Over years I’ve used almost every type of bench grinder dresser on the market, But I’ve never been completely happy with any of them. Star wheels do a good job of opening up the grinding wheel but don’t always produce a flat cutting surface. Carborundum sticks do an okay job of opening the pores, but they too don’t always yield a flat surface. T-handle diamond dressers produce a very flay face in my experience, but have a tendency to dull the wheel. The only type of Dresser I haven’t use is the single point type, mainly because the few that are commercially available wouldn’t work well with any of the grinders I’ve owned.
Back before Christmas, I decided it was finally time to give a single point dresser a try, so I sat down and designed one, that would work with my current grinder. The following video shows making the small parts associated with it.
