We're going to be doing a retipping.  And whenever we do a retipping I prefer to have it ground down so that the angle meets the angle coming off the stone.  Now first off what I'm going to do is shoot my little wire, make a nice little ball.  A little more. With this ball I will squeeze it down and I have my wire, made myself a little pad.  Take that, place it over, and fire.  Now here I can adjust it can move it and make sure it's sitting down over the stone.  Looks good.  And you know I hit it from the other direction.  Now we can add wire.  And we can even add wire if you feel like it.  There we go, one retipped prong.
