in my books 0.8 mm is ultra thin. always use them.

[@foxfish7115]

Yes I got that wrong, the ones I use are 1mm

Excellent, thanks for sharing. The vermiculite board remains in amazing condition. Were those ones painted with zirconium slurry or are their surfaces raw? Regarding oil in the drum, after draining, the remaining oil can be efficiently removed by sloshing a few litres of water with a couple of hundred grams of sodium hydroxide (caustic soda) powder around the inner surfaces (they react to form a soap which accelerates removal). I love the longer video. Thanks again.

Thanks, yes the Skamol vermiculite is just as it comes and seems to be lasting very well, the thing is, I will probably build something different next year so it only has to last one season! I should of washed out the barrel with more care but, there never seems to be enough time in the day…… thanks for watching

Beautiful! What's the restriction % at the vortex inlet? Don't you get unburnt smoke with all air closed? I'd leave the tertiary open, at least partially

[@foxfish7115]

There is always some air, it gets in around the front window and the sides of the top glass, I think i put the restriction size in the last video, I will have to check myself!

[@ing.pagano]

@@foxfish7115 of course, but that's providing primary air. In my understanding, restricted primary air controls the rate of gassification, but you still need secondary air to combust the produced gas

[@foxfish7115]

⁠@@ing.paganook I am no expert, just having fun, perhaps I am just burning the wood very slowly then? What I can see is the smoke coming out of the wood and catching on fire above the wood, there are still some flames appearing from the wood as well, so maybe not a complete gasification ?

[@ing.pagano]

Maybe it found a balance to burn clean... How did it look inside the riser?

[@foxfish7115]

@@ing.pagano when the stove is very hot and has a bed of coals in the fire box, if the main air supplies are then shut down, there is nothing to see inside the riser, it will be dark as all the combustion is happening inside the upper part of the fire box. I will try to show how it works in the next video.
