You could wrap that thing up in a tennis ball and get a more "camouflaged" look.

That is hilarious. We have a Destructive Devices forum but any talk about the DD themselves except "I have one" is prohibited.

Quoted: Since you asked, here's the first trial of casting the body. I'm getting new molds and going to try it again this weekend for a more uniform frag matrix before wrapping the thing in Kydex. http://i1285.photobucket.com/albums/a595/Wingnut116ACW/IMG_20140203_095333_zpsf042c2e8.jpg View Quote Edit: Statement redacted due to this apparently not being a discussion forum. |

One thing I would recommend is, using a plastic that will shatter and release the balls, rather than rip open at the weakest point and hold the matrix intact. If the plastic is soft, you will not get the grenade effect you are looking for. I also recommend searching a few explosives forums for RDX as a filler, instead of some sort of flash. You will need, of course, your explosives license, but if you are making a real grenade, a real DD, you might want to go there... Otherwise, you should just glue some BBs to an M80 and call it a day. Good luck, GROG

Good luck, GROG View Quote I whole-heartedly agree with GROG - except for the bold part. That is technically a 'Destructive Device' or BATFE words for an illegal BOMB. A low explosive, isn't REALLY an explosive, it is just a propellant that the initiation wave never breaks the speed of sound in the energetic material. An example is a gunshot. The sound wave is broken by the propellant igniting & being MECHANICALLY contained but there never is a DETONATION in the weapon. RDX is ridiculously easy to make, although expensive. Its about $500 for a pound if you make your own precursors. Its WAY more expensive if you buy your precursers! Next, fume control and RINSING the final product are the main issues - then the next issue would be igniting it. You would need to then build your own blasting caps. There have been many energetic/explosive chemists that have cut short their career due to blasting cap mishandling. The most recent one I can recall is the incident out at Fort Carson in 2012 in which a well known energetic materials chemist was injured during training with an improvised blasting cap. Best of luck! Will |

Its pushing the bounds, where others want to say blanket "NO" & "CAN'T DO THAT" - this is a "YES I CAN" Which is more akin to AMERICAN instead of the AmeriCAN'T folks that are out there.

I actually did some filler tests today that went so well, I'm marking the filler question off my to-do list. A pound of the binary filler I used was able to blow a sandbag in half, and I lost the metal stake the charge was attached to. When I can finally finish up this project, I'm going to go for land mines only because I CAN. |

If I may ask, do you have any state or local regulations to contend with when handling/storing explosives?
If grenades were commercially available I would totally throw down a thousand bucks or so on stamps to buy a half a dozen grenades. The grenades themselves would probably be pretty inexpensive. Congrats on your form 1. |

Sorry. Ed Sr says no or everyone would want help doing a project. I think we could raise money for you only if you were the blast radius test subject, and we don't want that. We'll have to try elsewhere.

The blue M33 trainers don't have the ball bearings in them. They use whatever the cheapest scrap metal is that the manufacturer can get ahold of.

I have a very simple blast land mine design that I just came up with that uses a waterproof round electrical gang box, a cat whisker limit switch, a tamper switch, and some watch batteries. By my bar napkin calculations, it can hold around a pound of filler.
I need to pull about a half dozen tax stamps for the projects I have in mind. |

View Quote But the ball bearing matrix is the easiest part to build. For a directional, command-detonated mine, I'm really eyeballing round electrical enclosures. They're already waterproof, they have threaded attachment points that can be adapted to become cap wells, they are very very cheap and available practically everywhere. Also, since I'm keeping an eye toward modularity and adaptability, they can also be stacked or adapted from antipersonnel frag matrix to EFP shaped charge with the swapping of a couple screws. Just a thought though. That project should go quickly, but I need to put in for a stamp first. |

I have several thoughts on usage for you "mini-mines", but I'll keep them to myself.
I'm sure if you reread the improvised weapons section of the soldiers handbook you got in basic (from the 80s) you'll find some ideas. I'm not sure they cover this in these more enlightened, PC times. |

CMS Egg Zachary. They are not "regulated" ...at all. One of my instructors at IBOLC had them stacked like 18" inches high on the antenna of his gov't S-10. He just picked them up all the time in case he couldn't find one he needed himself one day. Hell, I have a few spares hanging off my rig right now. Plenty of us have also made it home with the odd smoke or star cluster over the years no doubt. I will say I've never tried to erhm, "misplace" an actual grenade though. |

For my own fabrication, I'm tending toward a modified POM-Z2 Yugo stake mine and a modular mini claymore of my own design. |

The PMA-2 is basically a skoal can with a multi-prong pressure system that goes into a crushed glass & Armstrong initiator.
Not much to model. The M14 actually has some good cutaways on the Internetz. The Canadian M25 or C2A1/C3A1 "Elsie" or whatever you want to call it is a little more intensive due to its spike shape. |

So is it completed yet? Also a you plan on pulling the pin OP?
