Hello everyone, new to the community and here to share.
First off, I would like to introduce myself. My name is David I am a 28yo welder and metal fabricator living in Northwestern Minnesota (it can get -30F to -40F quite easily here). I spend most of my time fooling around with stuff and building solutions to problems. Recently we had a storm that took down a few large trees on my property and after cleaning it all up I was left with a massive wood pile that I didn't know what to do with. I also had another problem, propane gets expensive and trying to keep the shop from freezing can take a few tanks. One day of one youtube excursions I stumbled acrossed rocket mass heaters (and a lot of your videos ). After quite a lot of digging around, I decided to build one. I found and old propane tank in the farms scrap pile, a 5"x1/8" ERW riser and 5"x7"x1/4" burn tunnel and got to work. Even though the riser isn't insulated and it has a 2" headspace, I am very happy with the results. I fired it up today with 8 1.5"x1.5" pine wood stakes, I had it up to 100F in the shop before I couldnt take it anymore and opened the doors (it is 40F outside with snow on the way)
Unfortunately, during this time my big welder broke and I had to use my little welder. This took a very, very long time and didn't look as nice as I wanted it to, but since the was just a test to see how well it would work I didn't really care about how it looked. Also, in the future I plan on removing ALL of the paint before starting it, man that stank when it got warm.

I discovered today that my shop camera can pick up infrared heat, there is NO visible light coming from this barrel AT ALL. The pinkish hue from the top of the barrel and the firebox are actually invisible infrared light.
David : Many Types of Cameras are capable of this function, and it is possible to even create 'night vision goggles ', I believe a good place to look for more information on this
would be at - ' Instructables.com ' - I just learned that many of these can show which circuits in a circuit panel box have been being used/ worked hard by an I.F. glow !
For the craft ,think like fire, flow like gas, Dont be the Marshmallow,Your comments are solicited and Welcome PYRO - Magically Big AL !
Late note : David, did you have any special reason why you went mass-less ?
Viz : The paint burning off, yah really Nasty, there is as good series of Videos at our sister site richsoil.com Click on the (Rocket Mass Heater) 'more info' icon and watch the
series, there is a real good way shown to deal with the paint issue and lock the zinc onto the stove pipe so that that is not an issue, though a Spanish R.M.H. builder puts an extra
final overwrap of household aluminum foil- shiny side in- and says his way is even better ! Out side of that, I don't watch much R.M.H. stuff on U-Tube Land, there is a lot of crap
out there ! A. L.

There was really no 'reason' I went massless. The main reason I built it this way was to dump at much heat as possible into the shop efficiently and quickly (which it does very, very well). There is a vertical dead space behind the RH that I have been thinking about using as mass, but I am not 100% on that yet. The biggest thing I can think of is just simply the lack of space that I am willing to sacrifice, it is pretty valuable in a 18x24 shop.
