Here's a good explanation of ring and wind shake;http://www.woodcentral.com/shots/shot137.shtmlThe following isn't shake but very importantnon the less.This is one you have to watch out for that wasdiscovered through the failure of new woodladders many years ago.What happens is that a tree is felled and landsacross another trunk. This causes the grain to"shift" sideways just a small bit, sometimes onlydetectable under magnification. This is enough toseriously impair the integrity of the grain. In a sparthis will be catastophic.ClifThere is a crack in everything God has made.- - - - - - - - - - - - - - - - - - - - - - - - - ---William Blake> > Ok, this leads to the next question, are those fractures "wind shake" fractures?- I've read about them with respect to grading sitka, but have never seen them in all the other species of wood I've worked.le, List Admin.________________________________________________________________________________
