Staci - Great post at an opportune time as we are just starting our 6" rocket stove working off the same drawing here down in New Zealand.
I was just about to order the fire bricks, yes was going to use full ones for the riser as well!
Following the response and threads;
1. I will look at a cast riser, or at least split bricks.
2. I had not thought much about the transition to the flue, this looks a key ash clearance area and the attached thread invaluable. good access ash pan and smooth chamber required.
Questions;
1. Are you going to introduce secondary air into riser tube? I have seen some information on this but no drawings, just comments on a sketch.
2. I intend to install water heating tubes around the main drum to run a wetback radiator system in the house. I have seen pics on this, are there any issues with cooling the drum that much? Does anyone have experience on this?
