I was lucky enough to take Ray Key's class at Arrowmont, even luckier to be his assistant for the next two years. If the gouge is still close to the original profile, practice with the grinder off. Set the platform as a rest for your left hand, your left hand supports the gouge a few inches behind the tip. Hold the gouge handle or ferrule with your right hand (fingertips, no death grip) and with the gouge tip bevel on the wheel, rotate tool clockwise while lowering the handle, this should be sharpening the right side of the gouge, start rising the handle and rotate the tool counter clockwise, when the flute is at 12 o'clock, start lowering the handle to work the left side of the gouge. What ends up happening is you start to see that you are scribing a small U on the face of the wheel. when you are on the left side of the U you are sharpening the right side if the gouge and vice versa for the left. When you are ready to extend the right wing about 2 inches or so down the side, stay on the right bevel and keep rolling the tool clockwise till the flute is about 9 o'clock, at the same time pushing the tool up the wheel, bringing the edge back as far as you want. Even tho it is called "free hand" you are using your body as a jig. Practice practice practice with the grinder off. Then go for it... Stay loose... I know pics would help, I think there are some in another post but I could not find them. I'm out of town battling a flooded basement, I'll do a better write up with pics when I get home.
