I made a cross bow, it shoots nerf arrows just like a real crossbow. I used a bungee cord for power source.



I still need to make a trigger catch so I don't have ranges yet?

MMMMMMMMMM........More pictures






Any questions or comments?

I know that this won't be very practical in a nerf war. But it is fun to play with. I think I'll launch some tennis balls or something for my dogs to chase.

I made a topic about one of those a year or so ago. I called the topic "Mr. Literal" or something.

Anyway, I recommend using something like a clothespin trigger with a long pin, the pin pressing up against a plate. That way, the catch on the cord can be put against the pin, pull the pin, it ifres.

I used a rubber band gun...

Anyway, that looks nicer than mine. I got ranges of about 45-55ft using an assload of rubberbands. I mean, a fricken'-fracken'-fantastiche amount of rubberbands. That was also with a heavier arrow (screw in the front of a BnA arrow. Yes, the screw was covered).

As far as practicalty, I was able to get a couple shots off in a couple seconds. It was about as fast as my NF to fire, only shot something with more force. I think I may make another one, only out of 1" square tubing and heavy springs on the arms, so as to actually have the arms move. Hmm...people need to stop making me think. That is a very bad thing, when I think that is.

Anyway, nice work. Give it some stain/sealent/oil (WD-40). That'll bring out the colors in the woods.

Oh yeah, you're gonna need a track/rail of some sort so as to get an arow/missile to shoot straight.

My idea for that is to take a piece of pvc and make a long cut on opposite sides of the pipe. This cuts will be for the bungee to go through, and to keep the arrow or other ammo going straight. A pic will explain better (I hope). here Having picture issues, had to link. Anyways, I am not sure what your ammo looks like, so this may not help. Good luck!

blinkycc, you're also going to have to drill out some large areas in the slots in order to let the hooks of the bungees through.


Here's my use of the same concepts.

Whoa, Rennaisance Nerf. Good use of natural resources combined with 21st century plastic technology.

C'mon, pugster. I know those are old pictures. Did you get the trigger done yet? and how does it propel the foam arrows?

I'm afraid if Nerf goes in this direction we'd be looking for catapaults and trebuchets. I already saw the thread for long swords.

Piney, I came all of negatives from falling out of my office cair. That was....many synonyms for 'hilarious'.

I'm afraid of the worst....LARPing technology is sweeping across Nerf at an alarming rate. Everyone, take your clip-fed, spring rifles and you pneumatic farshots and get them ready. We will need as much new-age as possible to counter this. I persona;lly want the battle to be even, so I'll start work on a crossbow and a ballista. Hey....I should make a giant ballista out of angle iron...

Seriously, is there a trigger yet?
