Introduction: T.K.B.T (The Knex Bear Trap)

Picture of T.K.B.T (The Knex Bear Trap)

Check My Tornado 480 Command V2 too!

This is my latest creation and actaully a very simple one.
Basically, the claw grabs something that hits the blue rod and it just puts it's teeth into it... and hard!

-fun to use
-can trap anything (even my walking-robot)
-a chain so the target can't move
-it keeps it's mouth closed when hit

-might bite and close when you're setting it

For short:
It's a recommandable Bear Trap.

Update on the Tornado:
It is Posted!!!

Step 1: The Ring

Picture of The Ring

This part is for a sturdy bodyframe.

Step 2: The Pole Ring

Picture of The Pole Ring

This part is to lock it around something like a tree.

Step 3: The Chain

Picture of The Chain

this part is to keep the Trap Ring and the Pole Ring together.

Step 4: The Emplacer

Picture of The Emplacer

This part is to keep the trap opened until someone or something hits it.

Step 5: The Actual Trap

Picture of The Actual Trap

the Rings and the Chain are actually not required (but they make it look nicer), you only need the actual Trap and the Emplacer.

Step 6: Assembly

The pictures speak for themselves:

If you have any problems, post a comment on my orangeboard.

Step 7: The Tricky Bit

Picture of The Tricky Bit

This part is kinda tricky and will require some stable fingers.
you need to disconnect the yellow rods so the trap is set.
here, 2 pics on how it should look.

pic 1 connected, pic 2 disconnected.

Are you acting brittish??????

Snosageman99 (author)2011-09-24

In the emplacer step does the blue rod with the grey clip attached to anything underneath???

K.G.T. (author)2011-05-29

Easy to deactivate, like all bear traps. Someone throws something on it, it snaps shut and is deactivated.

Skreetsha (author)K.G.T.2011-06-06

And that's a bad thing?

K.G.T. (author)Skreetsha2011-06-27

No, I'm just saying. Your version might actually work. When I try it it takes a kick to trap anything. I just want to catc my cat. The cat broke my K'nex Cage.

Skreetsha (author)K.G.T.2011-06-30

Lol, you might have a chance, but no succes guarenteed :P

Dumchicken (author)2011-01-15

Skreetsha (author)Dumchicken2011-01-16

If you hit the pin it should close if set properly.

dnmonsen (author)2010-06-19

Skreetsha (author)dnmonsen2010-06-20

Go to my Youtube account and search Viccie.B1993's Knex Creations.

arf200 (author)Skreetsha2009-07-22

wtf! sharpened knex are iligal in Holland

Skreetsha (author)arf2002009-07-22

No, having a lethal weapon in your home, is illegal in Holland, not sharpening K'nex. LOL.

DJ Radio (author)Skreetsha2009-07-22

they only kill you if it hits your neck or something.

Skreetsha (author)DJ Radio2009-07-23

Yeah, but that makes it lethal, right? You just have to aim a bit more precise. Lol.

psharpep (author)Skreetsha2009-11-26

Well if you're stupid enough to get hit with a bear trap in the neck you kinda deserve to die... helping humanity lol

An Villain (author)psharpep2010-05-03

*flops over*

pie25x (author)An Villain2010-06-06

Lol. And how exactly does he flop over? Wouldn't it be a coincidence that the bear trap is near?

An Villain (author)pie25x2010-06-07

Trips over something?

dnmonsen (author)An Villain2010-06-19

how about a person laying on the ground the bear trips over him the man dies and the bear falls in the trap and dies too.

An Villain (author)dnmonsen2010-06-19

Bears don't "trip" very well.
