Introduction: The Shrapnel Spreader K.T.B (Knex Time Bomb)

Picture of The Shrapnel Spreader K.T.B (Knex Time Bomb)

Check my Sipriani Rifle too!

This is the first ever knex time bomb on the site!
It has a range of 3.5 ft.
The timer is about 22 seconds with two 64# rubberbands tied together.

-strong bottom
-block trigger system
-pretty good range
-can keep up to 23 white rods in the spreader
-uses a firing pin

-spreader isn't strongly attached to the bottom

For short:
It's a recommandable time bomb.

If you have any questions or problems please contact me on my orangeboard.

Step 1: The Trigger Stopper

This part is for stopping the trigger from blowing the spreader of the top.

Step 2: The Timer

Picture of The Timer

you can make the wire as long as you want
one 64# rubberband is 6 to 8 seconds on the timer.

Step 3: Bottom (stand)

This part is the support for the spreader.

The engine is the blue one out the Starburst Spinner Set.

Step 4: The Spreader

this part is required since it holds the white rods that need to be shot.

Step 5: Trigger Track

Picture of Trigger Track

This part is for letting the trigger go straight so it won't pull the trigger in a weird direction making the trigger shoot away.

Step 6: Putting Together

Skreetsha (author)deawon22009-07-30

Nee, da's om het elastiekje op de as te houde zodat hij er niet vanaf glijdt. :P

deawon2 (author)Skreetsha2009-07-30

oh ja en dat probleem dat het niet goed aan het ondersteuningsplatform vasthangt heb ik een oplossing nl: 1 de 4 (2 aan elke kant) bovenste gele connectors vervangen met witte 2 oranje connectors aan de spreader op de blauwe staafjes juist naast degene die al vastzit aan het ondersteunigsplatform 3 zoeken welk staafje tussen de oranje en gele connectors past 4 opgelost!

deawon2 (author)Skreetsha2009-07-30

euh kweenie hoor maar zit het elastiekje niet aan die grijze connector vast?

ghostpotato (author)2011-12-03

how is a block trigger system a good thing ????
(its in the pros)

Skreetsha (author)ghostpotato2011-12-10

It's not a gun. We all hate block triggers but let's be honest. It's a very reliable mechanism

D1rty Di3sel (author)2010-03-16

will the black motor work?

ghostpotato (author)D1rty Di3sel2011-12-03


Snosageman99 (author)2011-10-06

So let me get this straight....basically the motor turns the wheel and the rubberbands are connected to the wheel. So when the motor turns, the rubberband gets pulled and when it reaches a certain strength the rubberband pulls on the block trigger and fires the I correct?

Skreetsha (author)Snosageman992011-10-25

Very. Lol

Snosageman99 (author)Skreetsha2011-10-25

I buit like 10 of these and made a mechanism that turned all the motors on tat the same time and i suprised my sis by showing her the creation and telling her that it created energy so when i turned the switch all the bullets fired at her....sadly they all missed :(..............................................but still 9999999999999999999999999999999999999999999999999999999999999999999999999999999
