Think of the Hunter as a finishing tool. You can hollow an object completely with the Hunter Tool, but most turners rough hollow with conventional tooling. They then use the Hunter Tools for the final form, shaping, and finish cuts.
The Hunter Tools are best used at higher RPM (1800-2200 RPM) to have sufficient surface speed. With fine tool control you can peel off shavings that are onion skin thin. The surface will be so smooth that little sanding will be needed. Of course as with any other cutting tool you will be cutting with the grain for the smoothest cut. So for the underside of box rims, cut from the rim to the major diameter of the body of the box. Once you reach that diameter, lift the tool and cut from the bottom upward to the major diameter of the body of the box. It is mesmerizing to peel of these ultrafine shavings so be careful or you may make the inside merge with the outside....
There is a learning curve with the Hunter. You have to learn to rotate the tool clockwise into the cut with the tool slightly above center and angled downward somewhat like a scraper. The tool does not scrape; it cuts like nothing you have ever seen. Don’t expect to hog out the interior of a box or something similar quickly. The tool is not designed for that … it is a final form and finish cut tool.
These Hunter Swan Necks are real problem solvers. With practice, you will have very little sanding to do. By the way, the harder and more dense the wood the better the Hunter tool seems to like it.
