http://www.instructables.com/id/Compound-Bow/Here's a compound bow i made using various other bow designs from around the web. I used the k'nex loopin' lightning rollercoaster kit for the peices. It is quite large compared to most other bows on this site measuring a whopping 2 feet. It has an effective range of 40-50 feet.This means it can cause damage up to that distance, but the arrow will fly up to 70 feet or more if you don't hit anything. And yes, before anybody says anything about it not having cams, look at pic#9, you can see that i used 2 grey rollers on the end of each limb as the cams, so this is a true compound bow, not a recurve or elastic powered. Another benifit of the arrow rest design i used allows the rod(arrow) to fly straight. It doesn't flop or spin sideways in the air. This bow uses so many pieces(237) :o that I could not explain in words how to make. I used Darth Tso's design as the basis for the main body. After that i added almost everything you see to the bow including the limbs, handle, sight, and arrow rest. The link to the original is at the top of page. This is the first k'nex anything i've ever made, so don't go on about how crap it is. :L I would aprreciate positive comments, and constructive critisism.

nice bow dude
_Murdock_ says: Jul 24, 2012. 12:53 PM
do you have any ways to strip it of some pieces so i get nearly the same performance without using so many pieces?
Matrix-technician (author) says: Aug 3, 2012. 8:40 PM
Sorry to take so long to get back to you. Um, actually I do. Just check out the link, it will take you to an extremely simplified version of this. It's not as sturdy but it shoots just as far.

AWESOME! 5 *s! Oh and, can you use string instead of rubber bands? I don't want the bands to snap on me if I make it... O.O
_Murdock_ says: Jul 24, 2012. 12:56 PM
something to try would be high-strength fishing line. I've used Berkley Fireline and it works beautifully
jedijaxson says: May 31, 2012. 3:04 PM
Ok, I made this from the pics, but HOW DO I STRING IT! :(
jedijaxson says: May 31, 2012. 1:43 PM
Never mind, I looked at the comments more and you told a guy that it was string.

Frikin' awesome :) . Now, where is my kid's knex? Will build this at home. Keep up the good work!
apples!!!!! says: Oct 14, 2011. 3:01 PM
This is pretty cool and all. No offense, but plasmaspy released one years ago that was similar to this and sturdier >.>
Matrix-technician (author) says: Oct 16, 2011. 7:40 PM
Thanks! I'll have to check that one out. As far as sturdiness is concerned, my 6 year old nephew plays with it frequently. I have not had to put it back together once since he took it on his first epic quest of adventure. X[)
apples!!!!! says: Oct 17, 2011. 7:18 AM
Haha, well maybe not particularly in the overall sturdiness as the limb sturdiness/tension capabilities. I had to tweak his a little bit, but it wound up holding like 20ish pounds and that's all I tried.
Matrix-technician (author) says: Oct 17, 2011. 3:29 PM
Yea, this is a VERY beefed up version of Darth Tso's bow. If you want to use it for serious K'nex warfare it would have to be bulit in a similar manner as what I did.
apples!!!!! says: Oct 17, 2011. 7:40 PM
Well Darth Tso's was a stick lol, so I'd hope so. Plasmaspy's came out around the same time that Tso's did but it was far more advanced and has limbs that are not as technical as yours but had more strength.
kare1981 says: Oct 15, 2011. 5:12 AM
Cool! Does it really can work?
Matrix-technician (author) says: Oct 16, 2011. 7:38 PM
Yea, it sure does! :p You can't kill anything with it ofcourse.
evilpooh says: Jan 30, 2011. 10:25 AM
Ok maybe I'm stupid, but how do you sting and fire it. For the life of me I can't get it to work
JazzBoy says: Aug 30, 2011. 10:27 PM
lol
Matrix-technician (author) says: Jan 30, 2011. 12:51 PM
ok, here's what you do to string the bow. Click the link at the top of the slideshow. :)
evilpooh says: Jan 30, 2011. 4:01 PM
Thanks, I got it strung right now but it only fires about a foot and if I pull back any farther the limbs come of
Matrix-technician (author) says: Apr 28, 2011. 7:22 PM
Sorry it's taken me so long to reply. If a string will not work for you, you can easily use an elastic band.
slimshaddy says: Feb 8, 2011. 3:04 PM
i made it and it works pretty good.
99igo says: Feb 11, 2011. 1:18 PM
What rubber bands did u use and what's the ammo
Matrix-technician (author) says: Feb 11, 2011. 6:56 PM
I did not use rubber bands. I used some common thread i had lying around. I believe i bought it at wal-mart a while back for a school project, it's pretty thick as you can see. The ammo is common gray rods, look at pic#6. I have a green adapter pice as the "broadhead", the pointy part.
