I apologize if this has already been covered elsewhere, but I could not find any reference, either here, in the manual, or on the web regarding the settings for the leg sleeve.
Exactly what does the setting of the sleeve do differently than moving the slide bar in and out? Seems that it simply alters the sharpening angle, but that must not be the whole story, or it wouldn't be adjustable.
Anyone have the true purpose?
Some people like to round over the heel of the bevel on detail gouges (and some do it to bowl gouges). By pulling the collar back, you can grind the primary bevel, then slide forward and soften the heel.
