Approx. Sept. 2001 I had some newly cut trees (Fir, Ceder, Alder) cut into lumber. Stacked all w/stickler boards. This summer the moisture content was down to 8%. We have kept it covered at all times. Went to use some Alder the other day & the moisture content is now @ 16%. Is this due to the time of the year in the Northwest? I am making pedistals for a dinning room table w/this. Laminating pieces so that I can get 4-1/2" sq. blanks prior to turning. Will I have problems w/movement? TIA for the help.
