Introduction: DOTR8 (My Custom TR8)

Picture of DOTR8 (My Custom TR8)

I've been experimenting with making my own turrets for a while, and I think I've finally found a way to build one differently from the original that gives it some advantages.  

These are the instructions to build it.

Anyways, some of the advantages are that it:
Is sturdier than the original TR8.
Doesn't use an abundance of two-slot grey connectors.
Is really pleasing geometrically to build.  (I could just stare at the internals of the turret for hours. :3)
Is compatible with all the other TR8's.
Get the exact same range as a regular TR8.

I would recommend this to anyone who wants to have a turret that is different.  Mount this on your Turret Rifle today!

Take note that 4-slot green connectors don't have to be used for the majority of the barrels; you can also use red 3-slot connectors, or anything that has more than two slots, but no larger than a five-slot connector.

I'm working on a turret pistol that will use this turret.  So far, I have only posted pictures of it here.  Keep it quiet, though. :3

Step 1: The Parts

Picture of The Parts

Here are all of the pieces  that you will need to build this turret.

Part Count:


Green Four Slot Connectors: 40 (Can be substituted with Red Three Slot Connectors or even Yellow Five-slot Connectors)
Red Three Slot Connectors: 8
Orange Two Slot Connectors: 8
White Eight Slot Connectors: 5
Tan and/ or blue clips: 8 (You just have to have eight little nubs; it doesn't matter which kind; they can be mixed or all of one type.)


Green Rods: 40
Blue Rods: 8
White Rods: 8

Keep in mind that it's possible to substitute many things for this turret.  If you don't have enough pieces: experiment!

Step 2: The First Layers

In these steps, you'll build the energy transfer or mini firing pin thingy and give the turret structural support in the back.  

When you're done with this step, you should just stare at it for a bit.  That spiral pattern looks pretty cool, doesn't it.

Step 3: The Next Layers

Now you'll build the barrel that leads up to the bullet lock.  Just follow the pictures, and if you have any questions, please ask.

Step 4: The Last Layers

Here you will build the bullet lock and finish the turret's front.  I hope this turret serves you well!

Makes a good bowling ball :D

I'm glad it went to good use. :3 It works best for guns, though.

Thanks. I see that you're viewing all my instructables right now. :P

Then you probably didn't know that I'm just back from 2 weeks vacation =D
I'm now watching all new knex stuff, so I'm also watching your work (and I like your work :D)

No, I didn't know that (but I was wondering where you went). :P And thanks!

Your ball machines are absolutely amazing, by they way. I would try to get into that, but I don't think that I have enough pieces. :I

That's the biggest problem for knex builders: parts. I don't know how many parts you have but for a normal size ball machine you need at least 7 - 10 thousand pieces.

And that's where my problem lies. :I

You can try to build only lifts and then post instructions if it's a new concept.

Oh, maybe I'll do that sometime. :P No idea where to start, but I could try.

Oh, and although I don't usually keep track, you are my 600th comment. :P Congratulations and thanks!

Haha no problem! You just made my 1243rd comment :D

Awesome! Thanks for the vote, too. :P

And I voted :p

Well that is nice to know thanks once again!

You're welcome, and I forgot to mention it, but I like your profile picture. Derpity derp derp derp.

Xx2draktastik7xX (author)2013-07-27


You're welcome; I posted this so people could use it! :D

Dude this is awesome do you mind if I use this turret "mag" in a turret gun ?

No, by all means, go ahead. :D It's really just a modified version of a TR8.

I wouldn't say my costum because people have posted it on instructables already

It's actually built a bit differently from all of the others. Notice that the blue rod is on a different peg than it is normally, and that the internals are quite different. That's why I consider it 'my custom,' but I can totally see the reason for the confusion. Thanks for the advice, though!

ok it just looked similler

Yeah, it sort of does; I can totally see why you thought I was some noob saying that I 'invented' the TR8.

lol well at least you found out that you didn't make the tr8

No, I knew I didn't make the TR8, but whatever... It's cool. :D

Thanks. I was kind of bored one day, and I had this lying on my turret pistol Scorpio which can be found here.  I just kind of dismounted it, went up to my room, disassembled it, and made instructions.  It was a nice way to kill an hour or two. (I don't remember how long it took me.)

didexo (author)2013-07-19

Meh, to flashy for me :)

Yeah, I kind of tried to make this thing look a bit flashy. If it's not your thing, that's cool. :3

Flashy isn't really my thing. I'm a fan of keeping things simple :).

Whatever works for you, dude. >:C

DarkOwlProductions (author)2013-07-20

Thanks. :3 I've got just the gun in mind for this beauty. Actually, it's already built; I'm going to make a slideshow and, possibly, maybe, don't hold me to it... instructions.

That is really nice bro. I really like this. =D

Thanks! The best thing about this for me is that spiral you make in the first step. I had a friend over (yes, it was the friend that did the hand modeling :3) and we had a conversation that went like this:

Me: Hey, look at that spiral.

Friend: (Glances over) Woah, it's like, so cool looking.

Me: I just love when K'nex works out like this.

Friend: Yeah, I love those moments.

Me: Those moments don't happen very often, do they?

Friend: No, not really...

We then proceeded to stare at it for about a minute or two before going back to watching youtube videos on the computer. :3

Sounds fun...

But I've been in the same position myself... About the youtube videos with a friend I mean... :P

Yes... That was before I discovered Nerf... Ahh... Memories... Matter of fact I'm having target practice with my Triad right now!

Cool. :3 By triad, you mean a group of three, right?

No! I mean my newest Nerf gun! The Triad! I just got it today and I'm target practicing with it! I always do that with my new guns. Nerf war tactics! ;)

nerfrocketeer (author)2013-07-19

Looks pretty cool! I still have no skill whatsoever with K'nex guns... But I might make something with it at some point... :)

No, you have skill at building; all you need is a little more practice! Thanks!

I guess... :)
