I just checked the stove again for the dripping. Sure enough it is doing it now, even with pallet wood and 2X4 pieces, all completely dry from the barn, from a rack off the floor, been in the barn for years, never wet. I put in only three small thin pieces of my split cordwood this time, all with no bark and from the face of the stack near the stove, sure to be either fully dry or the driest that I have.
The stove had burned down to coals before I reloaded (so much for "+40 hours" on a full load, it's not even twelve hours, and the termperature control knob was set low, at the very beginning of the white band, as usual) and remember, the dripping only happens at the beginning after a re-load, then it stops, so there was no dripping since last night, and now it starts again after I re-loaded with wood that I know HAS to be dry.
Maybe no matter how dry the wood is, the stove still extracts moisture and it will collect and show itself at the bottom of that seam on the horizontal. Maybe the uninsulated two-foot passage through the wall is condensing the moisture and it runs down there. I understand that even a trace of moisture will rust this stove, so it must be stopped. I may stop burning the stove if it happens again with one more load of ALL 2X4 and pallet pieces.
