Oodassault 3.7 Answered

Yeah, I've done this too much. 3 different models, 7 revisions for this model alone, 2 already posted.
The 3.6 was satisfactory but I noticed there were still some problems for some people and it required some tweaking to make sure it worked right even though it was pretty reliable when it was set up right. This one is a lot more user friendly. I changed up some things so it's guaranteed to work without all the tweaking. It was just a few minor mods really. You won't probably catch any changes from the image alone at first so I'm obviously going to list them.
-The simplest but probably most effective is adding another light grey in the middle above the magazine. At first I had a gap there to make stripper clip loading easier. However, it made the ammo shoot up a little higher and sometimes would cause it to spin out faster. I also suspect this may have been the reason a second round would be dragged out if the magazine wasn't set up right.
-There's a green rod and spacer wedged in between the bottom of the magazine where the tilt bands are placed so that it doesn't squish the mag pusher. This allows for a weaker rubber band on the pusher so there's less chance of it exploding.
-I changed how the the magazine rests against the rest of the gun by using mini knex adapters. I'm not sure if this is required as far as reliability goes but I suspect that it may have been why some people's guide rods were shot off. The magazine tilted in ever so slightly but just enough for the ammo to catch the rod. The mini K'nex also have a larger gap so it's a little easier to slide ammo in. Not too much of a difference but hey, whatever works.
-The one you guys probably will like best. I changed the tilter just a little. It requires a rubber band to stay up but I didn't think it was a big deal. It allows the magazine to tilt out farther and the red connector can grip around an orange connector on the trigger guard in such a way that it takes some of the stress off your finger. This means you can use more tension on the magazine to make sure it stays shut without wearing out your finger.
-Finally, I knew this for a bit but decided I'd finally show you that you can use green rods instead of white rods on the top middle three holes (the bottom pairs and the front and back pairs would be required to keep the gun sturdy). You can use green rods then instead of black Ys to block the green rods in the holes. I used this method for a simple rail like thingy and added a custom sight. It's more for looks than function but it actually works quite well.

So yeah that's it. Between all the mods, it's guaranteed to work perfectly now as far as I know. Nothing has gone wrong since building the gun with everything changed. No magazine explosions, double shots, or anything that would otherwise be undesirable. Also, it's a little more accurate and gets a bit more range I'm guessing thanks to slightly more stable ammo.

I'm not trying to make this sound super hyped. You should just know that I come from a long line of descendants whose ancestors built the Great Wall of China.

so wait, if i make this is it going to be 100% reliable?

More like 99.99999999999999999999999999999999999999999999(and so on, this is infinite decimals)%.

OK, picture it this way. What do you add to make it 100? Where is that . infinity 1? It doesn't exist. You can have a 1 tacked onto infinity because infinity goes on forever. It's like a line that keeps going on and on. The 1 would keep moving back trying to find the end of the line but would never find it.
I suppose you want more proof...
OK 100% (or 1) = 3/3 right?
100%/3= 33.3% repeating
33.3% repeating * 3 = 99.9% repeating
Thus 99.9% repeating = 100%
Comes from the most basic proof of .9... = 1. I hated it and didn't want to believe it but it doesn't really make a difference because it's true. I'd argue the same thing that there is that lost .0...1 in there somewhere but it's impossible for it to exist. .3...3 is just a bad way to express 1/3 but you can't express that lost bit. Either way, I'm never going to fire off infinite shots to get that one shot that fails.
(sorry you probably saw the extra comment but I forgot to add in some stuff that would have otherwise made the math incorrect)

My argument against this is like this: If 2 people get the same math problem wrong, it doesn't matter who was closer to the answer, both of them were not on the target.  99.9 repeating still does not equal 100 no matter how close it is.  If you shot a knex gun at someone and miss the target by 2 millimeters, you still missed him, and he did not get out.  If you make a 59 F and you are only 1 point away from a D, it doesn't matter, a 59 F is still a 59 F, not a 60 D.

Here's another one (similar to TD's proof):

10/11=.909090909 repeating
01/11=.090909090 repeating
11/11=.999999999 repeating

That's an interesting one. Really, repeating numbers were just a bad way to say "we don't have a proper way to represent the result when you divide some even numbers by some odd numbers." So in my mind .9 repeating isn't exactly the same number, it's just a representation for 1 showing that it came from the division of numbers that can't be properly represented themselves.

Something like that, I mean, if you can think of 33.33% as 1/3 than it's the same with .99.

A little bit late, I know, but what TD is describing is an established mathematical theory.

*sigh* OK I'm not even going to bother arguing with math. We don't even need to worry about it because the theoretical reliability percentage isn't really required. We just have to worry about the actual. It hasn't failed yet and thus it has been 100% reliable. I'll get back to you when it finally does fail.

Ok good.  I doubt there is a gun that is 100% perfect in reliability, not even the TR was perfectly reliable for me.  

Well it's pretty much universal law that there's always a chance for something to happen. What are the chances I'm going to be abducted by aliens? Very, very small but that still means I don't have a 100% chance of not being abducted by aliens.
The problem is that to be 100% would be that it would have to work perfectly forever. For all we know, a gun could fire a total of 999 shots in its life time but it could have screwed up 1 if it fired just one more. So it would have a 1/1000 chance of screwing up but because it didn't fire off that extra shot, it appeared to be perfect. There is always that chance but we don't know until it happens.

lol, whats the fault of the 0.0000000000000000000000001 lol? btw any pics of your new gun yet???

I have some preview pics on Facebook and the instructable is coming as soon as I get free time.

k, what is the gun???

That's for me to know and for you to wait for.  

And for you to talk about in your own thread.

A bit late but I decided I'd rebuild this because my ideas kept failing but I wanted to have a gun around to shoot. I decided I'm gonna make that video I failed to do the last time I made it. If it wasn't so wet outside I'd do it out there so that I could get an accurate range measurement but oh well. I could add that in later if I wanted to.

Alright I think I'll add the mods into my 3.6 ible later this week. Then I'm done with the series for good. I could probably make an entirely new oodammo pistol and make it as strong built as the MeZak but the whole reason I made the V3s were for their compromised strength and compactness.
I don't know what else to build. I'll probably just have to take a break for awhile.

Awesome sights!

I made a dot sight like that that is even better months ago, I just haven't gotten around to posting it.  Maybe I should.

I like the sliding mag tilter.

Looks good, the sight is awesome

how do we know you didnt do yellow tape with black stripes?

Because it would be much easier to just use the width of peices of tape I had instead of cutting them into tiny strips? I went once completely around with black tape and ran out. It wasn't as smooth as I liked it so I added just a few strips of yellow because I didn't want to waste anymore.

PS. how many mini knex adapters?

Wait so you're of Asian descent?

I hope that was a joke.
I'm actually of Irish, Belgian, Scottish and god knows what other northern European nations descent. I was joking about my own construction of very large text walls.

too much to read, but nice i hope you dont update it even more.
