Hand Grenades can be made from a piece of iron pipe. The filler can be of plastic or granular military explosive,
improvised explosive, or propellant from shotgun or small arms ammunition.

Material Required:
1-Iron Pipe, threaded ends, 1-«" to 3" diameter, 3" to 8" long.
2-Two (2) iron pipe caps
3-Explosive or propellant
4-Nonelectric blasting cap (Commercial or military)
5-Fuse cord
6-Hand Drill
7-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 the pipe. Place fuse cord with blasting cap into the opposite end so that 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 hand tight onto the pipe.

How to make gunpowder for the PB
Saltpeter (AKA Stump remover, niter, potassium nitrate)
charcoal
sulfur
Grind all the ingredients to a fine powder (NOTE: do this all separate)
and measure all the ingredients (74.8% saltpeter, 13.3 charcoal, 11.9% sulfur).
Than do all the ingredients all in the mortar and moisten it a little bit.
(NOTE: when all the ingredients are added and the black powder AKA gunpowder is made, do not put any sparks or fire near it as it may ignite)
