The Ditto Bow

Okay so, it's been a while since I've last been on ibles, like a couple of weeks. Anyway, I finally managed to get around to posting one of my k'nex guns, so I decided to post the original version of a gun that I've been working on for quite a while. I know I said I would post on Christmas but that didn't work out too well. First off, I have a computer that's older than dust, and the internet speed is really,really slow because I had to pull all of the pictures that I took off of my camera and dump them on my computer,and on top of that I had to resize 60+ pictures.And make an ible for this gun. The point is, I put a hell of a lot of effort into this gun, so it would be nice if it got a good rating and a lot of views.This is the original, and it's not very good, but I posted it anyway. Onto pros,cons, and instructions:

Pros:
-fair power. It will leave good size dents in cardboard boxes, depending on the bands.
-fair range. I would say it would shoot 40-50 ft. if you're lucky.
-trigger blocks behind the handle and operates on zero bands.
-8 shot turret.
-ratchet holds all of the guns bands to keep pressure off the pin.
-has an ammo holder and a rear sight.
-some parts of the gun are removable and interchangeable.

cons:
-piece consuming. it especially uses a lot of bronze connectors, like over a hundred of them.
-a bit bulky. I'm going to do some mods to it to cut out some of the bulk after I post the v2.
-handle is a little flimsy in one area. I thought of a way to fix this but I'm not sure if it will work.
-power of this gun is limited because I haven't been able to make a strong enough pin that wont break no matter how many bands you load onto the ratchet.

Awesome job, just to let you know this is the sorta thing that I would usually build, but I'm starting (I think) a collaboration soon.

Wait, what concept of mine is in here? Looks well done in any case.
SYMEN (author)  Oblivitus1 year ago
Your removable and interchangeable parts concept. And thanks.
That looks pretty neat. It looks like it performs very well. Good job.
SYMEN (author)  Blue Mullet1 year ago
Thanks but, it's not very good. It DOES work, just not the way I wanted it to.
Took forever to get all the way down here! Lol, I like it alot. Nice job!

lol, that's because I put all of the pictures on one step. I test fired the v2 this morning, and a few hours later I heard on the news that astronauts started finding k'nex floating in outer space! lol, I'm just joking, I haven't test fired it yet because I'm still working on the trigger. I'm trying to do a setup where the trigger blocks behind the ratchet instead of under it,like you see in this one. That will be a little harder to do, but I think I can get it done. Sophistication is my type of field.
Hey man. Nice turnout. I have never been a big fan of K'NEX crossbows, but this is pretty nice all the same. Like you said, it is rather piece consuming, but they may all be necessary. I like the size, and I think it looks quite proficient. Let me get this strait. There is a pin, and it is pulled back manually. Then you take the rubber band and pull it back so that it locks on the White/black connecter. When you pull the trigger, the rubber band flies forward taking the pin with it, and thus hitting the ammo. Correct? Lets hope you get SOME recognition. :-)

Happy to see your back.
That's correct. The ratchet(black snowflake piece) holds all of the gun's power behind it, in the best case scenario that would be the number of elastic bands you put on the gun. Because of this, the firing pin is allowed to to slide back and forth inside the guns barrel freely without any external pressure acting upon it. This not only makes any pin gun that uses this mech incredibly powerful, but also very destructive, and could easily damage things if it's powerful enough.I can only imagine the magnitude of power coming out of one of these if it fired one of killerk's sniper rounds. I'm not the only person that made something similar to this. Fred the penguin built the same thing, but he called it The Logic Bow. This one isn't very powerful, more like a fun gun to play around with instead of a raw power gun. The second version I am working on is no joke though. It's not a toy.
Did you ever see my crossbow?
SYMEN (author)  BlackShadow121 year ago
Um, no. But I guess I can go look at it if you want.
You don't have to man.
SYMEN (author)  BlackShadow121 year ago
O...kay? >_>

SYMEN (author)  BlackShadow121 year ago
Oh,thanks I guess. I didn't see it under your ibles. It was probably there, I guess my eyes just went over it and I didn't notice it was there. I'm such a blonde.
Thats ok, so what do you think of it?
SYMEN (author)  BlackShadow121 year ago
Go look on the ible.:p
Ah, I see. Thanks.
Glad I could help. ;)
This is pretty cool man
SYMEN (author)  BlackShadow121 year ago
Thanks!
You're welcome
I skipped a bit through the ible. From what I see, this is great! I realy like how you made the trigger mech to operate without rubber bands.
But I have a question:
Are all the broken blue rods necessary?
SYMEN (author)  dr. richtofen1 year ago
Yes, they are necessary because at the end when you assemble the gun you have to attach those 2 blocks of knex on both sides of the barrel and if the barrel uses normal blue rods then the ends that are sticking out will get in the way of the knex blocks you're trying to attach, not to mention you'd have internal barrel failure if the broken blues aren't there, there's just no way to get around the broken pieces sorry.
Ok. I'll see if I can find some broken grey rods or so, that I can cut into several pieces
SYMEN (author)  dr. richtofen1 year ago
Sounds awesome. I hope it works out for you. I'm working on a second version that uses a rail pin system and is relatively short in length so that it's more piece efficient so that those knexers that don't have a lot of pieces and can't afford to buy more can build it. But if you're a knexer say, someone like killerk who has thousands of pieces wanted more power out of the gun, you can easily increase the length of the gun to make it more powerful, but I wouldn't go past a length of 15 connector units. If you or anyone else builds it and posts a picture I'll add it to the intro.
Yeah. I'll look at the rods in the weekend or mid next week, as I'm an exam week now.
SYMEN (author)  dr. richtofen1 year ago
Sounds good. It's getting late, I should go.
Looks great!
SYMEN (author)  sandroknexmaster1 year ago
Thanks!
Great gun, a bit overkill on the parts but great none-the-less!
I haven't built any K'nex for about a year now (I still have an old Racker Rifle built up) I need to crack out the stuff again next month and have a good go at building my ideas from the past year. Good stuff!
SYMEN (author)  TheFoofinator1 year ago
Thanks! Yeah, I just couldn't find a way to make this gun more piece efficient, that's why it uses so many pieces. I'm working on a second version that could prove to be sufficient, more so than this gun, this is the older version that I posted just to give you guys something to mess around with until I post the second version. I'm not going to go by dates, I'm just going to post it when I can. Try to keep your eyes peeled for it.
SYMEN (author) 1 year ago
Hold on guys, I'm not done with this yet, Apparently I still have to edit the ible even after it's posted. If you're smart enough to build the gun right for the first time,fine. If not, wait until I get done adding annotations please. :)
