chimney through rounded metal barn

Hello
I have been reading up on rocket stoves, RMH's and wood stoves but my first question is can anyone help me with a chimney route? I have a quonset hut style barn that is galvanized steel and has ridges in the sides/roof after about 4' high. It looks like this http://www.americansteelspan.us/SModels.html
I was thinking a RMH would be great because I could vent out the 4' and lower wall but with its limited use a pocket rocket or traditional wood stove would most likely provide better fast and now heat. However do I go vertical and just caulk the heck out of my roof or go through the side then up (wasting all my heat?

The barn is about 25' x 40' with a 15' ceiling in the middle. I'm looking to take the chill out of a NW Ohio winter not hang out in shorts and t-shirts away from the house. Unfortuantly the building runs north/south and my end walls are plastic sided and have garage and walk doors.

Any suggestions?

Look for a "dead soft" flashing. It is extremely pliable and made to form fit (with a rubber mallet) to metal roofs. http://www.ventingpipe.com/index.cfm?page=search%3Abrowse&searched=main%3Ahome&term=dead+soft+

ETA: Here is a youtube from a place I normally trust for stove issues:

Thanks, I had only seen the 'regular' flashing that didn't seem to be able to be worked like that.

Here are pictures of the barn (hopefully). Do you think that kind of flashing would really bend into all the grooves?

I have seen it done. I would have about an 80% chance of being successful, but I tend to use brute force too much.

Another option is to get someone who is good at welding sheetmetal and weld it in. You would have to deal with the galvanizing but it wouldn't leak.

A Bowen : Do you have the same rectangular vent on both ends of your Quonset hut,Like the one directly under your outside light ! if yes you can certainly sacrifice
the one on the other end, the running Rocket Mass Heater R.M.H.will suck in a matching amount of air to what you use .

My only other suggestion is to call the 800 # you got and ask them ! Hope this helps Big AL !

Whatever you do, don't weld galvanized metal! Don't ask your friend to weld galvanized metal! Galvanized metal gives of toxic fumes and you WILL get very sick if you breath the fumes. It's called metal fume fever or galvanize poisoning and you'll feel like you have the worst flu you've ever had and you'll wish you were dead.
