    • A four-bladed chuck for attachment to a drive spindle of a veneer lathe. The blades include a first flat side for providing a driving area and a second side in a plane perpendicular to the first side of an adjacent blade. The bottom of the second side extends outwardly from the chuck at the outside of the chuck providing an uprise at the outside of the chuck for holding an end of the log for reducing splitting of the log end and holding a split log together. The plane of the second side is approximately 15 degrees relative to the longitudinal axis for reducing splitting. The blades in the uprise are shaped and formed by circular end mill cutter or by casting.
    • 一个用于连接到单板车床的驱动主轴的四叶片卡盘。 叶片包括用于在与相邻叶片的第一侧垂直的平面中提供驱动区域和第二侧面的第一平坦侧面。 第二侧的底部在卡盘的外侧从卡盘向外延伸,从而在卡盘的外部提供上升,用于保持日志的一端,以减少日志端部的分离并将分割的原木保持在一起。 第二侧的平面相对于纵向轴线大约为15度,以减少分裂。 上升的叶片由圆形立铣刀或铸件成形和形成。
