After a spin in the water bucket, Imark the top with a "T" , then drill them out, the jig I use has a locating pin which I push the plug onto, I then have a wedge that I slide under the tail of the plug, I use a small bubble leval to make sure the face of the plug is getting cut on a 90 degerr bias witht the belly hole, the wedge is moved fore or aft to center the bubble, the wedge is moved after each angle cut, so I normaly will do a dozen or so at a time....
