How to Make the KTP (K'nex Twin Pistol)

Intro: How to Make the KTP (K'nex Twin Pistol)

KTP is a dual barrel knex pistol, that has 3 firing modes:
Semi auto (Strong)
Dual shot (Stronger)
or Single shot (Strongest)

I built it as a sidearm, and it works great.
You can easily turn it into a rifle,
but I didn't have enough knex to add a longer barrel or a stock.

The single shot can put a quarter inch dent in drywall!
It help if you tape the ammo though....

Its semi auto mode isn't quite true semi auto, but it fires at the same rate as one.
You see, it has two triggers, side by side...

Let's get building!

and credit to DJ Radio for the inspiration

(Single and dual shot mode shown in pics)

STEP 1: Barrel Part One

This is the back end of the barrel.

1. Build four of these.

2. Clip them onto a yellow rod.

3. Build this.

4. Put them together here.

5.What you should have

The yellow rod might slide out, but just keep it there for now.

STEP 2: Barrel Part Two

This is the front end of the barrel.

1. Build these. The color of the pieces doesn't matter.....

2/3/4: Connect them onto a yellow rod then clip a blue rod on the other end.

STEP 3: Completing the Barrel

You now need to connect the two together!

1. Clip the yellow rod and onto the snowflakes, and a blue rod onto the yellows.

2. Build ten of these.....

3/4 .Clip them on like so... 3 on one side, 2 on the other.

5. Do the same here.....

Now put this aside, and lets work on the handle!

STEP 4: The Layers

The gun consists of several layers.

1. Build/get all of these.

2/3.Put them in this order

4. Clip them together here.

STEP 5: The Handle and Triggers

1. Put one of the little white rods with a tan lock on it in with the two snowflakes. The white rod will hold them in place.

2. Add a blue rod to hold it together.

3. Add a tan lock and white rod in with the triggers....

4. What you should have after you add another blue rod.

STEP 6: Connect the Barrel to the Handle

1. This will be easier if you take the white rods out. Slide a blue rod through the greys, then add a yellow connector.

2-5. Clip the blue rod onto the other yellow connectors, and the other blue rods onto the snowflakes.

6. Put the green rods back in.

STEP 7: Trigger

This is the trigger.
Pretty simple:
Get two gray connectors, put y connector on each one,
the clip them onto a blue rod. Thread a long elastic through them....
Clip it onto the two triggers.

STEP 8: Loading and Firing.

This is what you need to do to fire it:
For single shot or dual shot, you need:
Rubberbands
Either one rod with an orange connector on the end,
or two L ammos.


Put the rubber bands on like so,
then put the ammo in as shown.




If you want to fire in semi auto mode, you need to do a few more things:
Take the blue rod and grays off the triggers.
Put white rods on.
Put the blue rod behind the whites.

Then load the ammo and put the elastics on like shown.




Oh, and here are some pics of my rifle, that uses the same system. It's just bigger......

I dont exactly get this step, still Strugglin!

[knexaddict]

I got it, made a Few Errors!

[Bartboy]

Hope it works great!

What could make the instruction clearer?

[Knexman15]

clear instrunctions i will build it when i can great job

[Bartboy]

Thanks, it's definitely my best instructable.
If you build using yellow rods instead of the blue ones, (Like in my rifle), it will be much stronger. But be sure to increase the barrel by two or three connectors for maximum range!

[skyfaller]

IS this worth taking apart everything youve made out of knex?

Because its tempting to take apart my two way kex sniper/rifle.

[Bartboy]

Yes, but I HIGHLY recommend adding a few barrel extensions to it.

[skyfaller]

I took my gun apart, built it, Just to find out that before completing the gun, i ran out of orange connectors.

[Bartboy]

:( That sucks.... But you can substitute other things for all of them except in the barrel!

[skyfaller]

Still not enough D:

[mettaurlover]

Simple yet effective.

[Bartboy]

Thanks, it's a pretty generic double barrel idea, but I think I was the first person to actually make it. If you do build it, I recommend adding some sections to the front. If you add top and bottom sections, then you can basically put as many elastics as you have on it without it breaking. And it shoots far too...

[mettaurlover]

This is basically like my gun, but without the guide rails for most of the barrel length if I made it longer. ATM, my pieces are busy being in the D-TAB which I need to find the pieces to build the turrets for...

[M4A1DrumRoll]

 I now know what i want for xmas... more Knexs

[DJ Radio]

Now I have absolutely no reason to keep my first posted gun up. If anyone just begs me to put it back up, I will just link em here.

[Millawi Legend]

Was your first Ible your SPEC-9?

[DJ Radio]

My first knex ible.

[Wafflicious]

I actually think I'll build this....5*

[Bartboy]

Thanks! Good for mini-wars, and it takes about 3 min to build.

[Wafflicious]

do you want to see mine? I made it a rbg sniper.
