Terry, Glad to see your still in the thick of it. I've been stumbling a bit in my own efforts of late. I'm spending a great deal of time trying to get my house ready to sell. I'm not sure I'll be moving but i have found a possibility that I just can't afford to ignore. Most all our efforts are going in that direction right now. Any idea where I could find one of these charts? Seems that Dave Porritt's gauge looks pretty good for the task. I like the idea of the air fully circulating around the board and therefore will have to build a hot box. Where do you keep yours? I've been daydreaming of hanging it from the ceiling vented above. Any thoughts? Greg Newell At 07:34 PM 8/30/2002, you wrote: >Hi Greg. I am not trying to directly measure moisture content (MC) of the >board.
