So after an 8 month break, I am back to it. ALL/ANY help is appreciated.
3 questions now: (I tried to attach pics)
1) I have salvaged fire brick. All are dense type. Some are grey and smooth, others are more grainy/coarse and yellowish. I bought splits for the heat riser ($4.05/ brick was the cheapest I could find.)
Is it okay to interchange these types of bricks in the RMH?
2) Building the mock up riser and burn tunnel is a challenge already. I have a huge deficit in spatial relations/orientations. Feeling defeated before I begin. I am going with a 6" system (in hindsight 8" might have been easier, but I already have the 6" stuff).
I am experimenting with 5"x6", 5.5" X 5.5", etc. dimensions, keeping CSA of 30. No matter what, I have a gap too narrow to put in another split or a full brick in the area between the feed and riser.
3) What determines the height of the burn tunnel?? My stats so far: 48" riser, 23" burn tunnel, 16" fuel feed
