I would like to just throw this out there for others opinions or uses. I use my 10" independent 4 jaw mounted chuck for holding work that exceeds the opening of my table vise or odd shaped work. It has the advantage of not needing to space the work off the table surface because of the stepped jaws. The work I show below is an oval 9x10x3/8" that calls for a 3 1/2" hole with final sizing using my bore tool. It also works well with round stock. Granted the lathe can accommodate odd shapes, but that means a face plate swap. Thanks, Charlie
