I will dig through the photos or take another as all pretty simple. have had blues for the last 3-4 hours on Blaschack tonight. Without secondary cracked would have all gone up the chimney. I have to night blues that started at around 4:30 and close to 9 and still going though a bit shorter but still free heat will say too much secondary blows them out so does not take much beyond designed in with holes drilled around fire pot. I have found contrary to windy hill that a good poke down from the top only on the front and back edges of fire pot knocks a bunch loose. The shake and rake grates with greatest effort on front and rear of grates as center clears easily.
I have had mine up to 740 for a short time and DCrane told me to stop that as will take it to the graveyard at least the fire pot. I consider 600 last resort now but it will become a clinker factory in my experience. I have settled on trying for 300 to 500 depending on weather and will sneak to 600 for a short time if really cold out or somehow fell behind but the as I said a clinker factory and a shutdown and clean out coming in the future.
As stated I have found the grates will shake the coal bed and collapse the ashes to the bottom more or less but without working the bottom of the grates it is going nowhere and will only fuse to a clinker. Without working front and back edges of fire pot clinkers again at least with mine as that is where I find at least 50% of ashes.
Just my take on this stove but no reason to change so far. It heats well wastes little that is my job from dropping too many coals when clearing grates. If I bought a BB with the prices it is a 10 year payback and don't see me doing this in 10 years as dead in 15 if insurance actuaries and cardio doc have the slightest clue and ok it that my fate. I still get to see my grand daughter grow into a delightful young woman get to take her fishing and teach her how to shoot so never afraid for her safety. I can live with that.
