Well, I also posted this over at WC, but have to ask here as well. With the advances in abrasives, I am seeing grits of 260 and 280 in the fine range. After using them, I don't really like them. They do fit into the next grit up formula (that grit number plus half as in 180 + 90 =270). Main reason is that whenever I step up from 180 to the next grit, I always seem to find some 120 scratches. They come out fairly easily with 220. Some turners even go from 120 to 220 without using 180. Problem with the 260 - 280 is that it is very difficult to get those scratches out.
Any one else run into this?????
