rocket flames - rocket mass heater barrel prep

[thehappyinfidel2011]

Am I missing something? In every clip I've seen people are using a regular thin walled barrels which they mortar to the ground, and cheap ducting. How long would it be before its burned/rusted out and has to be replaced? Would it not be better to go to scrap yard and get a thick walled tank of some kind and thicker pipe?

@doughpat

seems it's to contain the paint,so as not to contaminate the air or have it flaking off all over the ground ?

love that after-burn flame !
