Using the Differential Shrinkage and the Cupping of Lumber Spreadsheet

By: Phil Mitchell Wood Products Notes

Wood shrinkage is often calculated with the assumption that the radial and tangential shrinkage occurs parallel to the lumber surfaces. As a result, the calculated shrinkage has a built-in error in calculating the change in dimension as it ignores the curvilinear nature of the growth rings. This paper describes an Excel spreadsheet that considers the curvilinear nature of growth rings to calculate the transverse wood shrinkage and the amount of cup that might develop. The model is dependent on wood species, initial and final moisture contents, and location of the board within the log.

Wood Surface Inactivation and Adhesive Bonding

By: Craig Forbes Wood Products Notes

From the instant an adhesive is applied to wood until the adhesive cures, several important steps must take place in order for a good glue bond to occur. If any of the actions do not occur, the glue bond will be faulty. Such is the case when gluing wood which is surface inactivated. The definition, causes, and prevention of surface inactivation in wood will be discussed in this factsheet.
