The first K'nex double action revolver, it's only been...oooh... at least 3 years too long since I first made it but over that time I have fiddled and tweaked it to what it is today. So it's finally here YAAAAAAYY!

It can shoot oodammo, blue, green or white rods (I find that I get the most range from the white rods). 
When shot horizontally the range with one band is about 25 feet.


Unlike other K'nex guns with cylinders this one has an auto-revolver mechanism that rotates the cylinder whenever the trigger is pulled, so you never have to rewind it, EVER!



Step 1: Frame

Okay, soooo...

1. Fabricate 1 like so. Merci beaucoup.
2. And a further 1 alikea thiis!
3. Attach these yellow rods and make sure they are in the same places. 

Now set these aside.

4. Make 3 of such a thing.
5. Fix the layers with rods.

Step 2: Trigger, Pawl and the Hammer

'Probably the heaviest trigger pull in the world'  
That is probably true for this gun if you exclude the lovely Nagant 1895 Gas Seal Revolver.
So you have been warned, THIS GUN IS NOT FOR WUSSES it is painful to shoot. But don't fret friends, we shall stay calm, think of home and pull through as we pull back.

Firstly I would like to thank Mepain for inspiring me with his semi-auto pistol-thing (lovin' the Barry White-style voice!).
You should also check out oodalumps' work with semi-automatics (first semi auto-going out on a limb ), semi-auto rifle!
(We'll settle up later for the advertising fee yeah ooda :P)
Also Kinetic's semi-auto rifle looks really cool, I can't wait for that. It even has a horizontal (P90 style) magazine on it.

All, like my revolver, are powered by the energy used in pulling the trigger being rapidly transferred to the projectile (unlike those that use pre-cocked mechanisms ) which reminds me I have an even lower powered (yes that is astonishingly physically possible) full auto pistol I must post instructions for.

Oh yes, we are supposed to be building, anyhoo.

1. Trigger.  Make Odeen  (that is one in Russian. See if there is a gun learning is always more fun!)
The placement is correct in the photo and no, this cannot be replaced by red connectors, the rod pops out from the bending moment.
 Now make the trigger so it can be depressed without pliers, this is how I like it, you can tinker around to see what you prefer, but this is the strongest method I have found.

2. Like on most (nearly all modern) revolvers (excluding the Webley-Fosbery self-cocking revolver ) the pawl is what rotates the cylinder to the correct position so as to line up the hammer with a fresh round.
So, just make one of these, simple as.

3. Hammer. As the name suggests this is what will smash into the back of the rod in an attempt to propel it.
So take 3 white connectors bash in a white rod to hold it together.
4. Make this.
5-8. Attach it all together.

Step 3: Cylinder

1&2. Make 8 of these chambers (6 Lt grey connectors on a blue rod) - note the placement of the 2 attached at a different angle, we shall call these 'Pedro'.
3. Make 2 if you will.
4. Now pop all of your 8 little lovelies on to the 2 discs as shown.

Oooh remember that the inner side of the cylinder is the one with the Pedro 1 connector in.

5. Now that the base is made put a white rod in all 8 tubes (I know they aren't all white but then variety is the spice of life)

6. Tada!

Step 4: Indexer

You know when you hear the rattle as the gunslinger spins the cylinder on his Peacemaker .45? Well, that is the sound of the pawl and the little indexer that ensures proper hammer-cylinder-barrel alignment.

1&2. Construct the indexer. (Make sure the tan clips are pointing the same way as the Lt Grey Connector)

3.. Make 4.
4. Make Odeen (1). We're learning!!
5. And odeen again.

6. Now stick 'em all on here won't you good ol' chap!  Would you be so kind as to clip them all to a yellow rod as well.
 

Step 5: Assembly!!!

Now we've got all these bits we can stick 'em all together.

1. Push a grey spacer (or 3 blue spacers) on this rod)
2. Put the hammer on too and add another grey spacer.

3. Push a grey spacer (or 3 blue spacers) on this rod) - this seems familiar *shifty eyes*
4. Slide on the trigger.
5. Now put another grey spacer on the rod.

6. Add the thickness of 6 connectors in spacers (12 blues, 4 silvers) onto the yellow rod by the hammer.
7. Put the pieces on the yellow rod above the trigger like so, this time the order is important. The space to the left of the photos is also necessary.

9. Slip the pawl on to the trigger.
 
 QUICK! WE DON'T HAVE MUCH TIME!
Before the pawl falls off attach the other frame panel.

Step 6: Assembly, Part 2 - Electric Boogaloo

1. Grab your frame bit from way back in step one and attach it to the red connectors in the precise position shown. I WILL NOT ACCEPT DEVIATION!!! 

2. Get out a yellow rod and slide it through the cylinder, then put on another white connector and a blue spacer.
3. Spin that baby round and push on 2 grey spacers (6 blues), you may be able to see that I have wrapped an elastic band around the rod as a shock absorber.

