When you chase a ring, is it best to get down to early wood and then scrape it off? Seems like it would take forever. I've been getting down to early and then taking it off in really thin shavings with my drawknife. And when it's said not to violate the back ring, how much can you get away with? If you had a 3/8" ring, for instance, and you accidentally gouged 1/16" would it ruin it or can you get away with taking a little off in places? I guess it probably depends some on the draw weight and the stave itself.
