My long-awaited Backcountry Boiler (Supreme) finally arrived last week.
Took it out yesterday for its second burn and grabbed some pics in the process.
Boiler in its sack.
Out for show.
I took all of a minute grabbing this handful of sticks out of my yard. More than enough fuel for a burn.
Used the Becker BK-2 to prepare some fatwood shavings for a clean ignition.
Loaded up the chimney with a few sticks.
Burn from above.
Within 4.5 minutes, I had bubbles. Within 6.5 minutes, I had a rolling boil that was actually boiling over.
I'm exceptionally pleased with performance.
With a little fatwood and a handful of found fuel, you can get 2 cups of cold water to boil in under 5 minutes.
The stopper functions well, so you can carry in your water for a hot drink on a hike.
I'm still getting the inside of the boiler clean though. The vessel contained some metal shavings from the etching process, and the directions called for hot water rinses and a dump of the first boil.
However, as you can see in some of the pics, little shavings are floating to the surface even on the second boil. Third boil (later)? Not so much.
Still, I'm going to give it 5 or 6 more burns and examine the water in a clear glass at that point, just to be sure I'm not getting any extra minerals.
Great product. It was a long time coming, but it was worth the wait.
I'm also supposed to have a "Firefelt" on the way.
Basically a fireproof fabric you can soak in denatured alcohol and use whenever no sticks or twigs are handy.
Devin Montgomery designed this aluminum stove based on some really old chimney kettle models. He took extant design and tweaked it nicely for a backpacking stove.
It all started in an old Backpacking Light thread back in 2009. You can read about his design here here: http://www.theboilerwerks.com/about/
Sadly, a British individual ripped off his exact design, only changing the material, and started putting out the "mKettle" (even the name is a rip-off of Devin's last name) in stainless.
