The endcap allows you to chop the quart can down to the height you want. I use an IMUSA four cup mug and wanted a stove that fit inside of it. So I spent about an hour and came up with this. It has a 3.75" tall base compared to the standard 5". It is my new 'go-to' stove, it burns amazingly well and is a lot lighter and more functional than the larger versions. I have had a lot of success with it this far and plan to take it on my future trips. One thing to note, is that I discovered that a stoke tube really helps kick this stove into wood-gas mode really quickly. I made it from simple refrigerator water line and a brass coupler.

The Stove in action:
My biggest concern with a wood stove on a backpacking trip is wet wood. I plan on taking a small alcohol stove along with it on days I don't want to light a fire. However, I was testing one day in a downpour and was very surprised with the results. It started downpouring as I was trying to get it lit. So I ended up trying to start the stove with wet dead fall in a pouring icy rain with a 5-10mph gusting wind, needless to say it was less than optimal. The stove smoked a lot and never really went into gas mode much longer than a couple minutes. After about 25minutes I got annoyed and decided to put it away for a better day, and as I lifted the lid on my pot I realized it was boiling. I don't know how long it had been boiling, but it sure didn't look like the stove was doing anything, it was just into charcoal mode. So it was a nice surprise, one that would work in crappy weather if I give it enough time. I am going to try to work on a windscreen, I am thinking about trying a windscreen that anchors into the ground with some light stakes instead of actually attaching to the stove.
