So I bought an inexpensive moisture meter on Amazon and used it last night to check several of my DNA-treated bowl blanks, plus just about every other chunk of wood I have laying around.

The box elder bowl that I mentioned in my original post that moved so much shows about 18% moisture; all of my other blanks that have been drying for 3 weeks or more were at 16-17%. The cherry bowl that moved a little during second turning was also at around 16%.

Other hardwood lumber (kiln dried, I think) was at 10% and a few raw logs from a recently cut maple tree showed 25% or more at the ends (treated with anchor seal) and 50% or more on the sides when I poked through the bark. So the readings seem reasonable, though the meter claims an accuracy of +/- 3%.

So for those of you who use a moisture meter, what moisture content do you find your dried bowl blanks have when you do your second turning?
