I'm hoping someone will be so kind as to help me with a math/wood moisture question that I seem to be unable to solve. I seem to remember years ago reading about a way to calculate MC from weighing and then oven-drying wood, but I can't find the thing I read before.
I bought some soggy red maple back in the fall and brought it inside, where the RH was ~40% at the time and has been dropping since. On December 30 it seemed to feel fairly dry to my hand, so I took a low-value piece with wane and cut off the last 16" or so. I weighed it at 554 grams right after cutting it off the parent board. Then I put it on top of the wood boiler and weighed it every few days.
1-1 538g
1-3 526g
1-6 524g
1-8 524g
It seems that it has stopped losing weight, so I imagine it may be as dry as it will become. The top of the boiler is very warm and dry and there is good airflow in the boiler room due to the air intake fan. Are there any conclusions I can draw from these numbers about how dry the lumber in the stack may have become as of the 30th? I'll be very grateful for any assistance.
