It is winter now in the high deserts of Az my RMH bench is dry, I get a rocket noise when the wood is in just the right way and it does draft, but the temperatures are very low (magnet temperature gauge) it barley gets to 300 deg. 90% of the time it stays at 250F or lower or about 100C this is on the side of barrel at the very top. Could my ash pit be too big and causing a problem with the burn? I have attached 2 pictures (I hope) that show the ash pit section any comment would be very helpful. TIA
Just in case pictures do not turn out.
Ash pit measurements 12+H at the barrel 24" across at barrel tapers down to 8" pipe about 22" long.
