Today we are building a “batch-loaded, inverted down-draft gassifier” wood stove out of old tin cans.
But before I could do that we had a few chores to complete, not least to go out and find a suitable mesh for the bottom of the burner. I found something – a shower strainer for $1.68. Once the chores were out of the way I started trying to work out the best way to build my MK-I stove, which kept me occupied for a couple of hours. The reasons for trying this are (1) it’s fun, (2) carrying a stove and fuel adds around 2-3 lb to my pack. A stove like this should weigh around 4 oz, and it should also be smaller than the stove, and (3) did I mention it’s fun? Anything involving power tools and fire has to be. In the picture I’m lining up the outer casing before drilling the air inlet holes.
With a favourable (ie 40°F) temperature predicted for the night, I set up the solo tent in the backyard so that I could do a ‘backyard test’ of my new sleeping bag. Before retiring to my tent we tried out the stove. It was not a complete success, it seemed that the ash was blocking the mesh in the bottom of the burner, causing the fire to die out through lack of air.
With plans to modify the burner in the morning, I went to bed and spent a very toasty night in my new GoLite 1+ Season quilt. I was almost too warm. Contrary to the earlier forecast the overnight temperature only dropped to just below 50°F. The lowest overnight temperature in the tent was 48.5°F – aren’t modern electronic gadgets wonderful! We have a max / min electronic thermometer called a ‘Dangler’, we found for $10.
My conclusion is that with a base layer the bag ought to be good for use from around 35°F. Which considering its 1 lb 4 oz weight and 8″ x 6″ stuffed size is pretty darn good.
