Chimney cap

 The coolie hat chimney cap I built for my PROPANE TANK WOOD STOVE lasted all of two years.

Galvanized sheet metal . . . yea POS . . Time to solve that problem .
A scrap piece of expanded stainless steel sheet I had left over from another project gets rolled into a cylinder .
An old aluminum non stick wok that lost its non-stikedness minus its handle
Three bent up L's pop riveted to the pan and bolted to the expanded SS sheet cylinder
There , that should last a bit longer than a couple years .
Hows that for rolling in dough Mr Filthie-cus?


  1. Goddammit!!! How did I miss this?!?!? Somebody should be FLOGGED for their negligence!!!!!

    When you say you rolled it... was it from a flat sheet??? How did you do that!?!?

    And did you make the stove too?

    This kind of stuff drives me crazy. I should have spent more on tools in my younger life...

  2. Yea the expanded SS sheet is fairly easy to roll, I just set a piece of two inch black pipe in my vice and hand bent it into a cylinder over the pipe. Took all of ten minutes.
    Yes the stove I built out of a propane tank about eight years ago.
    The three chapter account is here

  3. No, M, I am talking about that shower cap on the flu - did you make that, or is it just the bottom of an old propane tank?

    I know guys that can do compound curves on metal and the put me into a jealous rage. Whadda they call it? An English wheel? The aircraft home builders do it all the time and think nothing of it... and I know darn well I couldn't do it to save my life...

    1. The cap is just an old wok frying pan minus the handle.
      Never messed with an English wheel. Best I can do is beat on a piece of tin with a ball-peen hammer and you know he mess that makes.

  4. Interesting you went out a window to vent your stove. Better I think then cutting a hole through the wall. You can still see out. Do you remove it Mike during the summer? How do you insulate the lower half where the flue comes through?

    1. Sorry about the delay, I never got notified about your comments. Blogger is weird that way some times.
      Yea that's in my garage and going through the window was the easiest option. If I had gone through the wall there would have been other heat shielding issues to deal with. As the siding is vinyl that would have been an issue as well. Directing the pipe out and away from the building through the window was the easiest.

    2. I don't remove it during the summer as it would be a bit of a hassle given the set up, but It probably would extend the life of the lower sheetmetal flue that rusts out every two or three years. The newer stainless steel vertical pipe is actually a scrap of chimney liner I found at the dump and that is holding up nicely.

  5. Another question, you don't have to extend the chimney three feet above your ridge line?

    1. I just replaced the lower sash in the window with a piece of plywood with about a 12x12 inch cutout in the center. I covered that cutout with a piece of 1/8th inch aluminum plate though which the stove pipe runs. Works just fine. Not really that much to look at out that window anyhow , just my scrap pile. There is probably some rule about needing to go above the ridge line but this works fine and gets plenty draft. It burns hot enough that you never really see smoke coming out of it other than on starting it.
