It looks like you want to use a roundover bit on the corner of the piece of cherry? If all you want is a rounded edge, then you would set the bit so the bottom of the curved portion is level with the table. That bit has a bearing, if you intend to use the fence on the table, the fence should be set flush with the bearing (use a steel straightedge). Now, if you want a small fillet or bead on the edge, You would raise the bit to cut the amount you wanted. Finally, if you don't use the fence with that bit your table should have something called a starter pin that should be in place and used to route the piece. This would just be a small straight pin that fastens somewhere to the table a few inches away from the bit. You push the workpiece against it just before engaging the bit. Once the bit is engaged, you move the workpiece away from the pin and route the edge. Hope this is of use.....
With a bit like that, I set the fence even with the bearing... steel straight edge works well for this.
Bit height depends on whether I want a bead along the edge, if not, the vertical edge of the cutter must be just below the table surface, otherwise proud the amount of bead you want. As others have noted, some experimentation is in order here. :smile:
