  • New pot stove

    I needed a new stove for my solo rig, so I decided to make another pot stove. I made one about 10 years ago, documented on the lamented WinterTrekking site, but that one is made from a 25 L pot and I needed a smaller one. The original pot stove has been great: lots of heat output, especially since I added a baffle, no rust and no warping.

    Started with this: a 6.8 L black enamel steel canning pot with a domed lid. The lid will form the bottom of the stove.

    Hole cut and 3" chimney port riveted in. I am using 3" galvanized duct, available at any building store, as chimney.

    Pattern for the baffle. The shape is complex because the baffle needs a step to fit the chimney port. The baffle is about 5 cm beneath the top of the stove, but the chimney port is close to 8 cm, requiring more space.

    Finished baffle with tabs bent in. This is what you would see if the top of the stove was transparent. I made the baffle hole in this shape thinking that it would distribute the heat more evenly. This hole should have about the same area as the chimney pipe.

    Finished door. I used a vertical sliding door because it gives a tight fit and allows adjustable ventilation low in the stove which makes for a hot and healthy fire. The door is the piece I cut out, which has a handy handle. The rails are folded from galvanized roof flashing.

    First burn, outside to burn off any zinc fumes from the chimney. Legs are made from an old folding chair.

    Stove in the tent.

    Tent with chimney.

    The stove weights 1200 g. The full rig including stove, elbow, stove pipe and legs totals 2.9 kg.
    I am very happy with this stove. It burns well, throws a lot of heat and has a very hot cook top. With the baffle it produces no chimney sparks. The pot cost about $25 CAD. They seem to last a long time and don't rust. Even the paint holds up.

    Some of the design for this stove was borrowed from Chimpac, a regular on the old WinterTrekking site. I used one of his stoves for years in this tent. It works very well, but I wanted something a little bigger (it was made from a 1 gal paint can).

    Looking forward to the snow!

    Why can't I see any pictures?

      Hi, no clue. They show up fine for me. Perhaps the administrator can help out.

      Edit: does anyone see the photos??

        Unless you posted pictures of a blizzard, I can’t see them either.

          Well I am baffled then. I followed the instructions and it took some time to upload the photos, which apparently no one but me can see. Sorry about that but I don't have any more patience to expend on this. If anyone is interested, I posted some photos to a FaceBook group.

            Thanks for taking the time to post. Sorry the photos didn’t work. I’m a fan of this kind of stove. I think many others would be too if they had a chance to try one. It’s a super efficient design. I’ve made one out of 10” round duct work. I’ll have to do a write-up some day.

              Thanks Snowbound. I remember seeing your stove on the old WT site. Yes I really like this style of stove. This is the first one I have made with a vertical sliding door and that is a real winner. Chimpac had some great stove ideas but his stove is beyond my ability to make.

                I cannot see the images either, it's saying invalid image file. perhaps were they copies from Facebook? If so, that may be the issue. I'll try to repair the post.

                  Yay! I fixed the photos!

                    I like that design a lot!
                    Old water bath canners and enamel stock pots pop up in thrift stores from time to time.
                    I see cheap stainless stock pots around occasionally too, those would make a good donor for one of these stoves too.
