The Supercat Ultralight stove and Firebucket windscreen

Thanks to Jim Woods (  I had a great ultralight alcohol stove to use for my hike when I decided to start hiking with a stove to heat my food.  The stove, windscreen and fuel bottle together weigh less than 25 gm.  (an ounce is 28.35 gm)

Here they are on a scale:
The stove, 6.37 gm.

Fuel bottle and foil windscreen.  17.44 gm.  

Jim Woods' Firebucket
Jim also has another innovation I made but didn't take.  He conceived his Firebucket as a better windscreen for reasons enumerated on this page.

I made a Firebucket.  I haven't used it in the field because my triple fold foil windscreen did the trick on a stormy night under my tarp. 
For my bucket,
1.  I left out the bolts and wingnuts (which I'd surely lose) in favor of a fold on each edge of the joint, that work like the caldera cone's joint.
2.  I used an inverted empty 5.5 oz aluminum cat food can as the platform for my super cat stove. I can easily light my Supercat without the Firebucket getting in the way. I use another 5.5 oz can as a snuffer.
3.  I cut the flashing so my saucepan would sit on the supercat on a 5.5 oz can.  The Firebucket's diameter was just small enough to support the saucepan (with 3 cups of water) without the supercat underneath  I could use a penny stove on the ground below the stove.  I can put out the flame on either stove by dropping an inverted spare 5.5 oz can over its top.
4.  The Firebucket weight:  51 grams = 1 3/4 oz

The inverted 5.5 oz cat food can serves as a stable base for the stove.

My Evernew saucepan on the stove.

The saucepan with nothing underneath, the top of the Firebucket holds the rim of the saucepan on the right.  I wanted it to fit a little tighter than it does for just a smidgen more confidence that the lip on the right won't slip.
