I use a tapered cone sanding stone in a Dremel Tool.
I 1st drill the hole for the hinge and mark the width of the knuckle on both sides of the hole then insert the cone shaped stone into the hole and open it up until the mouth of the hole is the proper width. Works pretty good for me.

Same thing, just a smaller burr and mine is designed as a small cutter instead of a grinder. With a new plane still in the bones I drill the holes for the pins before I do any taper. When I sand the taper on the edge the tapered holes come out looking like Suns.
