8 to 24 inches of swing across all 7 lathes here, by each maker's published figure.
The figures are the makers' own, cited on each tool's page. Because makers state some figures differently, compare the wording and not only the number, and check each manual for what your shop calls for.
Each pick is the one of the 7 lathes here that comes first on a single figure its maker publishes. None is a judgement of quality; we have not tested these tools. Whether we earn a commission on a tool never decides a pick.
