-- Posted by Duke1901 on 3:48 am on April 6, 2002 I’m thinking about building a shoulder fired rocket like a bazooka or a RPG. I need help on the impact detonator for the rocket. I have drawn up a rough diagram, any one have any suggestions on how I can improve it?

I have never made one but have played the idea out in my head. so test away and report back what worked and did not work So many great Idea have gotten sweep off the garage floor. So many Kewl Bombers have been scrapped off the walls. or Mix Potassium Chlorate with Sulphur and Dark German Aluminum In a tube with a sealed end and a plunger sticking out so when the warhead strikes the target it forces the plunger down and compress the Mix causing it to explode............

Hope that bit of advice helped. Dont fire from the shoulder until your positive its safe.oh yeah make sure you have a safety pin blocking the firing pin at all times when your not about to fire. -- Posted by thejoker41 on 9:58 am on April 11, 2002 The IRA makes mortars that when flying through the air arms themselfs. A fan on top of a bolt that screws in while flying touches down on a .22 round that is used to set of the main chage when it hits the ground. Its just an idea but sounds pritty solid to me. -- Posted by JC12gage on 10:41 am on April 11, 2002 Yes an arming device is almost nessasary or it is to risky to shoot when you are close.  A 22lr shell right at the tip would be safer I would think.  you would have to have a 7/32" hole in some steel and the rim of the cartrige must have no more that 1/3 of its surface area in contact divided up into 4-5 areas for reliable detonation.  Also you could have an alternate or dual igniton form the engine like a fuze in the back so when it is done burning it lights the fuse and if the impact detonator fails It is shure to go off this way.  but It may explode prematuraly on distant targets.     http://www.bombshock.com
