How do you know if you have dressed grinding wheels properly?
I have a regular speed 8in dry grinder with a 36 grit (stock) wheel. It seems to be taking me way longer than I think it should to grind LV and Hock plane blades. They are a mix of O1 and A2 steels. I suspect that perhaps I am not dressing the wheel enough, but I don't know how to tell this. Any suggestions or tips?
I have used 3 different dressers. The stock one has wheels with teeth. It makes plenty of sparks. The second one is a black bar that a machinist gave me. I don't know much about it, but he said it was the thing to use. It makes very little spark. The third is a Norton diamond dresser. To me, they all seem to work the same, but I know nearly nothing. I hold them to the stone with a light touch and move across the stone for about 60 seconds. Any help is appreciated. thanks
