Just a quick head's up here folks. I just got a new wheel dresser from Lee Valley and it seems to be great. I have only used it the once but it looks like it should last and do a great job. I dressed the grinder and tried it on a couple of gouges and the results are great. One warning. This thing is
36 grit and produces dust like nobody's business. Be cautioned. The surface on the stone and on the tool are great.
