Here is a pic and a summary of how to bevel with a sander or grinder for those still learning or wanting to learn. Note the black line and pretend it is the line of a snapped board that is glued back together. Now note the red circle and the left and right arrow. The left arrow indicates the left side of the pad/disc clearing by a little bit from the edge of the circle leftward. The right arrow indicates the right side of the pad/disc clearing even further. The back arrow indicates the back of the pad/disc being lifted a little bit. I’ll leave the rest to your imagination.
