that would make for terrible compression. unless you had like christmas bulbs coated in cement or something. go to the casings! sticky and look at the casings.

christmas bulbs? you cant even put a little bity of gun powder into one of them. no pressure build up it shoots out fire. besides i couldnt fit what i have right now into a christmas bulb if i was retarded enough to try it. and ninja i looked at the sticky theres nothing i could find to work short of a large plastic casing. and i would only do that if i was really desperate

The problem with this? Even "decomissioned" grenade casings are required under federal law to have the bottom shaved off, thereby removing the pressure buildup which causes the actual explosion. If it is not shaved, it is considered by the BATF to be a "destructive device", and you can be imprisoned. However, if someone were so inclined, it would be easy as hell to break out a mig welder and correct the situation.

I'm guessing if you have access to a mig welder, however, you probably also have access to other metalworking tools. Use a 2" pipe, about 3" long. Thread the ends, and cap them. Drill a hole and tap it for use with a very small piece of threaded fuel line, the smaller diameter the better. Dip the end in melted wax, just enough to cover the end, fill with powder, and use cotton wadding and cannon fuse to light it.

When the cannonfuse burns down to the actual fuse tube, you will notice a distinctive flash when the powder starts to burn. You had better have thrown it by that point, because you won't have much longer before it blows up, chunking shards of shrapnel everywhere...

the thing is that with some high explosives like C4, compression isnt needed. the metal casing is just there for shrapnel and mass so that you can throw it better. with a low order explosive i doubt he would be able to break the grenade even if it was compressed. i obviously could be wrong for i have not tried it, but i think that it wouldnt matter if the bottom had a gaping hole in it. as long as it was placed (for i assume he wouldnt find a timed det that he could put into it...actually i doubt he could get c4) with the hole on the bottom the shrapnel would still go flying. and even if it wasnt on the part with the hole, it would still send shrapnel. just not as evenly.

although i am not sure of the filler used in grenades, C4 was just an example of something he could put in it to make it explode without the bottom.

and squirrel, by Christmas bulbs he means those big round shiny painted glass (or usually shitty plastic) bulbs that people hang from their xmas tree (usually red green or gold). not the lightbulb. and if he did mean the lightbulb i dont know what he was smoking. i have heard a xmas lightbulb can be used for an electrical ignition source, however i do not know for sure, but it certainly wouldnt be a good bomb.

it doesnt matter about the christmas bulbs i wouldnt be able to fit the pin, percussion, and primary in there unless its a really fucked up lookin christmas bulb.

Xmas lightbulbs make excellent electrical ignitors. Industry favourites, they are.

But really, it's not hard. You want a thick casing that'll make shrapnel? Loathe as I am to say it, you just need some metal pipe.

ill look into christmas bulbs as electrical ignitors, but i think ive got everything i need for the grenade. hope everything turns out alright. thanks ghost

would the filliment need to be in a vacuum to become red hot? or could i just dremel it in half (being careful not to break the filliment), then fill it with a low ignition temperature powder of somesort and glue the top back on?

Yeah, that's work fine. personally I just crack the globe with vicegrips by carefully wheeling up the jaw pressure, and then immerse the filament in my comp.

thanks, and yeah, i read the your post about it (maybe it was in fuses?), i just wasnt sure if the filiment needed to be in a vacuum.

how much voltage/amperage would it need minimum to ignite if it was with a nitrocellulose/rocket engine powder mix firstfire approximately? would i be able to use wattage to convert into degrees and then look up the ignition point of the powder? or does wattage not have a direct correlation with degrees? because i dont really know much about power, only that a resistor with a larger physical size will dissapate more heat, so is rated for more watts
