I did not start to build a
RMH yet I am still researching learning and acquiring material I want to build one as a practice temp. unit outside then build one into a garage and later one in my house or a cottage etc. I do not want to duplicate efforts and waste materials. Do we have a list of all failed ideas for materials and another list of promising Ideas?
skipping the obvious stuff like aluminum
dryer duct core or reactor core for a nuclear sub.
What about thick reinforced
concrete coated on the inside with some kind of high temp paint? how about a chunk of well pipe? They are pretty thick and 6". how about pottery? Or will it not be able to handle temp changes?
Also how long does a 55 gallon barrel last would the top burn out?
should I get spare tops to replace every few years? maybe even a comparison of something like
55 Gallon barrel (untreated) barrel 1 - 2 years (top 1 year)
55 Gallon barrel (prepped old paint cobed off and replaced with high temp paint) barrel 3 - 4 years (top 2 years)
55 Gallon barrel (prepped as above but with special expensive high temp coating) barrel 5 - 7 years (top 4 years)
same could be done with core materials
