Now, my layers of eye protection are ... the shield next to the grinding wheel, then the optivisor lenses, then my safety glasses, then my seeing glasses.
The next thing I need to learn is to regrind the primary and secondary faces on the flutes. It looks like I need to get a 6 inch wheel for that operation.
