DIY alcohol stove



• Step 1. Cutting tube

  
  Firstly you need a spiral tube. For this is needed a copper tube with diameter of 8-10 mm and length of about 40 cm.
  

  Dont forget to treat edges with file to not hurt yourself with sharp edges

  
  

  


• Step 2. Twisting spiral

  
  Tube is need to be bended into spiral, and to prevent it for crushing, fill it with sand. Plug one edge of tube with wooden stick, fill sand and plug stick in second edge. Next find a cylinder with diameter 30-40 mm. Spray cans is the best idea, because there is a many models with differend sizes of them in your house (air fresher, deodorant...) Next step is bend tube around your spray can for 1.5 turn.
  

  

  
  

  Coils need be on some distance, it depends on size of flame and you can tune it with final step of making that homemade alcohol stove. Flame must pass between coils.
  

  


• Step 3. Wick

  
  Now it's time to insert wick. Wick is a cotton strip. Insert it in both edges of copper tube to the lenght of straight sector of tube. Also fuse needs to stick out to 20 mm from lower edges of tube. Thickness of wick is experimentally.
  

  If wick will too thick, diy alcohol stove will blow fire. So you need to make bigger jet hole (next step) or make thinner wick.

  
  

  

  
  

  


• Step 4. Jet hole

  
  Next step is to make a jet hole in tube. Size of hole is optional and gets experimentally. Start from diameter less than 1 mm, you can extend it. Make hole with an awl and hammer, copper is very soft.


• Step 5. Alcohol tank

  
  Now we need a tank for stove. Drill two holes in tank's cover and put spiral tube into it.
  

  

  
  

  You can use glass can, or handmade jar made of can.


• Step 6. Attaching tube

  
  Next step is hermetically attach tube to cover. It could be made by soldering.
  

  Dont forget to treat or scratch surface before soldering

  
  

  

  
  

  

  
  

  Connection between cap and alcohol tank must be germetically, because this diy alcohol stove will works only if vaporised alcohol passes only through the jet hole

  
  Fill tank with alcohol and thats's all, homemade alcohol stove is ready to burn!


• How it works

  
  Start heating sector of tube with jet hole with lighter or matches, or any source of fire. Tube is starts to heat and heats fuel in the wick. Fuel starts to vaporise and moves to jet hole, then taking fire. Now flame from jet hole heats spiral tube and process comes independently.
