My Knex Crossbow History Answered
I first had this up as slideshow, but the forums seem to be a better place for it.
1st picture (Crossbow V1) This is a picture from the first crossbow i made and if you look at the other crossbow you can see that this one is a predecessor of it.
This one however is a bit harder to fire with, since you need to lower your crossbow right after firing, or get smacked in the face by an arrow bouncing back :P
It can get about 80 to 100 feet(if fired well ofcourse) and it could be seen as a light version of
the other crossbow. It can make a hole in a piece of cardboard (from a box)
If instructions are needed, I will post an Instructable.
2nd picture(Crossbow V2) already has instructions posted. Actually won a prize with it too :D
It fires 120-150 feet, also depending on wind like most arrows would do. Goes through straight through cardboard.
3rd picture (Crossbow V3 aka Ballista ) No instructions posted, because there was not enough difference between V2 and V3 and is a bit on the heavy side :P
It has enormous power, but due to having a trigger it didn't fire further then V2.
Explodes small plastic boxes, CD's, obliterates red connector of the arrow if fired straight into a wall.
4th picture (Crossbow V4) never got finished because it was way too heavy and therefore it was nearly impossible to find a good handle for it. Had a good time dismanteling it....
Not much to mention about this one, since it never fired.
5th picture (Crossbow V5 "Reaper") is nearly complete and is fully functioning.
It uses 4 rubberband strings to do the damage. It also has a new trigger system so that it can hold the full power of the 4 rubberband strings.

6th picture A smaller, more piece efficient crossbow, although not as powerful as the Reaper, it is compact and easier to use.
