40-40 Bowl Gouge Grind (Shape, Sharpen, Use) - Turn A Wood ...

While the Vari-Grind Jig is great for so many other bowl gouge grinds, the 40/40 grind isn't one of them. I use 80 grit and 180 grit CBN wheels for my gouge sharpening. The 80 is used to shape or remove more material when needed and the 180 is used for continuous touch-up sharpening. Happy Turning, Kent. Leave a Comment Cancel reply.
