- This file contains information on making a replica of a German
- WWII mine known as a pepper pot. This mine was not intended to kill the
- enemy but wound him by blowing off his foot. The Germans made these in great
- quantity and put them to good use. The mine was made out of glass and plastic
- with very little metal and was hard to find with a mine detector. If you
- desire to make these mines you could use PVC for the casing or metal if you
- don't care about them being detected. The mine will be presented in two parts
- the mine fuze and the mine body (see accompaning GIF file).
- I do not advocate hurting anybody but if there is a time and circumstances
- for it you will have the knowledge.
-
- Mine Fuze: This fuse is simplicity itself. It uses the reaction between
- sulfuric acid and a potassium chlorate mixture to cause instantaneous deton-
- ation. To begin, obtain some soft glass tubing with an I.D. of 1/8". Fuse
- one end shut with a propane flame. This is done by holding one end of the
- tube higher than the other end and rotating this end in the flame until it is
- sealed. Let the glass cool down. Now using an eyedropper fill the tube about
- 1" with the acid. Heat the glass right above the acid until soft then twist
- off the excess glass tube. Fuse this end of the ampoule so you are sure it
- can't leak acid as this will be fatal. Wrap up the ampoule in tissue paper
- for a day or two to check for acid leaks. Any leaks will eat the paper.
- Get a soft brass or copper tube about 2" long and 1/2" I.D. Find a soft steel
- bolt and drill a 3/16" hole through the center of the bolt. This will be the
- threaded flash tube. If you have to cut the length of the bolt down, put a
- nut onto the bolt first. Cut the bolt then turn the nut off. This will help
- keep the threads clean. File the head of the bolt to fit inside the copper
- tube and solder the bolt into the tube.
- Put 5 gms. of Potassium Chlorate and 2 gms. of Sugar in the least amount of
- hot water to make a paste. This will be enough for two or three fuzes. Coat
- the inside of the copper tube with this paste and let a little small amount
- get into the flash tube. Set the fuze aside for a couple of days to dry.
- Insert the acid ampoule into the fuze and fashion a cover from a piece of
- brass sheet. This cover is then epoxied onto the fuze to seal it. Seal the
- open end of the flash tube with masking tape or similar but don't foul up
- the threads. The fuze is done. You can test it by putting on a pair of heavy
- boots and stepping onto the copper tube and crushing it. It should flare up
- and shoot a flame out of the flash tube.
-
- Mine Body: By now you should have decided whether to use a plastic or metal
- body for the mine. This body should be about 2" in Dia. and 3" high. Seal the
- bottom of the mine and fashion a cover to seal the top. Drill a hole through
- the center of the cover and epoxy a nut that matches the flash tube over the
- hole. If you are using a PVC cover, check that the epoxy holds the nut onto
- the cover. You may have to use a PVC adhesive.
- Make up an explosive consisting of 90% fine ground Potassium Chlorate and 10%
- Paraffin wax. Grind up the chlorate with a wooden stick on a slab of wood to
- avoid all sparks and shock. Melt the wax and pour it on the chlorate. Mix it
- in while it is still hot. Add a little ethyl alcohol to the mix to help the
- wax spread through the chlorate and mix again. While it is still damp from
- the alcohol, load the mine body with about 2 oz. of explosive. Do not press
- the explosive in to firmly as ot may not detonate if packed too dense.
- Push a 3/8" dowel through the center of the explosive to make room for the
- detonator.
- The detonator is made by taking a 3/8" brass tube and sealing one end with
- epoxy. 2 gms. of mercury fulminate is then pressed into the tube in 1/4 gm.
- increments. If you do not know how to make fulminate, look for my file on
- detonators on the HotLine.
- When the mine is to be used, dig a hole in the ground the same height as the
- mine with the fuze installed. Put the detonator into the mine and screw the
- fuze into the mine body. Put the mine into the hole and carefully cover it
- up with dirt. The fuze should just be below the ground about 1/4".
- When someone steps onto the fuze, the flame flashes into the detonator
- setting it off which in turn detonates the chlorate filling.
- If you do not want to use a detonator, use an explosive filling of 75% Pota-
- ssium Chlorate and 25% Sugar. The flame coming through the flash tube will
- cause this filling to explode. The explosion will not be as great as the
- chlorate/wax explosion but it will still cause damage.
