Introduction: Hidden Crossbow

Picture of Hidden Crossbow

     Looks like a crossbow, but technically it's a slingshot. I saw instructions for a BIC pen "Bow and Arrow" on the site and decided to step it up a notch.
     This contraption is made to be worn under a loose sleeve, hidden from sight. It shoots the ink cartridge of a ball-point pen. The trigger (a clothespin) is rigged to fire when I flick my wrist back.

The instructable is now up! You can find it here.

This thing is absolutely amazing although it took me around two hours to make but easy to do when your watching a boring movie.

Just a suggestion: you could use a duct tape sleeve instead of a Popsicle stick one so its comfortable.

A lot of people are using drawer slides. I myself am looking for a good small one.

Here's a good example:

JamesHawke (author)DucttapeNinja2010-05-02

I'll see if I can try

Plo Koon (author)2011-04-25

I like ur username.

LiftAndLove (author)Plo Koon2011-07-27

Admiral Blaze (author)2010-04-16

 eh its ok but its only a cross bow ive made an airsoft hidden pistole thats about 250 fps, im making an instructable for and it will be up in about a week

Ooh, looking forward to seeing that!
Personally, though, I have a certain admiration for the more archaic weapons.

that thing is pretty cool though i think i might make one, as for the airsoft ive made three differnt models and the first one is only the prototype

ztaffa (author)2010-02-17

Plz post an instructable i wanna make this so badly

DucttapeNinja (author)ztaffa2010-02-17

Here ya go.

ztaffa (author)DucttapeNinja2010-02-23

thanks i didnt see that

lycoris3 (author)2010-02-08

indeed t'is wonderful in mind

Koonboi (author)2009-12-05

How can you post this without instructions?

DucttapeNinja (author)Koonboi2009-12-06

Yeah, sorry. I made this about a year ago, so I don't have pictures. Once finals are over I can start working on one to post.

wangtrevor (author)DucttapeNinja2010-01-03

can u post how to trigger mechanism works and just how to build the trigger

DucttapeNinja (author)wangtrevor2010-01-06

It's pretty much just a clothespin with a hole drilled through the ends you pinch together. Tie a strong string onto one side and thread it through the hole in the other. When the string is pulled, it should bring the two parts together.

The end that is held closed by the spring is what holds the rubber band back, so the strength of the clothespin directly affects the tension you can have in the band. The rubber band is looped through a special catch that fits into the clothespin, so the rubber band is not directly pinched by it.

I hope that helps until I can post the whole thing.

Koonboi (author)DucttapeNinja2010-01-06

That helps a lot. Thank you.

Arbitror (author)Koonboi2009-12-15

Simple, as a slideshow...

Arbitror (author)2009-12-15

Wow! It's just like Altair's secret blade, only as a projectile!

watzhisface (author)Arbitror2009-12-30

like ezios thingy

watzhisface (author)2009-12-30

can u post an instructable on it

RedneckAsian (author)2009-12-04

If you replace the ammo with a blade that doesnt launch, rather just stick out when fired, and widened the launcher, it could be like Jigsaw's arm blade in the first Saw. Please post instructions!!!

bowmaster (author)RedneckAsian2009-12-04

I was thinking Assassins Creed.

RedneckAsian (author)bowmaster2009-12-16

Yeah that too.

bowmaster (author)RedneckAsian2009-12-17

Assassins Creed is a million times cooler.
