Mary asked “Any more suggestions on determining grain direction on .098 in (2.5mm) Davey board? I’m having an awful time figuring it out.” Mary is right. Sometimes it is difficult to determine board grain direction. Wetting one side of the board and seeing which way the board warps is a very reliable test in this situation. I'll demonstrate this in this short video. At the start I use the bend test to determine the grain direction of full sheets of binders' board.
