The Ultimate Deep Hollowing Chuck?
Well, it offers an extremely powerful grip for the price! The coil grip chuck was designed before its time. First made in 1972 it was superseded a few years later by expanding chucks for bowls. Now that "hollow vessels" are in vogue the coil chuck is staging a comeback. It could have been purpose designed for deep hollowing projects - it is quite capable of holding the largest projects that most lathes will handle. It is also very handy for small projects such as goblets and vase forms. The picture shows the chuck and a typical project which in this case is 14" high and 10" diameter. The chuck is 4,1/2" diameter.
