The last one I did I used a round stone on a drill, that had a flat face. It was just slightly larger than the washer. I walked it back & forth over the edge, if you can imagine that.
I know OE valley pans need doctoring, will have to look and see if my Tomahawk was doctored or not. Some reason I'm thinking no, but it's been a while.
