Compression Chuck for a Lathe
Shop-built chuck holds bowls tightly, so you can turn a foot
Synopsis: A nicely finished foot on the bottom of a turned bowl is a feature that separates the work of a pro from that of a beginner. The biggest problem, says woodturner Dale Ross, is how to hold the bowl in the lathe. Ross made several compression chucks quickly and inexpensively that handle bowls from 4 in. to 14 in. He explains how compression chucks work and how to make one — from how to make the baseplate and how to turn the jaw plate, platen, and handwheel. He also explains how to use a compression chuck.
A nicely finished foot on the bottom of a turned bowl is one feature separating the work of a pro from that of a beginner. A well-proportioned foot lifts the bowl and gives it a classic look typical of pottery. Turning a foot also eliminates the mounting screw holes on the bottom of the bowl.
