Look at the investment cast golf club heads. |

If you have a lathe and a milling machine you can make pretty much everything but the barrel, assuming you are making a rifled bore. I made a smooth bore .22 that worked from a car antenna and a bunch of fiberglass wrapping. It was chucked up in a cap gun with most of the hammer filed away. The problem was the brass came out the back almost as fast as the bullet went out the front. My dad owned a major machine shop. We made a few breech loading cannons, mostly Jetex fuses through the drilled out bolt. Would put a 5/16 ball bearing pretty much through a 4x4. |

When you're a Jet you're a Jet all the way, from your first cigarette to your last dying day ... ;-) All I can come up with at 0045 Sort of "Souf eese Story". |

Nowadays you also have to make a video of it to truly qualify as a stupid kid trick. It's fairly easy to improvise a crude milling machine if you have some woodworking tools, small grinding wheels, cross slide vice, etc. I have no idea how to make a rifled barrel but it's not really necessary for short range. There's probably something on YouTube however. The traditional machine (18th century) was just a scraper and a jig to keep the twist consistent but it was usually just 2 lands and 2 grooves. If I was doing it I would try to scavenge a barrel or just buy a replacement barrel from a gun parts place. Like I said earlier, most of the parts in a gun are available without being serialized and tracked. That guy in Idaho was only casting and polishing the AR receivers and buying everything else online. |

The problem was the brass came out the back almost as fast as the bullet went out the front. My dad owned a major machine shop. We made a few breech loading cannons, mostly Jetex fuses through the drilled out bolt. Would put a 5/16 ball bearing pretty much through a 4x4. I still have my cannon. It was a souvenirs deal with a cast iron base and a solid brass barrel. I drilled it out to a clean 1/4", put a sling shot ball in it with a little bit of paper towel wadding and use the material from kitchen match heads for powder. You just broke the white tip of a kitchen match off in the touch hole (before you load it) and touched it off like the old style cannons with one of those long fire place matches. I am not sure about a 2x4 but it would go through 1" (3/4) white pine. I saw it in the garage the other day in a drawer with some of my other dangerous old stuff. Did anyone else have a Henleys formulas book? I had the old red one until it fell apart and I found a reprint with a black cover some time in the early 70s. Screw Tropic of Cancer, That was something that should have been banned. I am surprised I am still alive, Berges blasting powder was neat tho. (potassium chlorate, potassium chromate, sugar and a pinch of wax). Potassium chromate and sulfur (AKA fulminating powder) is what goes in "torpedoes". Those things you thrown and they explode. Just use a few chunks of fish tank gravel, a pinch of the powder and wrap it in paper mache' When it dries out, you got ya sumpin. The potassium chlorate is the only one that is hard to by but our chemistry teacher had an account at Fischer Chemical and I used to help him out, picking up a few things for him. Everything was cash in those days so I just added a bottle to the order ;-) I still may have a little in that drawer. I think there is some zinc powder in there too. Great rocket fuel when mixed with sulfur but potassium nitrate and sugar works too. You have to melt that and it is a little scary the first time you do it ..Rocket motors are co2 cylinders drilled out to 1/4" and you put them in a Bering cigar tube. Shoot them out of a 1" pipe and say goodbye. I don't think we ever found one. I never had much luck with the gun cotton and I was smart enough not to try nitroglycerine |

Zink and sulfur fuel. We used aluminum tubing, and had a pair of pliers the that had a necked down area that made perfect nozzle. Made one about a foot long and 1" diameter. Do not know how far it would have traveled, except it tilted on launch and hit the gutter on a 2 story house a 1/2 block away. Probably better for us to hit a house than a car a block or so away. |

Dad's buddy was the range master for a military range the NG and FBI used, so dad got lots of very cheap ammo. We would disassemble.06 rounds. |
