is bad =p)

Two video's, showing trigger and damage





Here is the .rar file

Image 2: Build the other side

Image 3: Other viewpoint of Image 2

Image 4: Other viewpoint of Image 2

Image 5: Attach both sides to each other

Image 6: Build these parts

Image 7: Add them to the construction

Image 8: Build these two parts

Image 9: Build this thingy

Image 10: Add the thingy and connect the two sides

 About how many yellow cons does it use?
In all honesty, about as much as my gun does... this thing dispenses with the need for solid rows by suspending the ammo with the RB's instead of using a track... also less solid-I built my gun to be usable as a hammer with no loss to functionality.
Wicky (author)  mettaurlover4 years ago
Kinda like this one, as in hammer? =d

Not so much-mine's shorter and doesn't have a bow, and has advantages in those regards-just as powerful, while being more predictable and lighter.

I think that the gun looks quite cool, but my only problem is the small ammo. Doesn't look like i can get very much damage out of it.
Wicky (author)  nball1995 years ago
You'd be suprised, all that power concentrated on a little arrow...

Well I am sure it would require a lot of ductape, but it wouldn't be that hard at all; after all the first cannon was based off the Reaper. The most damage I have ever seen with any k'nex weapon in one shot would be this(impact from the Decimator on plastic radio):

 can you link the wep in the last pic?

Wicky (author)  smattman225 years ago
I never posted that weapon, I only made a forum topic about it:
http://www.instructables.com/community/Decimator_Crossbow_v7/

We are moving right now, so I don't have any k'nex at hand =/
 aww :*(  im sorry about the no knex thing :(

Wicky (author)  DELETED_Gilrostwo5 years ago
I think metal knex pieces would be great, although it would be impossible to use the connectors xd Carbon fiber would at least take the problem of vaporizing connectors out when hitting walls.
Why would it be impossible to use metal connectors??
Wicky (author)  Killer~SafeCracker5 years ago
Because if you insert a rod in a connector it slightly bends to fit the rod in, using metal this would be quite hard =d
what about a meatal rod flatend at one end and the other for the tip drill a hole in it
True, I forgot about that.

Wicky (author)  DELETED_Gilrostwo5 years ago
I wonder if carbon fiber is too light though, as the current problem is that the arrow is too light. But if I would ever see those on eBay I would surely buy them =d

this thing went throught 2 pices of cardbord then made a hole in my wall. my parents got so mad.
Wicky (author)  yofatmama455 years ago
Oops? My room is covered in dents =d

How the the trigger work?
How *does* the trigger work?
Wicky (author)  Master_Zane5 years ago
When you pull back the red connectors on the trigger, the blue clips attached to it lifts up the orange connector, which pulls down the hinge on the back and pulls down the blue rod; releasing the arrow. Took me quite a while to build lol.

I am sure I did, it was used on the Reaper; IaC's cannon was built after that.
(removed by author or community request)
It has the same principal though.

I am in the progress of making this. I was thinking about all the fun I could have shooting my neighbors, but a question suddenly formed into my head: What type of rubberbands does this use?
Wicky (author)  razzlekunai5 years ago
I never selected these on purpose, but these are just standard cheap small thin rubberbands:
Picture 052.jpg
WOuld #64s work as well, or can the trigger withstand only so much pressure?
Wicky (author)  razzlekunai5 years ago
I have a bad experience with bigger rubberbands, because they tend to flip the arrow around, but if you ductaped the trigger, it should be able to hold it I guess..only one way to find out though...try it =/

Wicky (author)  DELETED_Gilrostwo5 years ago
Ow =/
Glad you're not hurt though, although it could've been worse; a friend of mine got hit on the knuckle by a red connector...propelled with 20 #64's .. ductaping arrows is essential when playing with massive power O.o'
