>Sorry this is such a bad photo. I wasn't doing a project that was big enough to have space to really show how the tool works. I'll do another one later when I work on an endgrain vessel.
Most ring tools have 2 sides and both have a different angle on the bevel or outside of the tool. If you rotate the tool so it goes from about 1 oclock to 7 oclock you will usually be close to the right angle for the "sweet spot". This might change slightly depending on the tool you have. Rotate the tool slightly clockwise or counterclockwise until you find the cutting angle.
Hope this helps. I'll try to post a better photo and description when I have time later this week.
