Introduction: K'nex Compound Bow

https://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.

The only problem with something like this is that it would really mess up your grey rods.

it was quite easy to make it hasnt snaped on me but the rubber bands because they were old and it works fine so I am going to get new rubberbands to put on the bow and I made my own arrow holder for my arrows

He said it gets 70 feet. I imagine it will shoot at least 50 feet.

Wow that is pretty good for a bow.

I haven't built it, so that is just a guess.

do you have any ways to strip it of some pieces so i get nearly the same performance without using so many pieces?

author
Matrix-technician made it!(author)2012-08-03

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

author
_Murdock_ made it!(author)2012-07-24

something to try would be high-strength fishing line. I've used Berkley Fireline and it works beautifully

author
Jedi_man made it!(author)2012-05-31

Ok, I made this from the pics, but HOW DO I STRING IT! :(

author

Never mind, I looked at the comments more and you told a guy that it was string.

This is pretty cool and all. No offense, but plasmaspy released one years ago that was similar to this and sturdier >.>

author
Matrix-technician made it!(author)2011-10-16

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[)

author
apples%21%21%21%21%21 made it!(author)2011-10-17

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.

author
Matrix-technician made it!(author)2011-10-17

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.

author
apples%21%21%21%21%21 made it!(author)2011-10-17

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.

Yea, it sure does! :p You can't kill anything with it ofcourse.
