Finished the new larger guards today. I've been using white aluminum oxide wheels for years, thinking they kept the material being ground cooler, then after watching Tom's sharpening tutorial it dawned on me anything I sharpen in the machine shop is HSS and there's no need to keep it that cool. These wheels stay true and will keep a sharp corner for forming split point drills. The cabinet shop requires the aluminum oxide as most of my chisels and plane irons are high carbon steel which are heat sensitive.
These wheels are Norton marked fine and 60/80 grit, even the 60/80 is pretty fine, had to go back to the rough grinder to form a shaper tool then finish it on this grinder.

Free advice is worth exactly what you payed for it.
