Rocket Stove

 So I called up a local steel place and explained what I was building and what I needed.  He said he had quarter-inch 6" mild steel square tubing in some rather short lengths left over scrap from a job.  Showed them to me and charged me $30.  They were 36", 24", and 18" respectively.

Did some cutting and grinding at home, but did the welding at school.  The legs and bottom cap are some pieces I rescued from the scrap bin.

Painted it with High-Temp BBQ paint.


The hole in front is covered up with another scrap piece.

Drawings and measurements
Stove in Action.  That's a dura-flame in the fuel magazine and the flame is burning downwards...

After a few firings using a Dura-flame log, results are rather good.  Body got hot enough to glow a dull red, so I'm guessing  in the ballpark of 600-700 degrees F.  Flame shoots out about 6-inches from the top of the stack, so considering the burn chamber is about 20" and a 30" stack, that's a 4 foot flame.

Future plans:  A 55 gal metal drum for a heat collector and some Fiberglass tape to insulate the body and the stack.  Why?  I'm going for portability, so wheels will eventually be stuck to those stubby legs and it will be moved about wheel-barrow style.

  1. One thing I learned in life is to love what makes you happy and to cherish every moment you spend with your family, friends or love ones because everything that we have now on earth is temporary. Well, thank you for inspiring us with your great art work.
