Introduction: BLOCKHEAD: Precision Crossbow

About: I seem to like building crossbow shaped objects.
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.


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


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

Step 1: Building the Handle

Image 1: Build these two sides of the handle.

Image 2: Build the center of the handle.

Image 3: Different perspective; center of handle.

Image 4: Connect the side with the center.

Image 5: Different perspective; center + side.

Image 6: Add the other side to it as well.

Yup that's the handle, wasn't too hard eh?

Step 2: Building the Trigger

Image 1: Build this part

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

Image 11: Build this

Image 12: Add it to the part of image 10

Image 13: Build these

Image 14: Add the new parts

Image 15: Add the two sides from image 13 together

Image 16: Add spacers and 3 gray connectors

Image 17: Add it to the rest of the trigger

Image 18: Build this part

Image 19: Same part different view image 18

Image 20: Add it as shown

Image 21: Connect shown pieces together

Image 22: Build decal wings

Image 23: Add like so

Image 24: Same as image 23

Phew that's a long step, but now you're done with the trigger =D

Step 3: Building the Bow (block)

Uh not really a bow? xd

Hard bit (Not enough time to take apart >.<)
Image 1: Try to build this by first building the 2 squares of blue connectors, then adding rods

Image 2: Same

Image 3: Same

Hardest part done.

Image 4: Build this

Image 5: Attach them

Image 6: Build this

Image 7: Add like shown

Image 8: Build these 4 layers

Image 9: Build 2 of these

Do the following on both sides!!
Image 10: Add a layer

Image 11: Add the top layer
Should be done with both sides now

Image 12: Should look like this

Image 13: Attach as shown, to get a block, not bow

Image 14: Build these 2 parts

Image 15: Add them like shown

Step 4: Adding Rubberbands

Just add the rubber bands

Image 1: Make 4 of these strings, these are 4 rubber bands long, the length may vary with the length of the handle

Image 2: Put them like so

Image 3: Then just connect them with the block (bow)

Image 4: 1st rubber band on the trigger

Image 5: Same as image 4

Image 6: 2nd rubber band, read note

Step 5: Assembling the Crossblock (lol?)

Image 1: This is pretty hard, time was nearly running out, CHANGE your handle to match the one in this picture!

Image 2: The bow is very easy; it just snaps on

Image 3: And before I forget, make this and put it somewhere on the handle

Image 4: Same

Image 5: Same

Image 6: Attach anywhere you want like so

Step 6: Ammo

Loading and shooting is covered in the video's on the first page.

This can shoot the same ammo as the Reaper, hell I even used the same picture =x

Kinda sucks that I don't have the crossbow here while making the Instructable...
If you look at the handle close to the trigger, you'll notice you can pack it with arrows =p

Step 7: Finished!

Yay its done! Now you can go out shooting stuff =D
It can be made more powerful making the handle longer, but if made too long, it doesn't fire long arrows like piercing ones..
And if you have an extremely long handle, ductape might help with red connectors that snap off under the strain.

.. Uh yeah don't ever shoot people with this thing, as it can be very dangerous/lethal =d
And I hope the instructions are clear enough, as I couldn't make additional pictures >.<

Image 1: Yup quite some improvement over this =D
