Would like to get some experienced opinions about the preferred rotation direction on chain grinders. Both of my sharpeners have the ability to spin in both directions. My EFCO has been my go to sharpener for a while. I am going to upgrade with a Borazon wheel soon so I have been asking around about the best way to grind..from the file days I always went from the inside to out..which with a wheel would be LH cutter CCW (inside to out) and RH cutter CW (inside to out)..the shop where I buy a few Stihl parts uses the latest Stihl grinder and it sharpens one side in to out and the other out to in....Since I have the ability with either of my grinders with bi-direction...which is best outside to inside or inside to outside? For my little yellow/black grinder if you setup with the indicated switches..it grinds the LH cutters..CW(out to in) and the RH cutters CCW (out to in) Thanks for all opinions especially with the Borazon wheels...BV
