EXPANDABLE WOODTURNING CHUCK

摘要

The present invention relates to an expandable chuck for faceplate woodturning. The chuck is of simple construction for attachment to a conventional faceplate. A frusto-conical plug drawn towards the faceplate expands a radially segmented annular member. An annular resilient ring biases the annular member against expansion. Preferably a keeper also prevents disintegration of the segmented annular member under high centrifugal stress.
