Thanks guys I appreciate the response. Also the tip about not breathing the dust is a good one. Now too order the diamond wheel, my flinter eats up the flints I have tried angles and depths and all sorts of ways to try to get more life but I have used up a heap of expensive flints. I am going to try some black english flints next time out. I shoot a cva plainsman 50 cal flinter and when it goes off quickly its as good a shooter as I've seen.
