Making a portable rocket oven

Hello, dear readers and homemade products!
One of the unusual, but already well-known designs of small ovens is the so-called “rocket” oven. This site has already had several different ovens of this kind, but they are quite heavy, and suitable for use in a country house or a personal plot.
In this article, the author of the YouTube channel “KUI Iron” will tell you how he made a compact “rocket” oven for cooking.
Making a portable rocket furnace  Making a portable rocket oven The master will make this homemade product from relatively thin, millimeter stainless steel, which will require a serious welding machine ( TIG ), and skills to work with it. Of course, such a furnace can be made from another, thicker ferrous metal, which will make it possible to get by with an ordinary welder.
Materials necessary for home-made.
– Sheet stainless steel (0.8-1.2 mm), pipe < br> – Welding rod
– Masking tape.
Tools used by the author.
– Dremel
– Caliper
– Bulgarian
– Welding machine
– Screwdriver, riveting nozzle for screwdriver
– Scissors for metal, pliers, nippers
– Vise for CNC – – Roulette, marker.
Manufacturing process.
So, the material for this furnace will be trim chimney pipes made of stainless steel with a thickness of 1 mm.
In addition to the base cylinder, which will serve as the body of the stove, you will need two flat rectangles of the same material. The master decided to make them from the remains of a pipe of a slightly smaller diameter.
Making a portable rocket oven  Making a portable rocket oven To cut exactly two pieces of pipe, he glued two rings of masking tape to it, along the edge of which a grinder is cut.

The bottom disk should go inside the case, and the blank for the lid should have a margin of about 20 mm at the edges. For cutting discs it is more convenient to use metal scissors .

Having removed the dimensions with a caliper, the contours of the cutouts are marked in the center of the lid and bottom.

Do portable rocket furnace Making a portable rocket furnace Making a portable rocket oven It is quite difficult to cook thin stainless steel, and the master uses a TIG welding machine for this.
After cleaning the seams, they are practically invisible.
Making a portable rocket oven  Making a portable rocket oven A series of cuts are made along the perimeter of the lid, peculiar petals are formed.

Making a portable rocket oven  Making a portable rocket furnace The author constructs the stand from several scraps of the filler rod. This is also stainless steel, the diameter of the bar is 2 mm.

Making a portable rocket oven  Making a portable rocket oven Making a portable rocket oven  Making a portable rocket furnace In the central part of the firebox, you need to place a strong mesh in the form of a cylinder. It can also be replaced with a tube with many holes.
The author decided to make such a mesh on his own, welding it from the same filler rods.
First, you need to bend two rings (using the tube as a mandrel) and weld their joints. < br> Making a portable rocket furnace Making a portable rocket oven Making a portable rocket furnace Then both rings are connected rods of the same length (the same as the height of the furnace).

Making a portable rocket furnace Making a portable rocket furnace The principle of operation of the furnace is similar with this method of setting fire to a log split along a log.
 Making a portable rocket furnace Making a portable rocket oven  Making a portable rocket furnace Everything is ready, pellets (compressed pellets from wood waste) will serve as fuel. They fill the firebox to the very top.
By the way, the filled stove can be safely transported – you just need to fix the lid.

Making a portable rocket furnace Making a portable rocket oven To ignite the stove, you need to fill the void inside the grid with large sawdust or paper, and set them on fire.
Making a portable rocket furnace Making a portable rocket oven Making a portable rocket oven Making a portable rocket oven The oven goes into operation within a few minutes. The heated fuel begins to emit flammable gases, which are carried away due to the thrust up the channel.
As a result, the author's oven worked for more than three hours (with the damper fully open).
Making a portable rocket oven Making a portable rocket furnace Making a portable rocket oven Of course, the design can be improved and modified, for example, by installing a windscreen. It is also advisable to make the stand in a slightly different shape so that it (in this case, the cross) is not located above the hole and does not fall inside the flame.
 Making a portable rocket furnace Making a portable rocket oven Opening or closing the shutter , the flame strength is perfectly regulated.
