PIPE HAND GRENADE |
|
| Hand grenades can be made from a piece of iron pipe. The filler can be plastic or granular military explosive, or propellant from shotgun or small arms ammunition. | |
| MATERIALS REQUIRED: | |
| Iron pipe, threaded ends, 1 1/2" to 3" diam., 3" to 8" long. | |
| Two (2) iron pipe caps. | |
| Explosive or propellant | |
| Non-Electric blasting cap. (Commercial or military) | |
| Fuse cord | |
| Hand drill | |
| Pliers | |
|
|
|
| PROCEDURE: | |
|
1. Place blasting cap on one end of fuse cord and crimp with pliers. |
|
|
NOTE: To find out how long the fuse cord should be, check the time it takes a known length to burn. If 12 inches burns in 30 seconds, a 6-inch cord will ignite the grenade in 15 seconds. |
|
|
2. Screw pipe cap to one end of pipe. Place fuse cord with
blasting cap into the opposite end so the\at the blasting cap is near the
center of the pipe. |
|
|
NOTE: If plastic explosive is to be used, fill pipe before inserting blasting cap. Push a round stick into the center of the explosive to make a hole and then insert the blasting cap. |
|
|
3. Pour explosive or propellant into pipe a little bit at
a time. Tap the base of the pipe frequently to settle filler. |
|
|
4. Drill a hole in the center of the unassembled pipe cap large enough for the fuse cord to pass through. |
|
|
5. Wipe pipe threads to remove any filler material. Slide the drilled pipe cap over the fuse and screw handtight onto the pipe. |
