So, I "borrowed" a microscope from work (they'll never miss it). Took an inexpoensive HSS SRG, and sharpened in various ways. Here are the micrographs: Dry grinder, 80 grit CBN wheel: Dry grinder 180 grit CBN wheels: Tormek immediately after leveling stone (no grading): Tormek after rough grading and honing the flute: Tormek after fine grading and honing the flute: No, I did NOT switch these photos. Weird huh? More photos in next post. I hit the 5 photo maximum.
