HMH Tube Vise Converter
The Tube Vise Converter will easily convert your HMH vise with screw-in / screw-out jaws to an in-line rotary tube vise. It offers a whole new way to hold tubes by chucking them directly in the steel jaws. Mount tubes tubes with or without junction tubing installed; with or without pins/mandrels. The sleeker design lets you take full advantage of the in-line rotary ability, and makes it easier to get materials on top, bottom, and sides of the pattern unencumbered by the tool holding the tube. Comes with two premium mandrels, sample tubes, and tube fly hook samples.
