The effects of crosscutting before gang-ripping on dimension part yields from no. 1 and 2A common red oak lumber

Abstract

Mills should have the option to crosscut red oak lumber prior to gang-ripping to remove crook and worthless material and to take advantage of the quality differences between board ends. At least half of No: 1 and 2A Common red oak boards will have end-to-end yield differences of at least 10 percent. Preprocessing will cause a slight decrease in overall yield but will allow greater control of the material fed to the gang ripsaw. It also appears that fewer short lengths will be generated from the better sections of the boards.
