When turning the interior of a vessel, whether a bowl, goblet, etc., I have been using a 1/2" bowl gouge for most everything. There are some areas where catches tend to occur, however, and I'm wondering if I'm using the wrong tool for this. The most troublesome area for me is around the inside of the neck. I think this may be because the wing of the gouge is coming into contact with the inner shoulder of the vessel. A scraper seems to cause quite a bit of tearout -- I suspect this is an issue with the sharpness of the tool, though (I haven't got the appropriate rest for sharpening the scraper yet). What is the best tool to use in this area?
