Nimblewill Nomad's woodburning stove

In looking for more info on zinc vapors I found this stove:

Here's an excerpt from the first paragraph of text on the page:

During the latest FTA Conference many of us had a chance to meet 
with Eb "Nimblewill Nomad" Eberhart. Eb had a chance to talk to us 
all about his amazing backpacking trip from Key West, Florida to 
Cape Gaspe,Canada; 4400 miles, 10 months. During this trip Eb did 
not carry any fuel. Instead he used a simple metal stove and burned 
leaves, bark, wood and other natural fuel to cook his meals. This 
design is based on the stove he used during his adventure. 



There was a comment about using galvanized steel also here is the 
text:

The directions mention the use of galvanized steel. The 
galvinization process coats steel with a thin layer of zinc metal as 
a way to reduce oxidation (rusting) of the steel. It should be noted 
that this zinc will be liberated from the steel surface when the 
stove is new due to the heat of combustion, producing a toxic vapor. 
Welders are familiar with this phenomenon, known as 'zinc vapors'. 
Among other problems, it causes a severe headache.
Thru-Hiker does not recommend galvanized metals, but if you do use 
it in your project or aren't sure, make sure to burn off all the 
zinc without inhaling the fumes before using it to cook with. Or 
better yet, stay away from galvanized metal altogether. You can get 
plain sheet metal at hardware stores (like the Home Depot) cheaply.
