All,
I converted to a hollow grind. I first used a jig and ground flat bevels on a course india stone and then a small secondary - it took forever and wore out my patience. The I went freehand with the convex bevel again on the norton ib8 stone and an occasional trip to 80 grit paper to take off hump and the corners - better than the jig and flat bevel but... Then I got a little hand cranked grinder and tried the hollow grind...I like this route much better and don't expect to change from it. So hollow grind, norton fine india, and an old hard ark stone is where I ended up. I do use green crayon on mdf for the final smoothing pass occasionally.
