Description: Computer simulation was used to gang rip No. 1 and No. 2 Common red oak boards before and after removal of crook. While No. 1 Common produced slightly more total yield, the part yields were very similar. No. 1 Common was superior only in yielding 75-inch-long pieces. Either grade is an excellent choice for the furniture and cabinet industries.

Keywords: Lumber grades, rough mills, lumber processing, lumber breakdown, value-added
