I started with a copy of the Nov/Dec 2013 BackHome magazine, built a pocket rocket that ran pretty good in my backyard, and got to here. I have scanned quite a few titles and opened some threads. I have some questions.

#1. This seems like a pretty open community. I have penciled out, but haven't yet fabricated, a rocket stove that would be very much like the shippable core idea towards the bottom of page one. If my stove works, is it morally acceptable to just post the plans so anyone can make one; and then possibly fabricate some at a small profit for folks who don't want to build them themselves?

#2. Has tig welded stainless been tested to destruction thoroughly enough that no one is wasting their time with it anymore?

Briefly, I am planning to fiddle with a one bell system using a six inch feed with a ten inch outer barrel as a camp stove for Alaska sized hunting tents. My own wall tent for moose season is 16 x 24 feet and they come lots bigger. Good name in wall tents here: http://www.alaskatent.com/walltents.html .

I would like to make the stove light enough to transport to remote places strapped onto an ATV rack - I was thinking maybe sand could be shoveled in to the places needing insulation once the stove was at the campsite.

I'll go back to reading old threads now, thanks for your time.

Michael Scott : Welcome to Permies.com, our sister site richsoil.com, and a Big Welcome to the Permies Wood and Rocket Stoves forum/threads, with over 20,000
fellow members world wide, you should be able to come here 24 / 7 and find someone who wants to talk with you about what you want to talk about ! They bring to the
table, based on experiences and locations, widely even wildly, differing points of view. They will stretch your mind as you will stretch theirs !

-And there is always more information in our own 'Cloud' the pCloud that can be search via Google within Permies itself ! also available 24 /7 !

Your #1 plan perfectly describes the way things click around here, in other posts Paul Wheaton has offered to let people describe what they are doing, and with a proven
product tested (for a year ?) offer to let you have Ad help for an associates fee, kinda a 'from each according to their ability, to each according to their needs' thing! When
you have a product you want tested you will get help here !

Your #2 Is dead, mostly due to the freaky high temps our RMHs with additional refractory insolation can reach ! 2400*F + ! So far, the best explanation for steels failure at
high temps is best (My Opinion) explained in an article in Wikipedia ,called High Temperature Hydrogen attack, there is also buried in the explanation
details that point out the importance of pre- and post- Heat Treating of 'worked' steel for (relative) longevity !

A good name for conventional wood stoves is four dog wood stoves goto> four dog.com, when you build your Rocket in a tent share your experiences with us here, Pictures too!
If you had two identical RMHs one with a 55 gal barrel and one with a 30 gal barrel -for the magic that occurs To allow us to flow hot exhaust gases sideways 40', both barrels
have to give off the same amount of heat energy, counter-intuitively the smaller barrel has to radiate the heat energy at a Higher Temperature, something to think about in a
smallish double wall tent !

Also it is possible to set your barrel off-set from the center of your Heat Riser, thereby having a cold side and a warm side to your barrel, however,even if you were able to find
a sand sized pumice rock at your camping spot, you would find that the heat would eventually equalize between the inside of the Heat Riser and the outside of the Heat Riser
killing our high velocity air flow that makes our Rocket burn the wood at high temperature and efficiently.

If you could use a conventional heater,cook stove for a few days, at start of 'camp' you could bake a set of clay and sawdust bricks to make an insulated chimney for your Heat
Riser, but that would be a waste of 2-3 days 'in camp' and your technique would have to be well tested before you ever left for camp ! Come back here often, perhaps some
other Alaskan has worked this out, if not we can always spit ball it around ! For the Good of the Crafts ! Big AL!
