Outdoor Cookstove with TEN BRICKS

I plan to reproduce this stove with much larger concrete CAP BLOCKS.   I wonder if the length, width, thickness ratios of the concrete blocks
are the same  ?

I will be looking for two approximately eight inches long pieces of steel rebar or small steel pipe to set over the fire to hold the cooking pans so that the flames can blow by the bottom of the cook pan.   If the pan is large enough  a few rocks placed on the bricks and under the pan should work.

Hey Scott;
Next, try using slimy mud between each brick and then coat the whole outside with mud; it will work even better.
Clay bricks will work fine.
If you try concrete, beware that it will crack or even burst if the wrong materials get superheated.

This is an L-Tube design; you must keep pushing your fuel into the fire.
Play some more with bricks and try out a J-Tube.
After you try that, then get firebricks and try out a Batchbox...
And before you know what hit you, you will have caught the RMH bug...
After that, you may find you are an apprentice Rocket scientist.

Looks like they're using some sort of spacer on the back wall of the chimney. If you did the same thing at the front, you'd only need 9 blocks.

You're right !    Good eye.   I am disappointed that I did not see that.       And further to carry that through with reducing by one overall  brick !
Genius perception.  I want you on MY team.        I was thinking that I would want to extend the height of the chimney by the width of a brick to increase the upward suck or heat draw .... ( more rocket effect )  and that might involve cutting or breaking a brick or two to make it all fit.

Regards concrete block.   I have learned that the culprit is that concrete absorbs moisture  and when heated will break apart from the steam generated internally.    What helps immensely is to always cover the concrete blocks and never let them get rained on.   They may not last indefinitely  but they will get you through  a couple of good fires.
