Introduction: K'nex UMP-45 Redone

Mkay, sorry, but I still couldn't be bothered to get a full instructable. It's silly though that this is pretty easy for an experienced builder, so I got quite a few pics that should easily help you figure it out. Anyone is allowed to post it without permission as long as they obviously credit me, and a notification would be nice too.

Anyways, I'm warning you now that this gun uses a few broken pieces and has hideous range. You could modify the gun to accept a normal pin instead of the charging handle-like pin I made but I didn't bother trying to myself. The back sight was crudely thrown together as it's too large, as is the front sight really. It lacks a top rail (as if it was useful) but still has a bottom rail and can still use the generic forehandle. Lastly, it lacks a stock. Overall, I'm just hoping someone can build and modify this for me, then post it.

1. Whole gun. Looks purty, dun it?
2. Top of magazine, pointing out broken pieces. The front one is actually clipped down a little. If you really want, you could probably get away without these with some modifications that I didn't want to bother doing.
3. Here's the side ripped open and the handle area.
4. Another side view on the back.
5. A side open view on the front.
6. The inner side layer ripped off revealing the middle layers in the back.
7. And ditto for the front.
8. Finally, the inner and outer right side layers for the back.
9. And for the front.

I'll add notes where necessary.

I dislike the idea of the mag using broken pieces; I much liked the idea of the old one, with the locking blue piece.

I much like the new barrel compared to the old, as well as the handle. Overall, the design is much sleeker, which is a plus, given your old one.

Yeah, I really try to avoid broken pieces when possible, but I just happen to have a lot of broken oranges from building, so I figure it's not to uncommon for others to have them too. If I ever remake the gun again, I'll try to use only normal pieces.

And thanks. I've always thought about improving it further, but I want it to be a big improvement.

You should add a stock.....but it looks nice

TheDunkis made it! (author)TheDunkis2013-07-05

At the time I didn't have enough pieces for a stock. I may consider rebuilding this and adding one some time in the future.

This is a very great gun. The only problem is that the band makes the pin fly out no matter where i put it. i put the green rod where you suggested it, but it still comes out.

Curses. I lack the skill required. Still a nice replica.

Purty. If I find the time, I might build it.

You need to use a higher resolution camera for the next ible.

author
TheDunkis made it! (author)TheDunkis2011-07-12

I was using my 3DS because it's easy to upload straight to facebook and then get on the computer to transfer it to ibles. I don't know where my other cameras are at. I'll try my iPhone next time.

tytiger33 made it! (author)tytiger332011-07-13

So the earlier pics were taken with your DSI? That explains the low resolution! But really please use a real camera or the IPhone with some sort of stand or tripod so the picture is less blurry and so we can zoom in to see fine details. If you had used a real camera or a good phone camera we might have been able to build the TBAG.

TheDunkis made it! (author)TheDunkis2011-07-13

I'm not an image noob, I know! Again, I used my 3DS's camera because it's easy to upload with. My digital camera is lost in the piles of junk my parents like to make while cleaning. But I just got an iPhone for my birthday which also makes uploading easier with so I'll start using that.

But I will say one thing that has sort of become a motto for experienced builders: You're not doing us a favor by building our creations, we're doing you a favor by providing any instructions at all. Anywho, any forums I make are of weapons I don't plan on people building until I get instructions unless I clearly state that I have no intentions of making instructions myself. For example, the TBAG had a flaw in the back of the barrel. I didn't want more people complaining about what didn't work so I didn't get any more pics of it.

And I don't mean that yours is a 50*50 bit pic it's just not good enough to make the gun from.

author
tytiger33 made it! (author)tytiger332011-07-13

I know we aren't doing you a favor by building your creations It's just nice to be able to build them even if the have a flaw. It keeps us tested and on our toes to do so. It's just good practice. But if you made a 50*50 bit picture of a knex gun you don't get enough detail to make it. It's just that simple. And about the piles of stuff I have the same problems with the cleaning but they put it in paper bags but my parents keep the 1000$ DSLR downstairs in a cabinet in the living room. I suppose you have a place where you keep your old game-boys and other electronic you rarely use so just put the camera there when you find it. If not just put the camera on a window sill in your room with the charger or in your closet for storage and put your electronic charging station in your bath room (that's what I do) And by piles do you mean 5 ft mounds or short ones?

if the pin goes into the stock when pulled back, you cant have a folding stock.

author
DJ Radio made it! (author)DJ Radio2011-06-30

Maybe make the stock fold only when the pin is not pulled back. When it is the stock is locked and cannot change position.

author
TheDunkis made it! (author)TheDunkis2011-05-27

You sure you won't be able to figure out something? It's just one little gap you'd have to make at the top of the stock.

The range isn't too bad. Average for a Knex SMG.
30-40 ft.

Whats the range? ill retry it and try to addapt rec0ns folding stock idea, along with a top rail.

Bad. Though when it is converted to a standard mech,, the new barrel design with y clips is quite efficient. Feel free to make it as it is, but I recommend converting it.

full auto or semi and what's the mag capacity?

author
TheDunkis made it! (author)TheDunkis2011-05-22

Neither, it's a repeater. And I'm not sure. I'd guess 12 rounds about.

author
a_person made it! (author)a_person2011-05-23

Oh so you mean the fire mode is you have to pull the pin back for every shot?

author
TheDunkis made it! (author)TheDunkis2011-05-23

Exactly. Most K'nex weapons have to be cocked every shot. Any guns that are automatic have poor range or come with some other kind of huge quirk.

built it but my pin comes out every shot almost...

author
TheDunkis made it! (author)TheDunkis2011-05-14

Add a green rod to the yellow connector in front of the pin. It should shorten it just enough that the pin won't fly out.

author
The Nomlack made it! (author)2011-05-11

at pic 7, for the fake barrel is the white rod cut? it looks cut to me

author
TheDunkis made it! (author)TheDunkis2011-05-12

Oh, no, you connect the black hand to the end of the rod. Look at my Oodassault 3.6 instructable to see an example.

author
The Nomlack made it! (author)The Nomlack2011-05-12

oh thanks! i finished it and its great! but the trigger keeps getting caught by the handle

author
TheDunkis made it! (author)TheDunkis2011-05-12

Ah, that's another part I forgot to note in the pictures. Did you use a black hand to separate the handle sides at the front connection? You have to connect it so it the nub faces toward the back connection of the handle. This'll allow the trigger to slide through without problems. Otherwise I don't know. Anywho, good luck and have fun with it.

Epicness :D Will get round to doing this after exams! I might use the shotgun'#s rail and charging handle to improve it.

author
TheDunkis made it! (author)TheDunkis2011-05-10

Charging handle? What, make it protrude from both sides? Go for it if you want, I made it this way for realism. If you could, mod it in anyway that still keeps it realistic (rails I have no problem with, a stock, even if crude, would be nice) and then post it, that'd be excellent.
