Where did you order your kiln from? This is also on my list.

Mine is just a 55 gallon drum with a lid and some stove pipe for a chimney.
I couldn't find a 35 gallon drum for the retort so I'm using a small garbage can.
These things were already on my property when I bought it, but if I had to buy everything out would cost $100 or less
Nice. So a lot like a rocket mass heater build? I need to research plans. We do have a 55gal drum.
There are similarities to an RMH build.
It's really simple. Holes at this top and bottom sides of the barrel.
A lid with a chimney.
A retort with a lid and 4 or 5 holes in the bottom.
I wrote an article on my website showing exactly how I made my retort. I hope it helps.
