This is how to make a functional lego bow and arrow. First you'll need a lego tube tube, scissors or a knife, lego stick, and a rubberband. Please try it before you rate it because it works really good.
About this creation
First get the lego tube. There is a tube like the one I used that is very similar but different. The one I'm using is more stiff and doesn't bend as much. The other one bends alot because it is rubber. The one were using is plastic.
Then cut it into a shaft. You can cut any size you want.
Then you need to make a curve for it. If your making a recurve shape, then you might want to cut a bigger shaft from the tube, because the recurve shape will take away much of the shaft's length. Also recurve are harder, so it's best that you just give it a longbow shape.
Then get a rubber band, cut it, then tie to the bow. The rubber band's length is all depending on the size of your bow. If you're making it for a minifig, then you should use the yellow or red lego rubberbands. The length of a lego rubberband can be deterined by the color. Now if you've done all this you have your bow, to shoot it just get any lego stick and shoot it like any other bow.
With some extra attachments you can make a crossbow. for this one you lock the rubberband behind the piece with a hole in it, put the lego stick through the hole, attach it to the rubberban, grip the rubberband to the stick, then pull back and fire.
Very good. People are always amazed with the really huge and detailed models, and they think it takes so much skill to build them. But they forget that it takes just as much or more skill to make your models small and compact. I really like this one because its so darn cute! I also like how you can convert it into a crossbow. Great work, keep it up!
