Q: I have recently launched a problem-solving effort that is focusing on small surface cracks and glue joint cracks in our final product. Most of what I have read takes me to the kiln drying process; however, we do not dry lumber and we receive material in several different species from domestic and overseas suppliers. I am looking for a method to understand what causes these failures to better establish moisture content tolerances on our incoming material. Our raw material warehouse and plant both have a humidification system. Material generally is turned over within 10 days after receipt. Oftentimes, I do not see the cracks until after finishing. I am also subjecting the material to convection heat in the finishing process - is this a factor? As we have several variables within our process, what would the best approach be to establishing incoming tolerances and/or internal controls that protect us from splits?
