Introduction: TBAP V3. Concept Pistol (Thunder Bolt Assault Pistol)

Picture of TBAP V3. Concept Pistol (Thunder Bolt Assault Pistol)

Hey guys and girls,
I know I just posted version two of this gun, but I had some new concepts for an Oodammo pistol and I wanted to try them out.  I wanted to try to make a no-friction ram lock.  If successful, this would put no friction on the ram when it is being shot, but still successfully keep the pin in the gun when being pulled back. This was achieved by using mini knex. Yes, mini knex. They finally have played a good role in knex guns!  The small red piece that connects regular knex to micro knex is used.  The small end rides in the grove on the ram and catches the ridge on the ram. It is placed in a way so the lock adds no pressure.

The other new thing on this gun is the mag. I'm not sure if anyone will like it because we tend to be set in our ways. But the mag slides down, giving you room to fill the mag. It also uses a rod as a mag pusher and typical bullet lock to hold the mag pusher. Now you can modify it to use removable mags, but they really aren't that practical in war. One of the advantages of this mag is that it wont fire two bullets at once. The reason this typically happens is that the rod the bullets ride on is too short. That's a hard problem to fix seeing that knex only have so many connection points.  But if the mag slides up and down, you can make the gap between the rod and the barrel smaller.

These are the two new concepts.  I want to know what everybody thinks. It only takes a few seconds to comment.

Step 1: Step 1

Picture 3: Add them on.  (image note)

Step 2: Step 2

Picture 2: add
Picture 3: add
Picture 4: add
Picture 5: add
Picture 6&7: add to the rest or the gun

Step 3: Step 3

Step 4: Step 4

Picture 1: Add this panel.
Picture 2: Add the two blue spacers.
Picture 3&4: Remember this guy? Add him on.

Step 5: Step 5

Picture of Step 5

Picture 1: Build these two panels
Picture 2: Build this
Picture 3&4: Put the two together.
Picture 5: Make this
Picture 6: Make this
Picture 7&8&9: this is the mag. I didn't want to take it apart. You can figure it out.
Picture 10: slide it onto the rods
Picture 11: get the spacers
Picture 12: add them to the rods
Picture 13: connect it to the rest of the mag.
Picture 14: add the mag to the rest of the gun.

Step 6: Bands and Loading

Picture of Bands and Loading

Picture 1: Make the ram and get these.
Picture 2: add wheels
Picture 3: insert ram
Picture 4&5: add bands

To load pull the mag pusher down until it locks. Slide the mag down and load it with oodammo.  Push it back up and release the mag pusher. 

To fire pull the ram back until the trigger blocks it and pull the trigger.

I hope you like it. Don't forget to subscribe!

Can I make this gun without y-connectors and ball sockets?

skyfaller (author)2011-09-02

How does the mag pusher lock? i dont get it o-o .

Whenever i pull it down, it just shoots straight back up, and i already tried pulling it all the way through if thats what i was supposed to do but it still went back.

Use a small weak band.

mulletman6 (author)2011-08-03

Trigger and mag didn't work properly for me :/

lphillips094 (author)2011-05-21

very useful.
but im not sure i would build it, last time i ever mad an oddammo pistol it was so bad that i took it apart within minutes and never built one again

Sorry that happened. You probably just picked a bad one to build. Most oodammo guns work well. I say you should give it another chance.

i will try again, the one i built was the jackal by dj radio

Yeah.. well there's your problem. :p

Seleziona (author)lphillips0942011-05-24

That one really doesn't work that well, you really should try making a different one.

lphillips094 (author)Seleziona2011-05-26

i will

Just to clarify, this uses ONLY the red mini knex bit?

Cheezpaper (author)Cheezpaper2011-06-08

Oh and does this work better than the V2? I'm too lazy to build both, so a quick reply would be appreciated.

Yes this only uses the red mini part. It really depends on what you want. This gun is more reliable, but the V2 is more of a classic.

Sadly, I have no blue-to-black hinge pieces. :(

Could these be replaced successfully with some hunk of single connector contraption?

I don't remember where all they were used on this gun. I only see the one, but you can try to use a green connector.

I like the idea of the sliding mag and using micro knex. You deserve 5 stars...

TheDunkis (author)2011-05-25

Interesting. It's possible to achieve a near frictionless pin lock without mini k'nex, though. Still, a nice demonstration. The mag is going to be a love it or hate it kind of thing I can tell. Again, it's a great demonstration but not the most practical. I dislike the small mag size it allots you compared to the size it takes up. Don't know if you already considered it, but one concept I was working with was making a sliding magazine. Perhaps you can perfect it. It would be more efficient to make the magazine slide horizontally rather than vertically.

Yeah, I'm sure there is another way, but this is just a concept. I personally like this lock the best. Like you said with the mag, some will love it and some wont. All of this gun is just a concept. I wanted to show my ideas.

Hmmm, interesting. I'm not sure how secure a mag sliding that way would be though. What about twisting to one side? And even as much as I hate them, it might be able to take better removable mags.

I was figuring it wouldn't hurt to be able to accept removable mags if you could also make it so you can load them in the gun via a sliding or tilting mag as well. It'd need to be something that you could extend the size of to give it any real advantage over clips.

And the advantage I was thinking with a sliding mag is that it must be locked vertically for it to slide, right? So that should improve reliability greatly in that the magazine won't have any room to open up.

cool! better looking than the second

Nice, especially the mag =D

Football viking boy (author)2011-05-23

what's the red thing in pic 4 and where do you get it

That a piece of mini knex. You can get in most new sets.

sukinmaru (author)2011-05-21

How mini ARE these pieces, I didn't see them 0_o
Should I get a microscope? Where are they in the pictures? Sorry, I'm blind.

It's one piece. Step 3 picture 4.

About how long is the mini-knex stick? The length of a green rod or a white one?

Its in between both of those.

Could I have a measurement then?

7/8th inch. About1 inch.

Thank you very much! Might just grind down a white rod to make this.

Ah, ty

Nice =)

Senior Waffleman (author)2011-05-21

Nice, but the mag seems a little bulky in my opinion, but oh well, still 4.5* :D

The mag is a concept. A new way of doing things.

Ohhh, ok :P

tytiger33 (author)2011-05-21

Can you post a mod to get rid of the micro knex?

I probably could, but I don't want to. It works great, and using micro knex is one of the innovative parts.

Ok well I like version 2 better any way. And are you going to post a gun with Eliminator Assault Pistol's mag but on the bottom?

MegaMetal8 (author)2011-05-22

Very good.

The Nomlack (author)2011-05-21

Damn i got no mini knex...

beanieostrich (author)2011-05-21

This is just flat-out epic. One of the few guns that would get a 5* rating.

Thanks man.