4. Attach this to the middle connector.
5. ...and to the green connector here.

The Return of the Indexer

6. Clip on these grey connectors.
7. Put the indexer on like so.
8. then seal with a red connector.

Step 7: Band Placement.

..and that's the way you do it.
Near the barrel
I mean just has a band that acts as a damper
How doesn't it rotate
<p>HORRIBLE INSTRUCTIONS!!!</p>
<p>It has a pawl which pushes the barrels round</p>
can you ppppllllllleeeeaase tel me how the barrel rotates
AMAZING GUN but carp instructions
dude, this is awesome. I am definitely making this 5*!
What is the max amount of bands you can put on this thing?
It depends, if they were #64s then 2 probably.
PLZ REMAKE INSTRUCTIONS
HELP OMG when i shoot it it only goes back like an 1/8 of the way and the trigger is touching the barrel Help!!!!!!!
hmmm... if you ask me, it looks a little too much like oodalumps's WASP to be credible.
Are you so illiterate that you didn't read the intro?
how the turret rotate
I think literacy is not the problem here.
its impossible!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
WTF DUDE there was already no blue spacers
What the hell <br>Pic 4 Fail
i dont have this orange connector !!
Its that okey if i use my turret TR18
man its like a automatic TR8
This gun is great.... but the instruction is by far the worst i've ever seen.... <br> <br>for example look to picture 1 from step 2 ( look where the straight orange connecter is placed with the white rod) <br>Now look to picture 4 and 5 from step 5 ( is it on another place.... you didn't even say that it sits wrong or something ) <br> <br>That's why i don't realy like the instruction... I'm realy sorry man <br> <br>I rated: 4.5 ( for gun ) 1.5 ( instruction) 4.5+1.5=6 6:2=3 <br>I rated a 3... i'm realy sorry man just not very nice to build if it takes you like 5 minutes each picture to understand.... <br> <br>
I want to see how it works (the rotating mechanism) But you have GOT to make better instructions!
BWAAHHH NOT ENOUGH LIGHT GREY, GRRRR.
replace them with reds, works for me
Haha, thanks for the help but i got more pieces.<br>
ok
dude its an awesome gun but can you please make a better instructable because i realy want to make it
Terrible instructions!
this gun is AWSOME!!!
Cool gun :) Horrible instructable :(
:( It took me 2 days to do that.
Well I can tell you put effort into it based on all the extra comments (you have a good sense of humor), but on some of the steps you showed images of an already complete gun and when putting the gun together you would jump from a half completed handle to adding a forgotten spacer. When I post guns, I do it layer by layer, though I recognize that that is a little more irritating with a yellow-width gun, but it is much more clear. I love the gun, I the effort you put into the instructable, but try to follow a layer by layer format next time and you won't hear any complaints from me :) Sorry if I was a bit to the point on my first comment.
Well thank you for telling me, constructive criticism is always appreciated.
Ya, we never made that stuff in pic 4!
My rating changed your overall into a 5.0 (:
What do you mean you can't read the photos?
well i cant really understand where to put the bands and other things
If you understand how this mechanism works, you should know where to place bands that provide the mechanical energy for such a thing to operate. :p
whats up with pic 4, we never made that! =/
Not on KI :'( It shoots pretty far though.
dude its sweet but it dosent shoot very far
Sorry dude I tried making it but the instructions are too unclear. The idea is very good though.
Good idea, but due to inconsistent directions, lack of English, and extra/unrelated pictures, the final result left me with a broken orange connector, three barrels that fell off, two bullets that actually shot, and three barrels with the bullets about a millimeter from their original starting point. I am really glad I got to take apart my M1 Garand Hammer Mech gun for this.<br><br>NOT.
Alright, that was a bit harsh, and the broken piece wasn't entirely your fault, but when you said to put the rubber band somewhere instead of showing us, it got really messed up, and the only reason the above happened was because it wouldn't spin. The times it did it shot very nicely.<br><br>Please add a little bit more detail, clean up the pics so that you don't have extras, and please be more consistent with the pics, for example, in Step 1 below the snowflake connector it is a green connector, yet in the final pictures it is a yellow connector.<br><br>A video would bring my 2.0 up to a 3.5 or above, with one of the plates removed, preferably the one with the pawl on it removed so the mechanism can be seen and duplicated, thank you.
Okay, yeah, I will try to do a video. Sorry about some inconsistency in the photos, it was because as I was doing the Instructable I modified it slightly.
And thanks for being cool dude, as you know, comments always look more hostile than the person intended, but I modded it to shoot yellow rods with a break-action type thing where the handle part bends in the middle so you can easily take the cylinder out to reload. Yeah, I mean, I know how it's SUPPOSED to work, for me it just doesn't. Thanks man for replying though.
Alright, I mean, I modded it so now it just doesn't rotate, part of it was my fault I think, so I'll higher the rating, but I would really like an auto rotate... Like I said, a video of the mechanism (the pawl-side plate taken off) would suffice, but it DOES get nice range. Reminds me of the Mauler from Halo haha.
these instructions are retarted in every step its got something from a previous step but a peice is different so you have to change it <br>
