We’re gonna hold it just for a second or two like that in the Leading Edge. To clean this leading edge up the face and then we’re gonna grind on the backside of the bit slowly. Bringing the bit down until we see sparks hit the front. We’re gonna use all the side of the wheel.
When you’re doing this you look down and see where the center is and when you do one side. And you got your hands in position. You don’t look at it.
Then go back down and do it again. What happens as you lose your hand positioning so to do you look down this leading edge. And you watch the sparks. And you just touch it and you flip it over you don’t move your hands. See what that did is it gave me a clean Edge we can see my surface.

When we are going to sharpen now. We can see how grounded. We swallow they bring it down until we see some sparks coming off the front. The material going down now we don’t get to look at it. We go back off the back. We rotate it to do the other half. Then we start at the back. We go down they see well when we get near the tip. We push less and less hard. So there is their cut. It’s going downhill. So the leading edge is the highest point.
It’s sharp as a razor right now. And both side look about the same decides. A little worse than the other. And we checked for center the other trick with. When we do the face of the grinding so wide. This is here we’re going to narrow that up a little bit. So when this goes on a piece of metal and it’s spinning. It’s not wandering all over the narrower that is better it stays on your mark. It doesn’t wonder as you’re trying to drill. So that just got narrower if you know what we are looking at you see. Its narrower now in the center as we get sharper. We’ve pushed less higher. So we actually have little too steep of a relief angle on this side.
