Hi everyone, new to the site and to RMH. I have watched and read about everything thatvthere is on RMH, i just mocked up the core out of full fire brick and tested it several times. That works great. I have a 55 gal drum to put over that and so my next question is this: what is the best method of putting that on and then how do you put on the exhaust out of the bottom? More info: i have the lid and lid clamp for the barrel, was thinking i could use them on bottom, cutting the lid to fit the fire brick riser, and then mount than and the retainer to the core, thereby allowing easy access to the riser for cleaning etc....all input appreciated!!! Thanks
