Hi Tengu
Looks like you have made a decent sized Buddy stove there. I make them in differing sizes from 'T' light size up wards.
Fenlander taught me how to make them and this is his description of making one:
Buddy Stove
A buddy stove is a great way to carry a backup stove for boiling water and cooking.
To make an emergency buddy stove you will need:
1. A Maya dust, Nikwax type tin or even a T light candle
2. Some corrugated cardboard
3. Candle wax
Cut a strip of corrugated cardboard long enough to fill at least half the area of you tin (this will act as a wick).
Ensure the width of your strips are slightly less than the depth of your tin.
Roll up the cardboard and place it in your tin, allowing it to unfurl.
Melt some candle wax and pour it into the tin, ensuring all gaps are filled to just below the level of the cardboard.
To use you buddy stove, place two or three stones around the tin as a pot stand, then ignite the cardboard wick. When the flames have spread along the cardboard, place you pot on the stones to cook. When you have finished cooking, use the tin lid to snuff out the flame." End Quote.
Personally I find that with a 'T' light candle version that it will burn happily for 20 or so minutes before the wax is used up and the wick starts to consume itself. To prolong the life of the stove keep a small bag of chipped wax that you can feed into the stove to top up the wax. A 'T' light version will boil up a couple of cup fulls of water easily if properly set up.
Bear in mind that this type of stove will build up a lot of soot on your pot which needs to be regularly scraped of. For ease of cleaning I have heard it recommended that you wipe the outside of the pot with washing up liquid prior to using the stove. Seemingly this makes it easier to remove the soot though I have not tried that yet.
Hope this helps.
