Hi Ron, http://www.ca.uky.edu/agc/pubs/for/for55/for55.htm And I quote from the above: "Because wood is a hygroscopic material (meaning that it readily takes up and retains moisture), it is impossible to prevent moisture from entering dry wood" No information on rates--but clearly wood wishes to *retain* moisture which was what I was trying to say in the first place. I.E. it comes out slower than it goes in. Regards, Don Rose, B.Mus., A.M.U.S., A.MUS., R.M.T., R.P.T. mailto:pianotuna@accesscomm.ca http://us.geocities.com/drpt1948/ 3004 Grant Rd.
