Introduction: 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.

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:

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

author
DucttapeNinja made it!(author)2009-12-06

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.

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

author
DucttapeNinja made it!(author)2010-01-06

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.

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!!!
