Thanks guys!

I only did the step (versus going all the way through) since it is end grain.
With the step, I could use a top/bottom bearing bit to finish the flush-cut so I was always cutting the grain downhill. Helps prevent tearout for a much easier cleanup.

I've had enough disasters from a bit catching end grain the wrong direction and launching or exploding the part. Now I'll do most anything to avoid that.

Dave, I do have a spoke shave, but on end grain I probably would have done more damage. Anyway, the sanding was minimal and came out smooth!
