ROCKET STOVE

Why? Rocket Stoves are:!e" E##$c$e%t: Because they direct all the heat energy (from the flames)upward, most of the heat actually goes into heating the food, rather thanbeing radiated outward (like most campfires).&ot: Rocket Stoves have 'ee% (eas!re) at *+,,- (649 ). !hat iseasily hot enough to melt some metals (lead, bismuth, tin, indium, antimony,and a few others "it#s not $uite hot enough to melt %luminum at &'' *). +tis also hot enough to ignite magnesium.

Sa#e: +f you should abandon your ocket -toe, or leae it unattended, itwill go out within a minute or two.

STE0 +:

*1 ut a 4;inch hole in the side of one of the 3& cans, with tin snips, about'.F cm from the bottom of the can. Go this oer some newspapers, so you

don#t accidentally drop sharp pieces of metal onto your carpet (you don#t wantto cut your foot later, rightH)

+1 +f you cut the hole to the e1act si5e, you will be able to barely fit theelbow;piece of 4;inch stoepipe through the hole (from the inside of the can).Be sure the #corrugated# part of the elbow remains inside the can, pointedupwards.

21 Iith a can opener, cut the top and bottom off the other 3& can, so thatyou can see completely through it.

*1 Jsing the AB Ield, glue the two 3& cans together, making sure that thelid;less one is on the top. :eae this to dry. +t takes '4 hours for AB Ield to

set completely.

!o reinforce this, you can later bolt the two cans together if you want.

+1 ut off a 6; to 6 &K';inch section of the straight stoe pipe (from thesmooth end). it it to the top of the elbow piece of stoe pipe in the ocket-toe.

21 ill the interior of the ocket -toe (inside the stoe, but @=! inside thestoe pipe. !his will be insulation that will keep most of the heat of theflame from radiating outward) with the ermiculite (or ashes or pumice). illit up to about ';'.F cm from the top of the stoe pipe. Dack the ermiculitedown tight.

STE0 :

*1 @ow you can cut strips of metal off the tops of tin cans to create the#spacers# (pot rack) that you need to keep your cooking pot far enough fromthe top of the stoe pipe so that it won#t smother the flame (E;F cm wideshould be sufficient).

Jsing an awl, poke training holes in the 3& can, and in the metal strips,where you want to insert the machine screws, where you need them to be.

!hen you insert the screws and tighten them.

+1 ut off a 6;inch section of the straight stoe pipe (from the corrugatedend). +nsert the corrugated end of this stoepipe into the elbow end thatprotrudes from the side of the ocket -toe.

21 ut another piece of metal from another tin can. +t needs to be 4;incheswide (& cm)(e1cept the ery top inch) and about F or 6 inches long (&E;&6cm). 7ake sure the ery top of this piece of metal forms a slight #t;shape#,with the top being about 4 inches wide. lip the corners off to get rid ofthe points, and file all the edges with the file to minimi5e the danger ofcutting yourself. Th$s $s the tray >here yo! >$"" "ay the st$cks that yo!>$"" '!r%< -lide it into the hori5ontal stoepipe that protrudes from the side

of the ocket -toe.

1 @ow you are L%G/ != BJ@M 8o outside and test your ocket-toe. Boil some water and see how fast it boils.
