Let me start by saying I'm kinda green at running my mill effectively. Most of my experience has been on the lathe. I have a couple of molds that I'm planning on cutting for a hp pin. I'm shooting for a larger Lyman type spud because it's pretty straight forward, just a little larger so that I have the ability to modify the nose shape and the cavity dimensions. Only issue I'm having is centering the cavity. Can I get away with just using a kick out wobble center finder on the base of the cavity? Or do I need to indicate off the sides of the cavity using a plug gauge and center with a dial indicator in the quill. I can see how both would work just look for suggestions before I go to hacking away. Thanks
