TBAP V3. Concept Pistol (Thunder Bolt Assault Pistol)

About: Im Killer~SafeCracker, I started using Instructables in 2009. I mainly post in the Knex world, but I venture out sometimes. Check out all my instructables, you wont be disappointed! I live for music and I p...

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 1: Build these panels
Picture 2: Make these guys
Picture 3: Add them on.  (image note)
Picture 4: Build these panels (image note)
Picture 5: Add panel
Picture 6: Make this
Picture 7: Slide over the rods

Step 2: Step 2

Handle Time!

Picture 1: Make all these parts.
Picture 2: add
Picture 3: add
Picture 4: add
Picture 5: add
Picture 6&7: add to the rest or the gun
Picture 8: slide the gray connector over the rod.

Step 3: Step 3

Picture 1: build these
Picture 2: Add
Picture 3: Add
Picture 4: Make this
Picture 5&6: add to the body
Picture 7&8: add to the body

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 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 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!

    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.

    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.

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

    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.
