I want to build a rocket type stove/mass heater in a small, portable package that I can take camping in a wall tent.
I am new to rocket stove tech and plan to build a couple of small stoves for cooking before tackling a larger scale heater.
Currently my idea is to construct the feed tube, combustion chamber and chimney out of black stove pipe. Looping the exhaust pipe through a box filled with sand/clay mix then exiting up through the stove jack in the roof of the tent.
Are you asking if anyone has tried to build a rocket stove from stove pipe? Only every welder and tinkerer who has ever read about rocket heaters... stove pipe, tanks from hot water heaters, propane tanks, you name it sort of metal. It has all been tried. It all eventually fails because metal (even stainless steel) can't stand up to the high heat which a well-tempered fire produces.
I am a partner in Dragon Heaters. By next week, we will be shipping a 6" portable metal box which would work great in your tent. In our case, the metal box is not the combustion system. It is isolated from the cast refractory burn tunnel by several inches of perlite/vermiculite. If you don't like ours, you can make your own from the 4" or 6" model. We have instructions on our website, www.dragonheaters.com.

Ianto Evans' Great Book 'rocket mass heaters $15, with `100,000 rockets build world wide most were built following 'The Book' and 95% of the First time Builds
(that worked) were made following 'The Book', there is STILL no other book in any language with more rocket stove family information! (and I don't make a dime!)
If you want more technical information about why Iron and Steel can not hold up to the combustion temperatures of wood in a modern rocket mass heaterRMH, I can
suggest going to> Wikipedia to look up their article on High Temperature Hydrogen attack , it even explans why pre and post theta treatment of cut and
fabricated steel is important ! For the Good of the Craft ! Big AL !
