When I learned welding, one of the things I was taught was that you never never weld galvanized material without special respiration equipment. This is because when heated to high temperatures, the coating gives off toxic fumes.
I don't know what level of heat is required for that to happen but a wood stove can get pretty hot, and I don't remember seeing one made out of galvanized metal. Ergo, I'd err on the side of caution and stick with traditional materials. For what it's worth, if you look around in the country, there are old wood stoves to be had pretty dang cheap -- or even free, if there's one just taking up space somewhere. You may well need to remove rust etc. but the result could be awesome.
Regardless, a free/cheap older woodstove seems likely to be much less effort, safer, and likely to last longer... hopefully you can find such a thing in your area as an immediate solution, and move on to a rumford fireplace/RMH etc later on.

Interesting thread indeed Dillon.
I'm going to err on the side of caution concerning the galvanized metal. Though it might, "might" be useful under another stove as a cinder catch or something.
I was wanting to build the rocket stove but the 55 gal drum is just too much for the small area I have to heat. (12x14) It would just be in the way and take up too much room.
I'm looking at a couple other methods to the madness to heat a rock based mass, that way I don't have to burn so much wood.
I'm also looking at this little portable camp wood stove as a viable alternative. If all else fails, I'd at least have that.
I like the fact it has a water heater that attaches to the stove pipe. (See attached image). And they sell for $39 bucks on up. Averaging around $59 as a middle ground. I'm curious as to how well they would hold up over 4-5 months of continual use.
You've gotta fight it! Don't give in! Read this tiny ad:
