crossme18 Frequent Poster	posted May 17, 2000 12:28 AM What are some devices that could be used to make a time delay bomb. Like the bomb it'll explode 2 hours later. Don't give me any Alarm clock ones hehe. I need something better. Also ways of making a mail bomb. No I ain't going to mail a bomb just wanted to know. I'm reading about Unabomber. Thanks. Randy
Nunchaku Frequent Poster	posted May 17, 2000 02:26 PM a pipebomb could be easily be fitted with a time delay system. i have a plan of it and i'll try to post a photo of it here. BTW, for a device for a delay of 2 hours an electronic alarm clock is the simplest (effective) method
Maddoc Frequent Poster	posted May 17, 2000 04:10 PM Mail Bombers: Walter Leoroy Moody had to be the best, everone who opened one of his packages got killed by flying pipe and hundreds of 2 inch nails. His bombs had had a pipe bomb, fitted inside a cardboard box. The power supply was 2x 9v PP3 batteries. It ustilised a switch that closed the circuit when the box was opened. The pipe bomb was 1 1/2 inch diameter by 6 inches long. It had 2 inch nails rubber banded to the pipe. It was filled with bullseye smokeless pistol powder. The switch was designed much like a clothespin tripwire switch but used cardboard tabs and aluminium foil instead of a clothes pin. It was very well thought out, however, was very simple in design. But every person who opened one of the packages was killed by the pipe bomb and nails. ------------------ Whoa, where my fingers?
crossme18 Frequent Poster	posted May 17, 2000 04:55 PM Closed the circuit to what? I see it everywhere. I am confused. What do I use to make the bomb go off. Lighbulb? Lighbulbs are crappy detonation devices to me. So what do I use? I tried a estes rocket ignitor but doesn't seem to work. Let me know.
Ho ju Moderator	posted May 17, 2000 05:07 PM what i always use to light anything is a wire (with a rubber coating) with many copper stands in it that make up the wire. cut all the strands on one part of the wire except one. expose about an inch of that one lone wire. run a current through it and it will heat red hot. this works fairly well. another method is to hook one or two strands of steel wool to aligator clips and then run a current through the clips/steel wool. this will work too. ------------------ -Knowledge is power, power leads to corruption, corruption is a crime, crime doesn't pay. So if you know to much you will go broke!!! [This message has been edited by Ho ju (edited May 17, 2000).]
Maddoc Frequent Poster	posted May 17, 2000 06:20 PM The ignition method on his bombs was by means of a strand of steel wool. Steel Wool actually works very well as it burns and glows red hot when a current (about 6 volts or over) is passed through it. And estes rocket ignitors are even better. I use them all the time on my cannon (20 inch barrel, .50 cal) and they have never failed once. However I do use a 12v car battery with them.
m3nth Frequent Poster	posted May 17, 2000 07:59 PM dare i post msg 2000 on this forum? oh well someone else probably already has as i type. anyway yes both items mentioned above work... the key is using a battery with high current capability... such as a car or lantern battery. the unabomber used several D cells--in series to get the necessary voltage and D size to have the necessary current. ~m3nth~ ------------------
glock Frequent Poster	posted May 17, 2000 08:09 PM about how many D cells would be required ? ------------------ WARNING - Tresspassers will be shot, Survivers will be shot again.
Ho ju Moderator	posted May 17, 2000 09:04 PM i hate to burst your bubble but the 2000 mark has already been reached many times. but things get deleted/pruned down below 2000 every now and then. so you hit the 2000 mark THIS time. i would say use 2 or 3 d cells. it only takes like 4 AA's to light an estes ignitor using 20 feet of wire. ------------------ -Knowledge is power, power leads to corruption, corruption is a crime, crime doesn't pay.

crossme18 Frequent Poster	posted May 17, 2000 10:35 PM Ok Thanks all. I got a few lantern batteries(6 volt). I got 2 estes rocket ignitors. I put the ignitores inside the rocket motor. Will the motor be good enough to set off gunpowder. Or should I just put the end of the estes rocket ignitor in the gunpowder itself. Let me know. Thanks. Randy
BoB- Frequent Poster	posted May 18, 2000 02:00 AM maddoc, if you put enough current (27-volts works nicely) through steel wool it melts and the ends where it broke grow white-hot 3-9volts works, but it sucks em down real fast ------------------ Look Ma No Hands! (there over by the shed)
crossme18 Frequent Poster	posted May 18, 2000 02:24 AM For the experiment I have I am using 2 lantern batteries with 2 rocket ignitors. The ignitors set off the rocket motor which hopefully sets off the BP. I'll let ya'll know if it works. Its triggered by a good detonation device. Thanks. Randy
BoB- Frequent Poster	posted May 18, 2000 03:22 AM rocket engines are a very cool device, on the opposite side of the nozzle theres is a chunk of fire clay seperating the BP and the parachute so it doesnt melt, scrape away this fire clay with a screwdriver or thick knife (on the parachute charge side not the nozzle) until you hit the bp continue to scrape away the fire clay until only BP remains (not necassary but helpful) then either fill it with a powder for use as a time delay or put in some powder and insert a fuse I use to make "super bottle rockets" with this method, it works ------------------ Look Ma No Hands!

Maddoc Frequent Poster	posted May 18, 2000 01:37 PM I hope I'm mis-understanding your message. The rocket ignitor on its own will set off gunpowder. You dont need a rocket engine to do it. Have you ever even used a rocket ignitor, in case you haven't (which it seems like)it glows red hot and will set of almost any heat sensitive explosive. ------------------ Whoa, where my fingers?
BoB- Frequent Poster	posted May 18, 2000 05:41 PM yes, I was talking about rocket engines for use a delay not rocket ignitors which are also cool, sometimes I cant beleive they sell this stuff ------------------ Look Ma No Hands! (there over by the shed)
BoB- Frequent Poster	posted May 18, 2000 05:46 PM or get a sprinkler timing device they sell these at my hardware store the plus is they run off 12-volts which means 2 lanterns ------------------ Look Ma No Hands! (there over by the shed)
