Q: I have just received some glued-up oak panels that we will be using for tabletops. One of our people noticed that the ends of the panels have developed some cracks and more cracks are showing up every 10 minutes it seems. Most of the cracks are at the glue joint at the end of the panels. The supplier says that our shop is too dry (25 percent to 30 percent RH is what we measure now during the wintertime). My people just checked the MC of many panels, including some that have yet to be unstacked and unwrapped; they are getting some readings as high as 10 percent MC (after correcting for temperature), with a lot over 8 percent MC too. We need an outside person to give us an accurate evaluation.
Q: What is ring shake? How do we detect it in our oak lumber? Does this shake cause a bad odor or other manufacturing problems?
