Hmmm , I attached a picture and I can see it on my post. Not sure why it can't be seen. Any help?

Just wanted to share my second attempt in the rocket stove world. It is powered by broaudio's super hot 6" j. I ordered his plans and built my core. The plans were perfect. My stove is a heater plain and simple, designed to give me fast heat out in my workshop. I gotta say that my first couple burns are very promising. Zero, meaning cold, to 600f in under 30 minutes on 2 loads of sticks. The second, or top barrel really surrenders the heat quickly and radiates very well. I'm pretty sure this isn't an original idea but I haven't run across it yet. Let me know your thoughts on this idea folks. I'm all ears!

Yes Glen , I guess I was grasping at straws because I am a metal worker. Next question, when you folks talk about split firebrick are you referring to the brick that would come in a wood stove? The 1 1/4" heavier brick? I have s bunch of those and that will become plan A now if they're suitable. It'll be wrapped in ceramic blanket that I already have. Again thanks for all of the good feedback!

Thanks Jonathan, that's the kind of info I'm looking for. Do you know of any affordable/available alloy that would work or how long it would take to degrade if applied to regular carbon steel at rockety temps? I got 3 heating seasons out of uncoated .250 wall steel before the flaking happened.

Hey folks, I wanna beat this dead mule a little bit more. Question, would ceramic paint work in a metal riser? Some of these coatings are rated for 3200F and higher. I understand that the interior would be very smooth but I believe that could be worked out by adding some very small restrictors to encourage the mixing needed to burn all or most of the stuff we want to get burned. Has this been tried before? Please share your thoughts and ideas. Thanks

I guess that I am still learning about these awesome heaters. I just ordered Erica and Ernies book and also Ianto Evans book on mass heaters. Maybe that'll take some of the guesswork out of what I want to do. I'm fiercely independent but will accept good knowledge and others expertise when I need to. Good luck with your build!

My steel core burned out. I had my riser insulated with 2" of ceramic fibre blankets and it heated my uninsulated shop wonderfully but after two heating seasons the steel is disappearing. Mine was 6" square hss and 1/4 inch thick. It's now toast. Next core will be firebrick or ceramic board or a combination of both. My rocket was a simple heater with no mass. It was miserly on wood consumption and I loved how it worked but the guts need replacing. Will also be adding a pebble style bench to get max effect from the fuel.  Hope I can get it right!
