ABSTRACT:
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.
