3 weeks back there was some discussion on how wood looses it's moisture so I decided to do a little test. First was to work out how big a part bark has on moisture loss and the second was to see how much different end grain is to straight grain. In this picture you can see the samples.

2 log but with bark taken off on lathe 
3 wood turned from piece to side of center of tree so all growth have been cut through
