I will show you how to build a Pocket Rocket Stove.
If you don't know what a rocket stove is, have a look at "" or search at Youtube where there are tons of very good videos to get inspiration from.

Step 1: Material List

Picture of Material List
Materials needed:
1x oval bucket with lid
1x stove-pipe 120mm x 1 m
1x stove-pipe 130mm x 50 cm
10l hydro clay for hydroculture-plants
2,5 kg chamotte mortar

Everything costs about 35 EUR

Tools needed:
hammer (optional)
oil (optional)
marker pen
metal scissors
bucket (for mixing the mortar)
bucket with the same shape as the bucket for the stove but slightly smaller
plastic bag

Step 2: Mark the Holes

Set the pipes on top of the lid and draw around them with the marker. Then drill a hole in the middle of each circle.

Step 3: Cut out the holes

Make star-shaped cuts in the lid. If your scissors don't fit in the hole you can enlarge it with a spiky hammer. Then bend the triangles down, so the pipe fits into the hole. Cut as many triangles as possible (more than shown in the picture). The smaller they are the better you can bend them and the better the pipe will fit.

Step 4: Insert the pipes into the holes

Insert the pipes in the holes as shown in the second picture. The wood feed should be about 4 cm above the bottom.

Step 5: Make the bottom of the stove

When you have finished the lid you start with the insulation of the stove. It helps to keep the heat in the stove to make it more efficient and it protects the thin metal bucket from the heat and increases its durability.

Mix the mortar with water so it has the consistency of ketchup. Fill the bottom of the bucket with hydroclay ( about 2 cm high) and then pour the clay pearls into the mortar. Mix it well and pour it back into the bucket.

I really like your design.
But it seems like it might get clogged with ash at the bottom of the burn pipe?
Or it might be hard to start the air convection through the larger pipe?

I had no problems with the ash yet.
But you're right, you have to be very careful when you start the fire, to prevent getting a backward-draft. I always push some sheets of paper down the chimney and light them to start the draft in the right direction.

Next time I definitely make a 'real' rocket stove and not a pocket rocket, then you don’t have these problems.

As far as the smoke drafting the wrong direction, just blow the feed tube like you were blowing out a candle. That should get the air flow going in the other direction and the heat will do the rest.
