Introduction: Regular Rubberband Knex Bow

I said in my group that I will post this, so here it is.

I was fiddling around with my crossbow and came to this.
This is a normal bow that uses a chain of thick rubberbands, so it needed to be very sturdy and after i made it very sturdy, I believe it will even survive if you let it fall down the stairs.

I found that it was near impossible to let it shoot grey knex rods, so I chose for wooden or plastic arrows.

NOW FINISHED
_______________________________________________________________
The camera works better in daylight :D
And is even better then on the pictures i posted :P
________________________________________________________________

Step 1: Build the Inner Frame

You might be very familiar with this part if you made my crossbow.

Pic 1: Bottom halves of inner frame (dont forget to stick on the green rods :P)
Pic 2: Top halves of inner frame
Pic 3: Combined halves of inner frame

Step 2: Combining Inner Frame

This step can be very hard, you can make this however you want, as long it sturdy.

If you try mine then here are some pictures

Step 3: Making Bow Sturdier

pic 1: Just add the rods as shown in the pictures(Please use Yellow rods instead of the Red rods!)
pic 2:
pic 3: Add this to both sides
pic 4: Add all these damn pieces on the other side aswell, after that connect the green rods first, then see next pic
pic 5: Add the white rods including the grey connectors
pic 6: This is how it should look like by now
pic 7: You want 8 of those things
pic 8: Add them to the grey connectors on the front
pic 9: Put them on the back aswell
pic 10: Make these
pic 11: Make 4 of those
pic 12: Connect it together
pic 13: Take the yellow rods with wheels off and put the very thick rubberbands around them
pic 14: Stick them back in place

Step 4: Loading and Launching

Slide your arrows through the hole in the middle and then against the rubberband and pull it back.

Do not fire at siblings :P
And do not fire at living things either, cause if you use proper arrows you may injure them XD

author
Shadowpom (author)zap892010-08-16

a compound bow is the same size as this and a recurve/longbow would be alot larger

author
Trogador (author)zap892008-08-08

He meant regular as compared to his crossbow.

author
Wicky (author)something942009-08-12

You can use red or green connectors instead.

PS: What a horrible camera I used, I am surprised you can build it =d

I thought of a way to make the arrows. super glue 2 gray rods together and sharpen the front of it. Just an idea.

author
Wicky (author)PieMan13572008-05-24

Never thought of that...I don't think the super glue will hold the arrow in one piece though...as from what I have seen Knex bends alot when fired upon something using great force. I never have any super glue though :P

How do u make knex arrows for this bow? i tried but they allways break

author
Wicky (author)magician8472008-05-21

Like it says on the intro, it does not fire knex, but you could try a long piece of thin round wood. I found one with a sharp point on it :P

author
fret315 (author)2008-04-24

this is so cool I might make it today sometime

author
knexguru (author)2008-04-22

what does it shoot

author
pls (author)2008-04-16

looks like it would also be affective just flailing it around at someone.

author
Wicky (author)pls2008-04-16

It could be, but you can't move it quick since it weights alot lol Hmmz, that would it a ranged AND melee weapon :P Just look at this picture(it must be in this instructable somewhere), this would be even more effective :o(Just push all those red rods up) :D

author
oldsmobilefreak (author)2008-01-18

what should i use instead of wooden or plastic arrows

author
Danny A (author)2007-10-22

I moded it and it is so strong you can drop it from 3 meters and it doesn't break. it used up all of my Knex. I don't even have any more green connectors.

author
snipeyouout (author)2007-08-18

oh ok

author

do you hav any ideas for the arrows for the bow?

author
snipeyouout (author)2007-08-14

try doubling or tripling up the arrows by adding a orange conector

author
Wicky (author)snipeyouout2007-08-16

no you cant....if you do, they either snap, or just get stuck. i tried this many times, but it does not work

author
o.....m......g.....lol! (author)2007-07-16

maybe ill add another half a ft to it

author
o.....m......g.....lol! (author)2007-07-16

author
sportychelseafan (author)2007-06-29

Wicky (author)sportychelseafan2007-06-29

author
sportychelseafan (author)Wicky2007-06-29

author
gibbo_gunner2496 (author)Wicky2007-06-29

ya know its a cool bow n all but if ya seen van helsing you should try and make an auto bow its a wel nice bow

author
Wicky (author)gibbo_gunner24962007-06-29

Yes i saw that movie, pfff that must be impossible to make, 2 and 3 shot bows will work, but i first need a true trigger, that can hold ALOT of tension

author
Pat Sowers (author)2007-06-28

try to make it a compound bow

author
Wicky (author)Pat Sowers2007-06-28

i might make a different bow, that is thinner but more practical. and this already looks a bit like a compound bow, doesn't it?

author
Pat Sowers (author)Wicky2007-06-28

Ya it does, but if it were possible it would be cool to make a functioning compound bow. But I dont care this bow is firkin awesome.

author
Pat Sowers (author)Pat Sowers2007-06-28

this thing looks so cool i wish i had that many parts

author
mmzdaniel (author)2007-06-28

LOOKS COOOOOOOOL!
but im not sure that i can build it, not enough pieces =P
anyways, HEAVY STUFF ROCKS!

author
GreekGuy (author)2007-06-27

-looks insanely cool, but u can always make a simple bow. Nice instructable though!

author
Wicky (author)GreekGuy2007-06-27

Try this, it is pretty effective for its size XD Make a tiny 5 piece bow: Pieces: 2 black/green rods 2 dark grey connectors 1 green connector Add all together to get a bow shaped thing and cut the rubberband once. Then add it to the dark grey connectors Arrow: Pieces: 1 red connector 1 grey rod
