ANNNND I was considering a base of rocks at the bench tubes and a two to four inch concrete pour verses cob i.e I have a friend that has a concrete biz will this be a poor decision?

Great info all the "insulation" is a perlight/refractory mix if that aids in any picking of my design

How hot should the top of the barrel get in a properly working stove

Aww man don't tell me that so you are suggesting to use fire brick alone?

Right, she did but.... It may bite me later but I'm going to risk using the metal j tube it is 7x7x1/2 with the inside 6x6 heat treated steel and shouldn't do any thing goofy until after 2500 the length of the tube is a concern I have I didn't think it thru completely the center to center is 24 I'm thinking it should be 18ish when I made the pipe I made the distance from radius to radius 18

Sorry for the repete pics I'm having issues up loading

Thanks for the reply I do have more pics of this build I will send now and all of the metal is rated for 2300 is this going to be a issue for me later?

Ok I have bought the 4 disc video set from Paul,Ernie and Erica I just completed my first build and ran it last night outside on the concrete for my greenhouse and not sure if its working properly no granted I DO NOT have it completely sealed this was just a preliminary run should there be water dripping from the horizontal draft tubes,am I not getting enough burn in the catalist chamber?
