would this gun work. would I need a stronger bolt. or stronger rubber bands(like uh,, those tie down things that you use for trucks). I want to shoot .22's out of it. oh yeah, does anybody here know where I can find a .22(1/4") caliber pipe(the thick iron kind) I can get Al. tube and copper but cant find real pipe anywhere in a size that small. oh well I guess I will have to shoot 12 guage out of it {sigh}. oh one thing I forgot to add to the picture is I think an endcap would work better than tape. ------------------ |

That drawing as it stands will not work. This is because the firing / hammer nail is not supported to move in a linear direction towards the bullets primer when released.. maybe if you had a washer inside the pipe for the pointy end of the firing nail to sit on though ------------------ |

Just remember that .22's are rimfire, that is if you end up using .22's. |

I was going to say the same thing as predator, when you pull the bolt/nail back and release it, it will miss the hole. The rubber bands will pull it downward and it will not make contact with the primer. Dont use rubber bands, use some springs. I made a gun similar to yours and it works. Expect mine is bolt action, Ill try to take some pictures of it. Oh and you cannot use 1/8" pipe for the .22 barrel, it isnt strong enough. For my barrel i got a 3/4" steel rod and drilled out the barrel myself. It took me 4 hours and the damn hole was crooked but it works. A better idea would be to goto a gun store and purchase a replacement barrel. For my bolt, not the barrel, I use 1/8" inch pipe, since it is hollow my firing pin can live inside the bolt. I use springs for my firing pin. I made it so that as you bring the bolt forward and lock it, this action also cocks the gun so once you close the bolt you can just pull the triger, with no extra shit to do. Since your barrel wont fit the .22 exactly, its a good idea to put an 0-ring on the .22 bullet right in front of the rim. Anyways, Ill get my pictrures sometime in the future so you all can see it. ------------------ |

yeah i would think that buying a new barrel for your gun would be the best/safest way to go about this. ------------------ |

A note there on Feticidal Fantasies post. buying a gun barrel in some countries require certain criteria to be met. A.) you must hold a FAC (Firearms aquisition certificate) If however, you buy a cheapo air rifle from the store, that requires no license since it's power level is below 12ft/lbs. (but your not interested in the gun, your interested in the barrel and make sure you get one with the desired .22 barrel. |

your diagram looks too flimsy It wont be without its problems, first the barrel would have to remain freefloating to allow reloading - unscrew barrel and insert cartridge - screw barrel back - pull plunger back, and itll be ready to fire..

nice. turn this into 9mm. make some sort of clip(magazine) or use like a tommy gun clip or something and you could have a full auto gun. SWWEEEEEEEEEEEEEEEEEEETTTTTTTTTTTT. ------------------ |

eh.... 10000psi? Where did you get that figure from? Shotgun shells regularly run at 65000psi+ up to and surpassing 78000psi... ------------------ |

I think youll find that its rifle cartridges that run up to 78000psi... shotshells are considerably less, although i no longer can find a source of my info. can you provide a source to contest it? 9mm's have a rimless case, so the above design wont work... .357mag has a rim. |

Why not attach the actual pin to the hammer thats pulled back by the spring. This will make it quite a bit more reliable. Also how in hell where u planning on making sure the little pin was going to stay in place? |

the reason i put the firing pin into the end cap was , because if it was in the cylinder everything would have to be exact - the cylinder would have to be a perfect fit for the pipe and the pin would have to be perfectly centred, youd have to have the parts custom made. Fitting the pin into the endcap wouldnt be too hard, maybe have a spring around the pin fixed to the endcap and onto a small plate on end of pin, that should work. |
